Pay-per-call HR reviews data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com serves HR review data (specifically resource ID 17) behind a micropayment wall. It uses the x402 "exact" payment scheme on the Base network, accepting USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid payment proof to receive the JSON response.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. However, this specific endpoint (/api/v1/hr/reviews/17) is not listed on the provider's public landing page among the advertised API categories. Its exact response schema and the nature of the HR review data it returns are undocumented — the only confirmed details come from the x402 challenge itself, which specifies a POST method, JSON MIME type, and a 300-second payment timeout.
Because no OpenAPI schema, example responses, or dedicated documentation exist for this endpoint, the actual data content and structure remain unclear. The endpoint is confirmed live (returns a proper 402 challenge), but prospective callers should be aware of the lack of documentation.
