Pay-per-call HR reviews endpoint on Base via x402 — $0.02 per request in USDC.
What it does
This x402-enabled endpoint at `/api/v1/hr/reviews/2` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning data analytics, AI/ML, finance, infrastructure utilities, and more. Each call is settled on the Base network using USDC (USD Coin) at a flat rate of $0.02 per request. No API keys, subscriptions, or rate limits are required — callers simply attach an x402 payment header to each POST request.
The specific endpoint probed (`/api/v1/hr/reviews/2`) appears to serve HR review data, though the provider's landing page does not list it among its featured API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). The x402 challenge confirms the endpoint is live, accepts the `exact` payment scheme on Base, and returns `application/json`. The USDC asset address (`0x8335…2913`) matches the canonical Base USDC contract. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02.
Documentation is minimal — the provider's site offers only a high-level catalog with no request/response schemas, parameter descriptions, or example payloads for any endpoint. The `/api`, `/pricing`, and `/README` pages all resolve to a bare "Connect wallet" prompt with no additional content. Without documentation or sample responses, the exact shape of the HR reviews data returned by this endpoint is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing and asset details, but there is no documentation, no request/response schema, no examples, and the specific HR reviews endpoint is not even listed on the provider's own landing page. Effectively a stub listing.
