Deliver report.md (each client tested, what works, every mismatch with the x402 spec and with IMD's flow, and the smallest adapter that bridges them), the adapter as a small package with tests, and a draft discovery listing for the swarm in the x402 discovery format with a note on how it would be submitted. Test only against a local mock that reproduces the challenge below; never pay. Paid-request flow on https://api.imd.fun (server-side only; browser origins get 403). 1) Make a bearer token: 32 random bytes as hex, header Authorization: Bearer <token>. 2) POST /requests/quote {requestKey: new UUID, action, input} returns {order:{id}} (422 invalid_input lists problems). 3) POST /requests/{id}/submit with no body returns 402 with a challenge: accepts[], quote{id, quoteHash, action, payment{asset, amount, payTo}, expiresAt}, resource, resourceUrl, requesterScopeHash. 4) Check accepts[0] against capabilities and the quote. 5) Sign EIP-712 Permit2 PermitWitnessTransferFrom: domain {name \"Permit2\", chainId 1, verifyingContract 0x000000000022D473030F116dDEE9F6B43aC78BA3}; types PermitWitnessTransferFrom(TokenPermissions permitted, address spender, uint256 nonce, uint256 deadline, Witness witness), TokenPermissions(address token, uint256 amount), Witness(address to, uint256 validAfter); spender = x402 exact Permit2 proxy 0x402085c248EeA27D92E8b30b2C58ed07f9E20001; random 256-bit nonce; deadline at most quote.expiresAt minus 5 s; witness {to: payTo, validAfter: 0}. The payment object is {x402Version: 2, resource, accepted: accepts[0], payload: {signature, permit2Authorization: {from, permitted{token, amount}, spender, nonce, deadline, witness{to, validAfter}}}} with numbers as decimal strings and no extra fields (extra fields fail as invalid_payment_shape). 6) Sign EIP-712 QuoteApproval: domain {name \"IdentityMD Paid Action\", version \"1\", chainId 1}; fields resource string (= resourceUrl), requesterScopeHash bytes32 (0x + value), quoteId string, quoteHash bytes32 (0x + value), paymentHash bytes32 (sha256 of the payment object serialised as key-sorted JSON), action string, asset address, amount uint256, payTo address, expiresAt uint256. 7) POST /requests/{id}/submit again with header PAYMENT-SIGNATURE: base64(JSON payment) and body {quoteSignature}: 202 pending or 200 outcome. 8) Poll GET /requests/{id} with the same bearer until the status leaves quoted, payment_pending and admission_pending. Payment is IMD 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7 on Ethereum mainnet, 0.5 IMD per action (per run for schedules); the wallet needs a one-time IMD approve to Permit2; the server pays gas.
