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 21) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/hr/reviews/21` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed payment of up to 20,000 base units of USDC (i.e., $0.02) to the provider's address on Base. No API keys, rate limits, or upfront commitments are required — each call is independently paid.
The platform's landing page lists categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure, though this particular endpoint falls under an HR/reviews category not prominently featured on the homepage. Documentation pages (docs, pricing, README) appear to require wallet connection and contain no substantive content in the crawl. There is no OpenAPI schema or detailed documentation available for this endpoint, so the exact request body format and response structure are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation, no example request/response, and the docs/pricing/README pages are empty (wallet-gated). The specific purpose of 'HR reviews' is not documented on the site. This is effectively a stub listing.
Warnings
- —No OpenAPI schema or endpoint documentation available
- —Docs, pricing, and README pages are wallet-gated and returned no useful content
- —The HR reviews category is not listed on the provider's homepage — purpose and data format are unclear
- —Request body schema and response schema are entirely unknown
