# Perpetuals API

The Perpetuals API provides market data, account data, signed trading actions, and real-time WebSocket streams for Meridian perpetual futures.

Use the HTTP API for requests and snapshots. Use WebSocket streams for final order results and live changes. Use the Archive API for long-range account and market history.

Select the correct environment from [API Hosts](/protocol-reference/api-hosts). Retrieve the EIP-712 domain from `GET /v1/rpc/config`. Do not hard-code the chain ID or verifying contract.
