x402-gated HR document endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com serves an HR document resource (document ID 8) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with the "exact" payment scheme. The per-request cost is 20,000 base units of USDC, which at 6 decimals equals $0.02 USD.
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments. However, this specific listing is for the `/api/v1/hr/documents/8` resource, which appears to be an HR documents endpoint — a category not prominently featured on the landing page.
Documentation is extremely sparse. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's outputSchema stub, and no examples of what the HR document payload looks like. The endpoint is confirmed live (402 challenge returned successfully), but the actual content and structure of the response after payment remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge, confirming pricing and payment details. However, there is no OpenAPI spec, no request body schema, no response examples, and no documentation for what the HR document resource actually contains. The listing is effectively a stub with only payment metadata available.
