Pay-per-call HR reviews endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to an HR reviews resource (specifically review ID 8) via a POST request. Payment is settled on the Base network using USDC (contract 0x8335…2913) through the x402 exact-payment scheme. Each call costs a maximum of 20,000 base units of USDC, which equals $0.02 (two US cents) given USDC's 6 decimal places.
The provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, 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 the same $0.02/request price point with no API keys, no rate limits, and no minimum commitments required.
The specific endpoint `/api/v1/hr/reviews/8` is not listed on the provider's landing page among the advertised API categories, and no documentation describes the request body schema or response format for HR review endpoints. The endpoint is confirmed live (returns a valid 402 x402 challenge), but the actual data returned after payment is unknown. The docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional content.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is no documentation for the HR reviews resource, no request/response schema, and the endpoint is not listed among the provider's advertised APIs. Docs pages are empty beyond a wallet connect prompt. Effectively a stub with confirmed liveness.
