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 44) behind an x402 paywall. It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.
The specific resource `/api/v1/hr/documents/44` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (asset 0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.
The endpoint is live and returning a valid x402 version-1 challenge. However, there is no OpenAPI schema, no detailed documentation for this specific HR documents endpoint, and no example request/response payloads available. The exact contents and structure of the HR document returned are unknown — the endpoint's purpose (HR documents) is only inferable from the URL path. The broader platform lists many endpoint categories but does not provide per-endpoint documentation pages.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documentation for this specific HR documents endpoint, no example request/response payloads, and the actual content returned is entirely unknown. The listing is effectively a stub with confirmed liveness and pricing.
