x402-gated HR reviews endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an HR reviews resource (ID 43) via the x402 payment protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme with no API keys or rate limits required.
The specific endpoint `/api/v1/hr/reviews/43` appears to serve HR review data, though the exact response schema is not documented. It accepts POST requests and returns application/json. The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example request/response payloads, and no description of what the HR reviews endpoint actually returns. The endpoint is confirmed live via the 402 challenge, but the lack of documentation makes it difficult to know what data to send or expect back.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no documentation of request/response schemas, no example payloads, and the docs pages are empty. The purpose of the HR reviews endpoint is only vaguely inferable from the URL path. This is effectively a stub listing.
