The Carbon Trading API lets you trade perpetual futures on the SYMM RFQ protocol

Settled on Arbitrum over a normal REST API. Authenticate with a wallet, create an API key, and open, close, and manage leveraged positions with plain HTTP. No smart-contract integration or transaction signing on your side.

In short

1. Authenticate your wallet and create an API key.

2. Delegate trading permissions from a subaccount to that key.

3. Submit an order (POST /v1/trade/create-position) → get a tempId.

4. Poll for the result (GET /v1/positions/open-request/status).

Your counterparty is always a solver that quotes your trade — not an order book. See What is Carbon.
