HR reviews data endpoint on Base, pay-per-call via x402 with USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves HR review data (specifically review ID 1) via a POST request, settling payments in USDC on the Base network. The endpoint is live and returns a standard x402 payment challenge (HTTP 402) when called without payment.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-request APIs spanning data & analytics, AI/ML (sentiment, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payment is made via the x402 protocol using USDC on the Base L2 network.
The specific endpoint `/api/v1/hr/reviews/1` is not listed on the provider's landing page among the advertised API categories, which suggests it may be an unlisted or less-promoted route. The x402 challenge confirms a maxAmountRequired of 20000 base units of USDC (6 decimals), equaling $0.02 per call, consistent with the site-wide pricing. No OpenAPI schema, detailed documentation, or example responses are available for this endpoint, so the exact shape of the returned HR review data is unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation for this specific HR reviews route, no example request/response, and the endpoint is not even listed on the provider's own landing page. Effectively a stub with verified liveness.
