Pay-per-call HR reviews endpoint on Base via x402, settling in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to an HR reviews resource (specifically review ID 19) via the x402 payment protocol. It is part of a broader platform that offers 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/19` is not listed on the provider's public landing page among the advertised API categories, but it is live and returns a valid x402 402 challenge when probed via POST. The challenge specifies payment of up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 "exact" scheme with a 300-second timeout. No API keys or rate limits are advertised; access is gated purely by micropayment.
Documentation is minimal — the provider's site lists endpoint paths and prices but does not publish request/response schemas, parameter descriptions, or example payloads. The HR reviews category is not mentioned on the landing page at all, so the exact data returned is unclear. The endpoint accepts POST requests and returns application/json according to the x402 challenge metadata.

Quality
