Three endpoints. That's the whole integration.

# 1. Quote — best rate across all liquidity sources
curl "https://api.10fi.org/v1/quote?chain=bsc&from=USDT&to=BNB&amount=100" \
  -H "X-Client-Id: ci_your_client_id" \
  -H "X-API-Key: sk_free_your_key"

# 2. Swap — returns a signable payload (gasless EIP-712 or tx calldata)
curl -X POST "https://api.10fi.org/v1/swap" \
  -H "X-Client-Id: ci_your_client_id" -H "X-API-Key: sk_free_your_key" \
  -H "Content-Type: application/json" \
  -d '{"chain":"bsc","from":"USDT","to":"BNB","amount":"100","userAddress":"0x..."}'

# 3. Submit — relay the signed gasless order; resolver pays the gas
curl -X POST "https://api.10fi.org/v1/submit" -d '{...signed order...}'
