Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via a simple POST request, paid per call using the x402 protocol. The specific resource `/api/v1/employees/17` returns JSON data for employee ID 17. Payment is settled on the Base network using USDC (contract 0x8335…2913) with an exact-scheme challenge requiring up to 20,000 base units (i.e., $0.02 per request, since USDC uses 6 decimals).
The provider lowpaymentfee.com hosts a broader suite of APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The x402 challenge was successfully captured (HTTP 402 with valid accepts payload), confirming the endpoint is live. 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 example payloads available.
Because the endpoint path suggests a RESTful resource for a specific employee record and the MIME type is application/json, the response likely contains structured employee data fields (name, role, department, etc.), but the exact schema is unknown. The lack of documentation makes integration speculative beyond the x402 payment mechanics.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payment. However, there is no OpenAPI spec, no request/response schema, no example payloads, and all documentation pages render only 'Connect wallet' with no content. The specific employee data endpoint is not mentioned on the landing page, making its behavior entirely inferred from the URL pattern.

- —Docs, pricing, API, and README pages all render only 'Connect wallet' with no useful content
- —The /api/v1/employees/ path is not listed among the provider's advertised APIs on the landing page
- —Response schema is completely unknown — no example responses available
- —Endpoint may be a demo or test resource rather than a production data source
