What it does

Arc pre-trade risk in microseconds, no chain call: pass ?hook=0x… and get the verdict read straight out of the Uniswap v4 permission bits encoded in the hook address. It tells you what the hook is ALLOWED to do (run on every swap, rewrite the amounts, touch liquidity), not what it does: permission is not behaviour. No trap rate is quoted - the 83.7% we used to state came from a pre-buy sell quote and was withdrawn on 2026-09-22 after a real round trip sold 10 of 10 pools with that signature.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/51500.json for the price and payment options.
3. Pay. Call GET https://apexfaucet.xyz/api/x402/arc-hook-risk. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, eip155:5042, Solana, eip155:56, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
