What it does

Human Lint is an x402-enabled endpoint that lets you submit a code review request and pay a flat $5 (USDC on Base) per review. The service is gated behind an x402 payment challenge: callers must include an X-PAYMENT header with a valid payment proof to access the endpoint. Once payment is verified, the service processes the code review request and returns a response containing payment confirmation and the code review request details.

The landing page describes the service as "Human feedback for your code, $5 flat" and offers GitHub-based authentication for the web flow. The API endpoint at `/api/payments` accepts POST requests and returns a JSON object with `success`, `payment`, and `codeReviewRequest` fields. Payment is made in USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on the Base network, with a maximum amount of 5,000,000 units (i.e., $5 USDC given 6 decimals).

Documentation is minimal — no dedicated docs, pricing, or API reference pages exist beyond the landing page and the x402 challenge itself. The request body schema is not documented, so callers will need to infer the expected payload (likely code or a pull request reference). The service appears live and functional based on the 402 challenge response.

Fit

Best for

  • —Developers wanting quick human feedback on code changes
  • —AI agents that need human-in-the-loop code quality checks
  • —Teams without dedicated reviewers who want on-demand reviews

Not for

  • —Automated static analysis or linting (this is human review, not tooling)
  • —Free or high-volume code scanning needs
  • —Non-code review tasks

Quality

0.45/ 1.00

The x402 challenge is live and well-formed, confirming the endpoint works and pricing is clear ($5 USDC on Base). However, there is no documentation, no request body schema, and no examples beyond what can be inferred from the output schema and landing page tagline. The request body and detailed response fields are entirely inferred.

Warnings

  • —No API documentation exists — /docs, /api, /pricing, and /README all return 404.
  • —Request body schema is undocumented; the example request is speculative.
  • —Response fields 'payment' and 'codeReviewRequest' are typed only as generic objects with no property details.
  • —It is unclear whether the review is synchronous or asynchronous (likely async given human involvement).
