# Available Indices

> List only the indices THIS key is authorized for (no cross-client enumeration).

<Info>
  The Intraday Index is available to authorized clients. Your API token must have the required permissions added — contact [david@compute-index.com](mailto:david@compute-index.com) to request access.
</Info>

## Example

List the indices your token can read, their interval ranges, and supported filters (no `index_id` needed):

```bash theme={null}
curl -H "Authorization: Bearer $TOKEN" \
  "https://data-api.compute-index.com/v1/custom-index/available"
```

  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.

        ## Rate Limits
        - **Free tier**: 100 requests/minute, 10,000/day
        - **Pro tier**: 1,000 requests/minute, 100,000/day
        - **Enterprise**: Custom limits

        ## Data Coverage
        - 50+ vendors (AWS, Azure, GCP, Oracle, CoreWeave, Lambda, RunPod, Vast.AI, FluidStack, Vultr, etc.)
        - 30M+ historical pricing records
        - Updated multiple times daily
