# Deprecated alias for commitment pricing

`GET /v1/custom-index/forward-curve`

## Request

- Base URL: `https://api.liquidcompute.co`
- URL: `https://api.liquidcompute.co/v1/custom-index/forward-curve`
- Auth: API key in header `X-API-Key`

> **Deprecated.**

Use GET /v1/custom-index/commitment-pricing instead. This alias returns
the same recent negotiated rates by contract length, with the same
index-scope and private-txns entitlements, included with Enterprise.
It does not price future delivery windows.
