The independent gate before a merge, deploy, or payout. Deterministic JavaScript (Node) or Python 3 run against a contract or claim; returns HELD, BROKE with the failing input, FINDINGS, or DROP. BROKE requires a contract. Ephemeral sandbox, nothing stored. 0.001 USDC; allow up to 120s.

x402-paid recovery for a coding-agent stuck in a retry loop. Use when retries stop producing: repeated edits, unchanged errors, repeated test failures, or the same hypothesis returning. Returns the loop diagnosis, the exhausted frame, the hidden variable, and the next action — the structural read you can't reach from inside the loop. No account, no session, nothing stored.

x402-preflight: confirm your wallet can transact, and see your balance, in one certified call. Pay $0.01 USDC on Base, get a signed on-chain-anchored receipt. The safe first transaction before you ship real volume.
