​
Overview

The Agent API supports optional pay-per-request pricing using the x402 protocol. When enabled, agent routes require a payment header before processing.
x402 payments are disabled by default. They are an opt-in feature for API operators.

Payment Network

  • Network: Base mainnet (EIP-155 chain ID 8453)
  • Facilitator: https://www.x402.org/facilitator

​
How It Works

  1. Client sends a request to a priced endpoint
  2. Server responds with HTTP 402 and payment details
  3. Client pays via the x402 facilitator
  4. Client retries the request with the payment proof header
  5. Server verifies payment and processes the request

​
When Disabled

When x402 is not enabled (default), agent routes work normally with standard API key authentication and tier-based access control.
