# Backend API Reference

> REST reference for Gains Network backend services.

Gains exposes two public backend surfaces:

* `backend-global.gains.trade` for cross-chain statistics, personal trading history, contests, dapp helper APIs, campaigns, VIP, and notifications.
* `backend-<network>.gains.trade` for chain-specific trading variables, open trades, rewards, and legacy contest caches.

No authentication is required for public read endpoints. Some write/helper endpoints are intended for the Gains frontend and may enforce rate limits or signature validation.

  Use the generated endpoint pages in this section for parameters, examples, and response schemas.
