Pay with x402

Use x402_fetch when the agent should fetch a URL and pay any HTTP 402 challenge automatically. Use x402_pay when the agent already knows the exact USDC price.

Prerequisites

Funded wallet (XLM for fees; USDC for payments)
USDC trustline open (Connect / dashboard if needed)
Policy caps high enough for the payment

Flow

x402_fetch({ url, max_amount_usdc? })
→ Hub pays USDC if challenged → returns response body

Policy caps and optional human confirmation still apply. On confirmation_required, approve in the dashboard and poll await_confirmation. See Payment tools.
