Pay-per-call HR reviews endpoint on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/hr/reviews/38` is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-call APIs settled via the x402 protocol on the Base network using USDC. The specific endpoint appears to serve HR review data (resource ID 38), though the exact response schema is not documented. The platform advertises a flat $0.02 per request across all its endpoints, with no API keys, no rate limits, and instant access.
The x402 challenge is live and confirms payment of up to 20,000 base units of USDC (0x8335…) on Base, which equals $0.02 (USDC uses 6 decimals). Payment is made via the `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout. The endpoint accepts POST requests.
Note that the specific data returned by this HR reviews endpoint is undocumented — there is no OpenAPI spec, no example response, and no detailed field-level schema available. The broader lowpaymentfee.com site lists many endpoint categories (data/analytics, AI/ML, finance/web3, infrastructure) all at the same $0.02 price point, but individual endpoint documentation is absent. Treat this as a low-documentation, low-cost data endpoint until more details surface.
