FluSwap

Swap API

No account and no email. FluSwap does not hold the tokens. The wallet in the quote signs the trade and receives the bought tokens. The fee is 1.50% of the amount sold.

Read the chains and the request shape from GET /api/v1. Ask for a quote with POST /api/v1/quote. The response includes the fee and the unsigned steps in route. A blocked quote has no steps. Sign only the steps you have checked.
