HR reviews data endpoint, pay-per-call via x402 on Base with USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to HR review data (specifically resource ID 10) via a pay-per-request x402 protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider (lowpaymentfee.com) hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint sits under the HR reviews path (`/api/v1/hr/reviews/10`), but the provider's landing page does not list it among its advertised API categories, and no documentation, schema, or example responses are available for it. The exact shape of the response payload is unknown.
Because there is no OpenAPI spec, no request/response schema documentation, and the HR reviews endpoint is not mentioned on the provider's own landing page, the listing carries significant uncertainty about what data is actually returned and what input parameters (if any) the POST body accepts. The endpoint is confirmed live (402 challenge captured), but callers should experiment cautiously.

Quality
