Agent payments
Integrate x402 pay-per-request and the MPP payment challenge flow. The guide includes request and settlement examples.
Read the agent payment guide →For developers
Payment infrastructure you can inspect before you integrate.
Build stablecoin payment flows with scoped credentials, clear signing steps, and published rail status. Start with the documented route that fits your use case, then verify its current availability.

Cross-chain routes
Request USDC transfer or swap plans, then inspect the selected rail, fees, timing, and required signing steps before execution.
Browse API routes →Scoped API credentials
Create test or live credentials with only the permissions your integration needs. A live key does not enable a payment rail.
Manage API keys →Before you send a payment
- 1. Use a test credential and the documented request schema.
- 2. Check the selected rail and asset against the live status endpoint.
- 3. Verify the amount, recipient, network, expiry, and signature locally.
- 4. Treat a created payment intent as pending until its settlement is confirmed.
Open the developer console
Create a scoped credential and see its environment, permissions, and expiration in one place.
Feature and rail availability varies by deployment and configuration. API credentials do not grant a license, provider account, or authorization to move funds.
