Pix to USDT API

Each Pix charge created with POST /deposit can carry the purchase object, with coin, network and destination wallet. After the Pix is confirmed, the purchase runs automatically with the amount received, and you track everything by webhook.

API flow

From the Pix charge to on-chain delivery

The API uses REST and JSON, with JWT token authentication. The most direct flow creates the charge and the purchase in the same call: when the Pix is confirmed and credited in reais, the purchase runs at market price and the crypto goes to the company external wallet.

Step by step:

01 Log in and get the JWT token, valid for 15 days
02 Check assets, networks and limits with GET /crypto/options
03 Create the charge with POST /deposit and the purchase object
04 Your customer pays the Pix and the amount is credited in reais
05 Track by webhook until DELIVERED, with the on-chain hash

Quote

Prefer to lock the price before buying?

If the company already has a BRL balance, POST /crypto/quotes guarantees the price for 30 seconds. Then POST /crypto/purchases runs the purchase with that quote. Requesting a quote and not using it costs nothing. The price already includes the commercial margin, and only the network fee is deducted on delivery.

Ways to buy:

01 In the charge: purchase object in POST /deposit, at market
02 From balance: POST /crypto/purchases, at market
03 With a quote: quoteId valid for 30 seconds
04 Just to show a value: POST /crypto/quotes/estimate
05 Idempotency with externalId, unique per company

USDT and USDC on the main networks

The API supports USDT on Tron, Ethereum, Polygon and Solana and USDC on Ethereum, Polygon and Solana. XGate does not offer custody: there is no crypto balance on the platform, and the crypto goes to the company external wallet, without memo or tag.

Purchase status:

EXECUTING: purchase in progress
PENDING_APPROVAL: under compliance review, when applicable
DELIVERED: crypto confirmed on the network, with txHash
REJECTED: the BRL amount returns to the balance

Integration

Integrate with REST or the official packages

Use the REST API directly or the official packages for Node.js (NPM) and PHP (Composer), which handle login and calls. Before operating, register the allowed IP list and the webhook URL in the dashboard.

The purchase may go through compliance approval before delivery, depending on the account setup, and each company’s limits appear in GET /crypto/options.
