openapi: 3.1.0
info:
  title: GPU Pricing API
  description: |2-

        **GPU Pricing API** provides real-time and historical pricing data
        for GPU compute across 50+ cloud providers and GPU marketplaces.

        ## Features
        - Search current prices across vendors
        - Historical price trends
        - GPU transaction data
        - **Informational Price Index** — EWMA-smoothed composite indices by GPU family, region, and contract type
        - **Transaction Price Index** — smoothed indices derived from verified GPU transactions
        - **Custom Index** — EWMA-smoothed H100 sub-model indices by region, contract type, and vendor category
        - Global region coverage (US, EU, APAC)
        - GPU availability tracking
        - Scope-based API key access control

        ## Authentication
        Send your token as a Bearer token in the `Authorization` header on every request:
        ```
        Authorization: Bearer YOUR_TOKEN
        ```
        Example:
        ```bash
        curl -H "Authorization: Bearer $TOKEN" "https://data-api.compute-index.com/v1/vendors"
        ```
        Tokens are issued by Compute Index (david@compute-index.com); long-lived, treat as secrets.

        > The legacy `X-API-Key` header is deprecated — use the `Authorization: Bearer` header above.
