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/127` returns JSON data for employee ID 127 when a valid USDC micro-payment is submitted on the Base network. The endpoint accepts POST requests and requires an X-PAYMENT header containing the x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is made in USDC (contract 0x8335…2913) on Base L2, with no API keys, no rate limits, and no minimum commitments required. The x402 challenge advertises a maxAmountRequired of 20000 base units, which equals $0.02 USD (USDC uses 6 decimals).
The exact schema of the employee data returned is not documented in the available crawl material. The docs, pricing, and API pages all appear to require wallet connection and provide no additional detail beyond the landing page. As a result, the response format and available fields for this employee endpoint must be inferred — it likely returns standard employee record fields (name, ID, department, etc.) in JSON, but this is unconfirmed.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented response format, no examples, and all docs/pricing/API pages only show a wallet-connect prompt with no substantive content. The specific employee endpoint is not mentioned on the landing page, making its purpose largely inferred.
Warnings
- —No response schema or example response documented for /api/v1/employees/127
- —The /docs, /pricing, /api, and /README pages all return only a 'Connect wallet' prompt with no useful documentation
- —The employee endpoint is not listed among the advertised APIs on the landing page — its purpose and data format are unknown
- —Output schema in the x402 challenge only specifies HTTP POST method; no field-level schema provided
