Your first SimpleSwap exchange integration
Choose a pair, request an estimate, and create a tracked exchange.
Start with the catalogue
GET /api/currencies returns the assets and networks on simpleswap.world. Use the symbol as the API identifier and the network label to explain the destination to your user.
Request an estimate
Call GET /api/quote with from, to, amount, and fixed. Read the mode, estimatedAmount, expiresAt, and pricingSource fields for market-referenced quotes.
Create and track
POST /api/exchanges with the selected pair, amount, recipient address, and rate type. Retain the returned exchange ID (e.g. cltlode4kasnva6e) and deposit address, then track status with the same browser session or Bearer key.
