`changes_since`Everything recorded since a date, for a model whose knowledge ends at a cutoff: price changes, new items, removals and retirements, newest first, each with its UTC date, the previous good snapshot, the source URL and a permanent link to the item. counts are for the whole period (not just the page); gaps names the sources that are stopped now, with the day they stopped (never filled in; outages that recovered are not recorded); record_begins says how far back the record goes. summary=true returns the largest percent moves per category (at most 40 entries) in one answer, ordered by size of the move, not by price. Paging: pass next_cursor back as cursor. Entries carry recorded values only, never a current price. Returns an error object for a bad date or filter. Same data as GET /v1/changes-since. Use this one to page through every entry or to filter by category and kind (price_change, new_item, removed_or_stopped, retirement); for a first look at what changed since your cutoff, with counts, scope llm/gpu/vps and the gaps, call what_changed_since instead.

`cheapest_for_spec`Cheapest active SKUs meeting a minimum spec, ranked by list price only (no sponsorship, no affiliate weighting), excl. VAT (VAT-inclusive plans are ranked after removing their stated VAT rate; rank.vat_basis says so). gpu and vps default to commitment=on-demand: spot, reserved, committed, dynamic and community-cloud prices are left out unless commitment says otherwise. category vps\|gpu\|llm; vcpu, ram_gb, disk_gb minimums; gpu model substring (e.g. H100; with a memory size such as A100-80GB the card must state exactly that memory); region 'eu' for EU-deployable; currency USD\|EUR for the ranking. Each row carries verified_at, stale and source_url. coverage_gaps names the providers not read yet (for vps: those still named in the answer), so a floor is never mistaken for the whole market.

`estimate_cost`Itemised cost of a usage profile at the SKU's current list price: tokens (input/output/cached) for LLM SKUs, hours/months for instances. Returns line items with the rates used, native, USD and EUR totals, verified_at and source_url. Pure arithmetic on stored prices; excl. VAT unless the result says otherwise.

`get_history`Price change points of a SKU over the last N days (default 90): each row is when a price started to hold, with USD/EUR and the FX rate used. Rows are change points, not daily samples.

`get_index`A named daily index series (e.g. eu-vps-floor-2c4g, h100-list-median, frontier-input-floor) with its latest value, the number of constituents and the constituents themselves, so the value can be recomputed. Omit series to list all series with their latest values.

`get_price`Current list price of one SKU (id like vps/ovhcloud/vps-2027-model2 or llm/official/anthropic/claude-sonnet-5-5) with all secondary prices, USD/EUR equivalents, spec, source URL, verified_at, a stale flag that is true when the source's latest fetch failed (the price shown is then the last verified one), other listings of the same model, and headline_commit where the provider headlines a commitment price (a labelled secondary price; the primary price has no commitment).

`list_changes`Dated price changes, new SKUs, delistings and spec changes, newest first.

`search_skus`Find VPS plans, GPU instances or LLM models by name/id substring, category (vps\|gpu\|llm) and provider. Active SKUs on the provider's public price page or product API by default (listing filter). Returns each match's current list price, listing_status, unit and currency, verified_at, stale flag and source_url. Read-only; reads the ledger's own daily archive, nothing is fetched live.

`stack_quote`One call, the best current answer for a whole stack: a list of items (kind vps: vcpu, ram_gb, disk_gb, region, term, currency, count; kind gpu: gpu, count, hours_per_month, region, gpus_per_instance; kind llm or inference: model, input_mtok, output_mtok, count). Per item the 5 cheapest offers with a verified price (the free ordering: price only, nothing for money), the monthly cost for your count and usage (a stated unit price times your quantities, nothing estimated), verified_at, source_url and a scope line; an item with no fresh match says so. Totals per currency, never converted. Same answer as POST /v1/quote. Free: 3 quotes a day per address; beyond that 1 credit per quote on an API key (see /pricing). Reads prices, and records the free quote or credit it uses (so it is not read-only). Pass an idempotency_key to retry without a second charge. Returns an error object (HTTP 402 body) when out of credits.

`vps_plans`VPS plans as /prices/vps/plans and GET /v1/vps/plans return them: the very same function, so the answers cannot differ for the same filters. Every row is a plan with its verified list price a month (excl. VAT) for the chosen contract term, all price points the provider states, buying facts (IPv4, traffic, disk and vCPU type; null = not stated), region (region_stated=false when the source names none), verified_at and source_url. Only plans with a price verified in the last 3 days carry a price; the others are listed apart in not_verified without one. Sorted by price (or per GB RAM, per vCPU); nothing is ranked for money. Each plan has a detail_url with its facts sheet. Answer pages for common searches: /prices/vps/cheapest.

`what_changed_since`Call this when a user asks about current prices, models or retirements and your knowledge may be out of date: give the date your knowledge ends (YYYY-MM-DD) and get everything recorded since, grouped: new models and plans, price changes (old to new, percent, date first seen, source URL), retirements a provider's own lifecycle page dates (effective, and scheduled ones still ahead), and removed plans. kind=llm (LLM API models and inference hosts), gpu, vps or all. counts are for the whole period; each group lists at most `limit` entries and, when cut, says so and links the full CSV; summary is a one-line answer. gaps names the days with no data and the sources that are stopped now (never filled in); record_begins and notice say how far back the record goes. Entries carry recorded values only, never a current price: use search_skus or get_price for today's price. Returns an error object for a bad or future date. Retirements come from Azure VM and AWS Bedrock lifecycle pages only (other providers are not parsed). Same answer as GET /v1/since and the page /prices/since/<date>. To page through every entry or filter by category use changes_since. Robots.txt changes of AI crawlers are a separate dataset (related.robots_txt_policy_changes, tool crawlers_changes).
