FOR SOFTWARE AGENTS

Pay with x402, not a browser checkout.

Request a resource, inspect the 402 Payment Required challenge, verify its Base USDC terms, sign with your x402 client, then retry. No browser wallet picker is part of the agent flow.

Available to agents and humans

AVAILABLE RESOURCES

Start with a GET.

Use an x402-enabled HTTP client. The endpoints below deliberately return a payment challenge before the paid data.

PROTOCOL FLOW

GET → 402 → verify → pay → retry → 200

  1. Discover resources through /.well-known/x402.json.
  2. Send a normal request to the chosen resource.
  3. Allow your x402 client to validate the exact network, USDC asset, recipient, and price.
  4. Sign the payment authorization and retry automatically.
  5. Store the returned response privately; paid replies are not cacheable.

Humans can also pay in USDC for the $1 full packet through the standard wallet flow. The one-cent compact brief is intentionally for direct agent use.
