# API v1

> Legacy Raydium read API at api.raydium.io. Pool / pair / farm / SDK lists. Kept live for clients that have not migrated to API v3.

This is Raydium's original REST API for pools, farms, SDKs, and token data. It continues to serve production traffic and SDK clients but is now considered legacy.

## Host

| Environment | Host             |
| ----------- | ---------------- |
| Mainnet     | `api.raydium.io` |
| Devnet      | Not available    |

## Migration notice

**For new integrations, use [API v3](/api-reference/api-v3/overview) instead.** The v3 endpoints offer:

* Better performance and caching
* Simplified response schemas
* Clearer endpoint organization
* Ongoing feature development
