REST API

Read-only, no authentication, rate-limited per IP (120 requests per minute). Every endpoint returns JSON by default and CSV with ?format=csv. Current data and 90 days of history; CC BY 4.0.

Endpoint	Parameters	Returns
`GET /v1/skus`	`category` (vps\|gpu\|llm), `provider`, `q` (substring of id or name), `limit` (≤1000), `offset`, `include_delisted`, `listing` (current\|all\|listed\|catalog_only\|vanished\|unknown; default current)	SKUs with current price, USD/EUR equivalents, spec, source URL, `verified_at`
`GET /v1/skus/{id}`	id = `category/provider/plan`	One SKU plus its other listings (cross-checks)
`GET /v1/skus/{id}/history`	`days` (default 90), or `from`/`to` (ISO dates)	Change points: price, USD/EUR, FX rate used, snapshot id

Only SKUs that are on the provider's public price page or product API count unless `listing` says otherwise; every SKU carries `listing_status` (listed\|catalog_only\|vanished\|unknown), `listing_first_missing` and `listing_reason`
`GET /v1/index`, `GET /v1/index/{series}`	`days`	Named daily series with constituents

Fields

price is the primary price in currency per unit (per_month, per_hour, per_1m_tokens_in). prices holds the secondary prices (per_hour, per_1m_tokens_out, per_1m_tokens_cached_in, per_1m_tokens_in_batch, …) in the same currency. verified_at is the last archived snapshot that contained the SKU; price_since is when the current value was first seen; stale is true when the source's latest fetch failed. Prices exclude VAT unless vat_included is true.

Full history, bulk export and alerts beyond the free window are planned as a paid tier; nothing on the current-data endpoints will move behind it.
