Pay-per-call HR reviews endpoint on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/hr/reviews/36` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs settled via the x402 protocol on the Base network using USDC. The specific endpoint appears to serve HR review data (resource ID 36), though the exact response schema is not documented. The platform advertises a flat $0.02 per request across all its endpoints, with no API keys, no rate limits, and instant access.
The x402 challenge is live and confirms payment of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02) per call. The payment scheme is "exact" with a 300-second timeout. Requests are made via HTTP POST and the response MIME type is `application/json`. The platform also hosts endpoints for analytics, AI/ML inference, finance/crypto data, and utility services, all at the same price point.
Documentation is minimal — there is no OpenAPI spec, no request/response schema beyond the x402 challenge metadata, and the crawled pages beyond the landing page returned only wallet-connect prompts. The actual data returned by this HR reviews endpoint is unknown; callers should expect a JSON object but specifics are not documented.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request body schema, no example responses, and the purpose of the HR reviews endpoint is only inferable from the URL path. Effectively a stub listing.
Warnings

- —The specific meaning of 'HR reviews' and resource ID 36 is undocumented
- —Pages beyond the landing page (pricing, README, /api) returned only wallet-connect prompts with no useful content
