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 40) 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/40` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. No API keys, rate limits, or subscriptions are required — access is purely pay-per-use.
Note that the endpoint path suggests it retrieves or interacts with a specific HR review record (ID 40). However, no detailed documentation, request schema, or response schema is available from the provider's site. The landing page lists many endpoint categories but does not include an explicit HR reviews category, so this endpoint may be less documented or experimental compared to the advertised analytics, AI, and finance APIs.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no detailed documentation for this specific HR reviews endpoint, and the landing page does not even list an HR category — making the purpose and data format largely unknown.
