Unauthenticated requests incur a 0.2% (20 basis points) platform fee. Authenticated requests using a JWT token are fee-free – you only pay network gas costs and market maker spreads.
Get your JWT token from the Partner Dashboard for authenticated API access and fee-free swaps.

How to Use Your API Key

Once you have your JWT token from the Partner Dashboard, include it in your API requests: 
curl -X POST https://1click.chaindefuser.com/v0/quote \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{
    "dry": false,
    "swapType": "EXACT_INPUT",
    "originAsset": "nep141:wrap.near",
    "destinationAsset": "nep141:usdt.tether-token.near",
    "amount": "1000000000000000000000000",
    "recipient": "your-account.near",
    "recipientType": "INTENTS",
    "refundTo": "your-account.near",
    "refundType": "INTENTS"
  }'
Store your JWT token securely and never commit it to version control. Use environment variables or secure secret management systems.
