The Swap Aggregator for Stellar

​

What you get

• Best execution across Stellar. Every quote prices the Soroban venues and, when you ask for it, the classic order book. A single trade can split across several pools and hops. See supported venues.
• Gasless trustline. A user who has never held the output asset, and has no XLM to open a trustline, can still receive it in one swap: a sponsor account you control pays for the trustline. See Gasless Trustline.
• Revenue on every swap. Configure a partner fee once on your account. It is collected on-chain and settled to you in USDC each month, with a statement per token. See Fees and revenue share.
• Two ways to execute. Let the API build the transaction for your user to sign, or take the route and execute it from your own Soroban contract. See Quickstart.

​

How to start

1. Register and generate an API key (it starts with sk_).
2. Call POST /quote with the two assets, the amount and the venues you want in protocols.
3. Call POST /quote/build to get the transaction, have your user sign it, and submit it with POST /send.

curl -X POST "https://api.soroswap.finance/quote?network=mainnet" \
  -H "Authorization: Bearer <YOUR_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
