# Synthetix Mainnet

> Developer documentation for Synthetix perpetual contracts

## Integration essentials (for AI agents)

These notes summarize concepts that repeat across the API reference below. **Links in this file use absolute URLs** so tools can fetch pages without resolving a base path.

- **Trader documentation** (separate site): [docs.synthetix.io](https://docs.synthetix.io) — end-user guides; **this** file indexes **developer** integration docs only.
- **Mainnet endpoints** (see [Environments](https://developers.synthetix.io/environments)): **REST:** `POST` `https://papi.synthetix.io/v1/trade` (authenticated), `POST` `https://papi.synthetix.io/v1/info` (public). **WebSocket:** `wss://papi.synthetix.io/v1/ws/trade` (authenticated), `wss://papi.synthetix.io/v1/ws/info` (public). **Headers:** every REST and WebSocket request must send a descriptive **User-Agent** (see Environments).
- **Authentication**: trading uses **EIP-712** signed requests; each request needs a monotonically increasing **nonce**. EIP-712 **domain** for mainnet: `name: "Synthetix"`, `version: "1"`, `chainId: 1`, `verifyingContract: "0x0000000000000000000000000000000000000000"`. See [Authentication](https://developers.synthetix.io/developer-resources/api/authentication) and [Nonce management](https://developers.synthetix.io/developer-resources/api/authentication/nonce-management).
- **REST vs WebSocket**: most actions are available on both; see [REST API](https://developers.synthetix.io/developer-resources/api/rest-api) and [WebSocket API](https://developers.synthetix.io/developer-resources/api/ws-api).
- **Shared types and policies**: [Objects](https://developers.synthetix.io/developer-resources/api/objects), [Notation](https://developers.synthetix.io/developer-resources/api/notation), [Error handling](https://developers.synthetix.io/developer-resources/api/error-handling), and [Rate limits](https://developers.synthetix.io/developer-resources/api/rate-limits).
- **OpenAPI**: there is no public OpenAPI bundle for this API today; the MDX pages listed below are the source of truth.
