`autocomplete_naics`Autocomplete lookup for NAICS codes. Accepts partial codes ('541') or keywords ('software'). Returns matching NAICS entries with code and description. Minimum 2 characters required. Short queries silently match substrings inside parenthetical notes (e.g. 'x' matches 'except') and produce nonsense results, so we require 2+ chars. exclude_retired defaults to True. The upstream NAICS taxonomy still returns codes retired in 2012/2017/2022; these are almost never what callers want. Set exclude_retired=False to include them.	Autocomplete lookup for NAICS codes.

`autocomplete_psc`Autocomplete lookup for Product/Service Codes (PSC). Use exact four-character codes ('R499', 'D302') or description keywords ('professional', 'application'). Returns matching PSC entries with code and description. Two-character families such as 'D3' can return no autocomplete matches even when their descendant codes exist. For partial PSC families or prefix expansion, use get_psc_filter_tree() instead: path='Service/D/D3/' lists the D3 descendants; start with path='Service/A/' to discover and drill into an AJ family. Minimum 2 characters required. Single-character queries return first-N alphabetical results from the upstream API (useless for matching) and empty strings return HTTP 400.

`autocomplete_recipient`Find recipient names by partial name or UEI/DUNS. This is a recipient-name lookup; it does not supply the recipient hash for get_recipient_profile() or new_awards_over_time(), and its UEI/DUNS fields may be null. Pass a returned name to search_recipients(): use its 'id' hash for profiles/trends, and the UEI (or legacy DUNS) from the parent (-P) row for get_recipient_children().

`get_agency_awards`Get one obligation total and transaction count for an agency's awards in a fiscal year. The total covers ALL award types together (contracts, IDVs, grants, loans, direct payments, other), so for most civilian agencies it is far larger than contract spending (VA FY2026: $313B here vs $84B contracts). For the split by award type use get_agency_obligations_by_award_category(). toptier_code is auto-padded to 3 digits if a shorter numeric value is supplied. fiscal_year defaults to the last completed fiscal year, not the current one (USAspending's own default, which right after October 1 holds only a few days of data). The answer always carries fiscal_year.	Get one obligation total and transaction count for an agency's awards in a fiscal year.

`get_agency_obligations_by_award_category`Get an agency's obligation breakdown by award category. Returns total obligated dollars split by category: contracts, IDVs, grants, loans, direct payments, other. Quick way to see what mix of award types an agency uses (heavy contractor agency vs grant-issuing agency vs mixed). For DoD ('097') a fiscal year whose last 90 days are not yet published (DoD's 90-day delay) carries a data_note saying the total is understated. fiscal_year defaults to the last completed fiscal year, not the current one (USAspending's own default, which right after October 1 holds only a few days of data).

`get_award_count`Count awards matching filters, broken down by award category. Returns counts grouped by: contracts, idvs, grants, loans, direct_payments, other. Use this for dimensional analysis: how many FFP vs T&M awards, how many competed vs sole-source, how many small business set-asides, etc. Unlike search_awards, this returns total counts across ALL award categories in a single call (not just the one specified in award_type). The award_type parameter is ignored here; filters apply to the count query directly. def_codes filters to Disaster Emergency Fund codes; see get_def_codes_reference(). At least one filter is required (the API rejects empty filter sets with HTTP 400). Typical usage: pass time_period_start + time_period_end, or a keywords/agency filter. date_type controls the award date window. Omitted (the default), the latest action must be on/after the window start and the first signing on/before its end. This interval overlap does NOT prove an action occurred inside the window. For actual dated actions use spending_by_transaction, read every page, and deduplicate award identifiers for distinct awards; get_transactions provides a discovered award's complete action history. 'action_date' bounds the latest action, not any action; 'date_signed' bounds first signing; 'last_modified_date' bounds the latest update. 'new_awards_only' keeps awards first signed in the window. date_type needs time_period_start and/or time_period_end. program_numbers filters assistance awards by assistance listing (CFDA) number, e.g. ['93.778'] for Medicaid; use it with award_type='grants', 'loans', 'direct_payments', or 'other'. autocomplete_cfda() finds numbers by program name.

`get_award_detail`Fetch full details for a single award by its generated_internal_id. Use the generated_internal_id value returned by search_awards to fetch the complete award record. Returns: PIID, full description, total obligation, recipient details, parent award info, latest transaction contract data (competition, set-aside, pricing type), period of performance, place of performance, NAICS hierarchy, PSC hierarchy, base and all options value, and sub-award totals. Award-level outlays and total_account_obligation are partial or lagged File C measures, not a reliable amount paid; compare with total_obligation for coverage. Accepts either a generated award id (CONT_AWD_, CONT_IDV_, ASST_NON_, ASST_AGG_) or the numeric internal database id from a prior response.

`get_federal_account_fy_snapshot`Get a single-fiscal-year snapshot of a federal account's resources. Important: this endpoint takes the numeric `account_id` (e.g. 4595), NOT the alphanumeric `account_number` (e.g. "027-5183") used by the other federal-account endpoints. The list_federal_accounts response includes both fields per record. Pass the integer account_id here.	Get a single-fiscal-year snapshot of a federal account's resources.

`get_federal_account_object_classes`Get the object class breakdown of obligations for a federal account. IMPORTANT: the returned obligations are CUMULATIVE across all reported fiscal years (FY2017 onward, the DATA Act window), not a single year. They are NOT comparable to get_federal_account_fy_snapshot(), which is single-year (verified live: account 021-0725 summed to $3.38B here vs $0.42B obligated in its FY2024 snapshot). The upstream endpoint has no year control: a fiscal_year body parameter is accepted but ignored, so none is exposed here.

`get_federal_account_program_activities`List program activity codes and names associated with a federal account. The source lists distinct programs across all reported fiscal years; it has no fiscal-year filter and includes no dollar amounts. fiscal_year is retained for compatibility, but does not filter this list. The response explicitly discloses any requested year that was not applied. Retrieves source pages internally, up to 2,000 records, and reports whether the list is complete. For single-year account resources and obligations, use get_federal_account_fy_snapshot with the numeric account_id returned by list_federal_accounts. get_agency_program_activities provides fiscal-year program amounts for an agency, not for this individual federal account.

`get_idv_activity`List child task/delivery orders awarded under an IDV. Results are ALWAYS sorted by obligated amount, descending; the endpoint accepts no sort or order parameters. (Earlier releases exposed sort/order here, but the API silently ignored them: the advertised default of period_of_performance_start_date was never the actual ordering. Round 10 audit finding.) For date-ordered children use get_idv_children(), whose endpoint does honor sort/order. hide_edge_cases=True filters out child awards missing obligated/awarded amounts or end dates.

No	Yes	Not declared	Yes
`get_idv_children`Fetch child awards (task/delivery orders) under an IDV. For a Multiple Award IDV, child_awards returns the task orders or delivery orders placed against it. For a parent IDV, child_idvs returns the downstream IDV structure. grandchild_awards walks the hierarchy. Field name differences from search_awards: children use 'piid' (not 'Award ID'), 'obligated_amount' (not 'Award Amount'), and 'generated_unique_award_id' (not 'generated_internal_id'). An active vehicle can legitimately return zero children here: USASpending's award cross-linking has gaps. Treat an empty result as a reporting gap, not proof that no orders exist. Try get_idv_activity() on the same id. A search_awards call with keywords=['<IDV PIID>'] only finds orders whose description happens to cite the IDV, so it misses orders (often the largest) and is no proof of completeness.

`get_recipient_children`Get the child recipients (subsidiaries) of a parent recipient. Pass the parent recipient's 12-character UEI (or legacy 9-digit DUNS). Do NOT pass a recipient hash: the /recipient/children/ endpoint is the one recipient endpoint keyed by UEI/DUNS, and it rejects hashes with HTTP 400. Get the UEI from search_recipients() results (the 'uei' field of the -P row) or from get_recipient_profile(). Returns the child recipients, each with its own -C suffixed recipient_id hash usable with get_recipient_profile(). Useful for mapping corporate structures (e.g. Lockheed Martin parent -> all its subsidiaries). year: optional 'all', 'latest', or a fiscal year like 2026. The upstream endpoint returns a JSON array; it is wrapped here as {"results": [...], "total": N} to keep the dict-only response invariant.

`get_recipient_profile`Get full profile for a recipient by their USASpending hash. Returns recipient details: name, UEI, DUNS, business categories, location, parent (if any), and lifetime award totals. The hash is the 'id' field returned by search_recipients(). (autocomplete_recipient does NOT return hashes; it is a name lookup only.) year: optional 'all' or a fiscal year like 2026 (int or str both accepted). Default is 'latest' (trailing 12 months).

`get_state_profile`Get the federal award totals for recipients located in a US state. Examples: '06' = California, '48' = Texas, '24' = Maryland, '51' = Virginia. Returns one summary: state name and code, total_prime_amount and total_prime_awards (all award types together), loan face value, award_amount_per_capita, total_outlays, and population / median household income (older Census vintages: see pop_year and mhi_year). It has no breakdown by agency, recipient or district; for those use spending_by_geography() or spending_by_category() with a time window. year: a fiscal year like 2026, 'all' (every year on file) or 'latest' (USAspending's own default: the current fiscal year to date, which right after October 1 holds only a few days of data).

`get_transactions`Fetch the full transaction (modification) history for an award. Every modification, option exercise, and de-obligation is a transaction. Modification number '0' is the original base award. Use to understand the full lifecycle of a contract including its descriptive text at each point in time. Returns per transaction: id, type, action_date, action_type, modification_number, description, federal_action_obligation.	Fetch the full transaction (modification) history for an award.

`lookup_piid`Look up awards by their exact PIID, across contracts AND IDVs. Looks for awards whose own PIID is exactly this value (the award_ids filter), in both contracts and IDVs, and says how many share it. match='exact' rows are the awards themselves: an IDV PIID returns the IDV (award_type='idv'; its Award Amount is what was obligated on the IDV record itself, usually 0, so use get_idv_amounts() for the order total). PIIDs are not unique: task and delivery order numbers like '0001' repeat under different parent IDVs, so check 'ambiguous' and tell matches apart by parent_idv_piid and Awarding Agency. Only when nothing has that exact PIID does it fall back to keyword search, and those rows come back as match='fuzzy': keyword search matches the award's own PIID and its description text, NOT its parent IDV, so a vehicle PIID or prefix returns only orders whose description happens to cite it. For the orders under a vehicle use get_idv_activity() or get_idv_children() with the IDV's generated_internal_id; for a contracting-office prefix (N00024, W91CRB, FA8650) use search_awards keywords with a time window. limit applies to contracts and to IDVs separately. Use get_award_detail() with a returned generated_internal_id for the full record. Handy for enriching PRISM, Contract Court, or FPDS exports where you have a PIID but don't know whether it's a contract or IDV.	Look up awards by their exact PIID, across contracts AND IDVs.

`new_awards_over_time`Pipeline trend of new awards to a recipient over time. REQUIRES recipient_id (the recipient hash with -P suffix for parent-level rollup, or -R for a single recipient). Returns counts of new awards grouped by month, quarter, or fiscal year. The endpoint rejects calls without recipient_id with HTTP 422, and it also requires a time_period. When you omit the dates, a default range covering all searchable data (2007-10-01 through 2099-09-30) is sent automatically.	Pipeline trend of new awards to a recipient over time.

`search_awards`Search federal awards (contracts, IDVs, grants, loans, etc.) on USASpending.gov. This is the primary workhorse for finding awards. Returns matching awards with standard fields (Award ID, Recipient, Description, Amount, Agencies, NAICS, PSC, dates). Use get_award_detail() with the generated_internal_id from results to get full award details. Important rules: - award_type groups cannot be mixed; pick one category per call - time_period_start/end use YYYY-MM-DD format - award_amount_min/max are in USD - place_of_performance_state is a 2-letter USPS code (e.g. 'MD', 'VA') - For loans, use award_type='loans' and sort='Loan Value' - def_codes filters to Disaster Emergency Fund codes (COVID-19, IIJA, IRA supplementals); see get_def_codes_reference() for the list Filtering to specific contracting commands (NAVSEA, AFRL, etc.): USASpending's subtier level is at the service branch (Department of the Navy, Army, Air Force), not the contracting command. To filter to a specific command, use keywords with the PIID office prefix instead: - NAVSEA contracts: keywords=['N00024'] - Army Contracting: keywords=['W91CRB'] - AFRL: keywords=['FA8650'] - NAVAIR: keywords=['N00019'] This performs a substring match on the PIID field and is more reliable than the award_ids filter for partial matches. Common filter value references: - set_aside_type_codes: SBA, SBP, 8A, 8AN, HZC, HZS, SDVOSBS, SDVOSBC, WOSB, WOSBSS, EDWOSB, EDWOSBSS, VSA - extent_competed_type_codes: A (Full & Open), B, C, D, E, F, G, CDO, NDO - contract_pricing_type_codes: J (FFP), Y (T&M), Z (LH), U (CPFF), V (CPIF), R (CPAF), L (FP Incentive), M (FP Award Fee) IMPORTANT: awarding_agency/funding_agency must be the FULL TOPTIER NAME, not a slug.

`spending_by_category`Aggregate spending by a dimension (top vendors, top agencies, top NAICS, etc.). The 'category' parameter controls the grouping dimension. Common uses: - category='recipient': top vendors for a filter set (vendor landscape analysis) - category='awarding_subagency': which contracting offices within an agency - category='naics': which work categories got the most spending - category='psc': which product/service codes got the most spending - category='state_territory': geographic distribution - category='cfda': grant assistance listings Note: recipient category returns vendor names in ALL CAPS and may contain duplicates (subsidiaries, rebrands, re-registrations). For precise market share, apply name normalization to the returned 'name' field. At least one filter is required. An unfiltered call would silently aggregate the entire USASpending database (all years, all agencies), which is never what a caller wants. date_type controls the transaction date window. Omitted (the default) or 'action_date', it selects transaction actions inside the window. 'date_signed' selects the associated award's first signing date; 'last_modified_date' selects transaction update dates. 'new_awards_only' retains in-window actions associated with awards first signed in the window. These are transaction obligation totals, not new-award counts: use new_awards_over_time for counts. Award search/count tools use a different default interval-overlap rule. date_type needs time_period_start and/or time_period_end. program_numbers filters assistance awards by assistance listing (CFDA) number, e.g. ['93.778'] for Medicaid; use it with award_type='grants', 'loans', 'direct_payments', or 'other'. autocomplete_cfda() finds numbers by program name.

`spending_by_subaward_grouped`Find matching prime awards and their cumulative FFATA report totals. Filters select prime records, but subaward_count and subaward_obligation cover all reported subawards under each prime, not just subaward actions within time_period_start/end. This ranking is not a fiscal-period subaward ranking. For dated reports, pass a returned award_generated_internal_id to search_subawards(award_id=...), read every page, and retain action_date values inside the desired period. sort accepts: award_id, subaward_count, award_generated_internal_id, subaward_obligation. (These differ from search_subawards, which sorts by amount/action_date/etc.) Anything else returns HTTP 400 from the API. page_metadata.hasNext is worked out here: the endpoint itself always says false, even with more pages. Rows include primes with no subawards (subaward_count 0). subaward_obligation sums FFATA reports, which can repeat cumulative amounts, so a subaward_to_award_ratio above 1 is a reporting artefact, not more subcontracting than the prime. program_numbers filters assistance awards by assistance listing (CFDA) number, e.g. ['93.778'] for Medicaid; use it with award_type='grants', 'loans', 'direct_payments', or 'other'. autocomplete_cfda() finds numbers by program name.

`spending_by_transaction`Search at the transaction (modification) level. Unlike search_awards which returns one row per award, this returns one row per transaction (initial action plus every modification). Useful for tracking obligation events over time, ceiling adjustments, deobligations, and admin mods. recipient_uei is matched through the API's recipient text search (which covers name, UEI, and DUNS), so pass the plain 12-character UEI. Returns standard transaction fields: Action Date, Mod, Award ID, Action Type, Awarding Agency, Recipient Name. program_numbers filters assistance awards by assistance listing (CFDA) number, e.g. ['93.778'] for Medicaid; use it with award_type='grants', 'loans', 'direct_payments', or 'other'. autocomplete_cfda() finds numbers by program name.

`spending_over_time`Aggregate spending amounts over time, grouped by fiscal year, quarter, or month. Use this to visualize spending trends, identify fiscal-year-end spikes, or compare spending patterns across years. Note: The API returns fiscal_year as a STRING. Cast to int for numeric comparisons. quarter and month are FISCAL periods (month 1 = October, quarter 1 = October-December). Buckets are clipped to the window, so a calendar-2025 window returns a partial fiscal_year '2025' (January- September only) and a partial '2026' (October-December); neither is that whole fiscal year. DoD contract actions are published 90 days late, so when the window reaches into the last 90 days and DoD is in scope the answer carries a data_note: those months are understated, so don't read them as a drop. awarding_agency must be a TOPTIER agency name ('Department of Defense'). Military departments are subtiers: pass awarding_subagency='Department of the Navy'. A non-toptier name in awarding_agency (or a subagency that does not belong to the given toptier) silently returns all-zero aggregates. At least one filter is required (the API rejects empty filter sets with HTTP 400). Typical usage: pass time_period_start + time_period_end. date_type controls the transaction date window. Omitted (the default) or 'action_date', it selects transaction actions inside the window. 'date_signed' selects the associated award's first signing date; 'last_modified_date' selects transaction update dates.
