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/26` 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 26), though the exact response schema and input parameters are not documented in the available crawl material. The endpoint is live and returns a valid x402 challenge when called without payment.
The x402 challenge specifies a maximum amount of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the `exact` scheme with a 300-second timeout. No API keys or rate limits are advertised — access is purely payment-gated. The platform markets itself as offering instant, keyless access across categories including Data & Analytics, AI & ML, Finance & Web3, and Infrastructure, all at the same $0.02 per request price point.
Because the endpoint path references `/hr/reviews/26`, it likely returns structured JSON data about a specific HR review record, but no response schema, sample output, or documentation beyond the generic landing page is available. The broader platform lists many endpoints but provides no OpenAPI spec, detailed docs, or example payloads for any of them.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no response schema, no example payloads, and no documentation beyond a generic landing page. The specific purpose of '/hr/reviews/26' is unclear — it could be sample/demo data. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available for this endpoint
- —The endpoint path '/api/v1/hr/reviews/26' references a hardcoded resource ID; unclear if this is a real dataset or placeholder
- —No sample response or input schema is provided anywhere in the crawl material
- —The broader platform lists many diverse endpoints (AI, finance, geocoding, HR) at identical prices with no docs — provenance and data quality are unknown
