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 43) behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated via the x402 protocol on the Base network.
The specific endpoint `/api/v1/hr/documents/43` accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) using the "exact" scheme. The maximum amount required is 20,000 base units of USDC, which at 6 decimals equals $0.02 per request. The platform advertises uniform $0.02/request pricing across all endpoints, no API keys, no rate limits, and instant access.
The endpoint is live and returned a proper 402 challenge during probing. However, documentation is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what the HR document resource actually contains or what input the POST body expects. The endpoint path suggests it retrieves or processes a specific HR document, but the actual payload structure and response format are unknown.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no documentation, no OpenAPI spec, no request/response examples, and no explanation of what the HR document resource actually contains or what POST body is expected. The docs pages are empty beyond a wallet connect prompt. This is effectively a stub listing.
