Pay-per-call HR reviews endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to an HR reviews resource (specifically review ID 23) via the x402 payment protocol. It is live and returns a 402 challenge requiring payment in USDC on the Base network. The cost per request is $0.02 (20,000 base units of USDC with 6 decimals). Payment is made via the x402 "exact" scheme to the specified wallet address, with no API keys or rate limits required.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/hr/reviews/23` path. The endpoint accepts POST requests and returns JSON. Beyond the x402 challenge metadata, there is no published OpenAPI schema, request/response documentation, or example payloads available from the provider's site. The docs, pricing, and API pages all appear to require wallet connection and contain no additional technical detail.
Because the endpoint path suggests a single HR review resource (ID 23) rather than a parameterized query, it is unclear whether this is a demonstration endpoint, a fixed dataset, or part of a broader HR reviews collection. Prospective callers should be aware that no input/output schema is documented and the actual response payload is unknown without making a paid request.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, no documentation beyond the landing page listing, and the specific resource (/hr/reviews/23) is not mentioned anywhere on the site. The actual payload and purpose are unknown.
