`distill_status`How fresh is each Distill dataset right now? For every dataset: the as_of and last check its answers carry, the refresh cadence, the next expected update, its current confidence and whether it is late. Read from live answers: each dataset’s probe route answers its example, and the status reports what that answer says. fresh: checked within its cadence; due: within one and a half cadences; stale: later; unavailable: no answer now. Free; also at /status (HTML) and /status.json. Refreshed daily (live freshness: /status). Price: free. Answers in a summary view of about 2,500 tokens; view: "full" for every row. Confidence: The lowest current confidence among the datasets listed (each by its own route’s formula), 0 when one is unavailable. Freshness of the data behind each route; it does not check any single answer.	How fresh is each Distill dataset right now?

`drug_nadac`What do US pharmacies pay for this drug? CMS’s National Average Drug Acquisition Cost (NADAC) per unit for an NDC, the generic’s NADAC for a brand and the weekly price history since January 2025, from CMS’s NADAC files on data.medicaid.gov. From CMS’s weekly NADAC files on data.medicaid.gov (2025 on): the current per-unit NADAC of one NDC, its effective date and explanation codes, the corresponding generic’s NADAC for a brand, the range over NDCs with the same description, and every price period since January 2025. An NDC never listed answers 404 and is not charged; one no longer listed answers with listed: false and its last NADAC. Refreshed weekly (live freshness: /status). Price: $0.01 per call. Free tier: 3 free answers a day (UTC) per IP for this family's tools, at most 3 rows per answer; calls through Claude's connectors share one daily free allowance per family instead. An unpaid call takes one unless its _meta["distill/free-tier"] is "skip". Answers in a summary view of about 3,000 tokens; view: "full" for every row. Confidence: Freshness only (the values are CMS’s, read deterministically): 1 until 9 days after the latest weekly file’s as-of date, then halving every 14 days. National Average Drug Acquisition Cost as CMS publishes it weekly: a survey average of what retail pharmacies pay per unit, not a retail price, a reimbursement rate, a quote or medical advice.

`hospital_prices`What does a procedure cost at hospitals near this ZIP? Cash price, gross charge and every insurer’s negotiated rate for a CPT, HCPCS or MS-DRG code at Colorado hospitals, normalized by Distill from the hospitals’ federally required price files. From the machine-readable standard-charge files hospitals must publish (45 CFR 180), parsed and normalized: for each hospital within the radius that posts the code, nearest first, the gross charge, the discounted cash price, the de-identified minimum and maximum, and every payer and plan’s negotiated dollar amount or percentage (with the v3.0 median, 10th and 90th percentile allowed amounts), payers canonicalized to a stable payer_id. Filters: payer, plan type, plan name text, setting, billing class. A summary gives nearest-rank statistics over the hospitals returned. Served states: Colorado. An area with no hospital posting the code answers 404 and is not charged. Refreshed monthly (live freshness: /status). Price: $0.02 per call. Free tier: 3 free answers a day (UTC) per IP for this family's tools, at most 3 rows per answer; calls through Claude's connectors share one daily free allowance per family instead. An unpaid call takes one unless its _meta["distill/free-tier"] is "skip". Answers in a summary view of about 3,000 tokens; view: "full" for every row. Confidence: Mean over the returned rows (each rate; an item with no rate counts once) of normalize × quality × freshness. Normalize: the stored per-rate normalize confidence (payer canonicalization: rule 1, model 0.9, fallback 0.6; rate basis for rates with no dollar amount: rule 1, model 0.9, fallback 0.75; 1 for an item with no rate). Quality of the MRF: 1 valid against the v3.0 schema, 0.85 parsed with conformance errors, 0.7 parsed only after header repair. Freshness: 1 while the MRF’s last_updated_on is at most 365 days old, then halving every 180 days (0.5 with no date), times 1 within 14 days of our fetch, then halving every 30 days.

Every PDP and Medicare Advantage drug plan with tier, prior authorization, step therapy, quantity limit, premium and copay, plan years 2026 and 2027, computed by Distill from CMS’s monthly formulary files. From CMS’s monthly Part D formulary public use file: every stand-alone (PDP) and Medicare Advantage drug plan sold in the county (by SSA county code, or state and county name), whether its formulary covers the drug (RxCUI, or the NDC the file lists), and on what terms: tier, prior authorization, step therapy, quantity limit, negotiated-drug flag, the plan’s premium and deductible, and the 30-day initial-coverage cost sharing for that tier at each pharmacy type. Covering plans come lowest tier first, then lowest premium. Pass plan_year=2027 for open enrollment. Employer and PACE plans are not in the file. Refreshed monthly (live freshness: /status).
