    DETAILS ↗

50% off list, already applied above — the wire amounts are pinned in x402-prices.json ↗. Client and full semantics: AGENT-GUIDE §F ↗. Never sign an amount you didn't pin; never re-sign after an uncertain outcome.

02 / PIN → SIGN → RETRY

One challenge, one signed authorization, one retry. Review the pinned source before running its tools.

Step 1 is free. Step 2 signs one EIP-3009 USDC authorization on Arc.

[FINANCIAL EXECUTION]

This one spends. Pin the seller from the repo and never from the challenge, pin the amount from x402-prices.json ↗, and never re-sign after an uncertain outcome — a timeout is not proof of failure, so reconcile before paying again.

The primary interface needs none of these: call the endpoint unpaid, and the 402 response itself carries the full machine-readable offer.
