HR reviews data endpoint on Base, pay-per-call via x402 with USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to HR review data (specifically resource ID 3) via a pay-per-call x402 protocol. Payment is settled in USDC on the Base network. The x402 challenge confirms the endpoint is live and accepts POST requests, returning JSON responses.
The provider operates a broad catalog of pay-per-request 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 priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.
This specific endpoint (/api/v1/hr/reviews/3) is not listed on the provider's landing page among the advertised API categories, which raises questions about its documentation and intended use. The x402 challenge advertises a maxAmountRequired of 20000 base units of USDC (6 decimals), equaling $0.02 — consistent with the site-wide pricing. No OpenAPI schema, request body documentation, or response examples are available for this endpoint.
