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 the x402 payment protocol. The specific resource `/api/v1/employees/75` returns JSON data for employee ID 75 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is handled natively via the x402 protocol: no API keys, no rate limits, and no upfront commitments. The x402 challenge confirms the endpoint is live, accepting USDC (contract 0x8335…2913) on Base with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation on the site is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint's actual data content (what fields an employee record contains) is unknown and must be discovered by making a paid request.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty. The actual data returned is completely unknown, making this effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no content
- —The specific data fields in an employee record are undocumented and must be discovered via a paid call
- —The endpoint path references a specific employee ID (75); it is unclear whether other IDs are supported or how to discover them
