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/72` returns JSON data for employee ID 72 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 numerous pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request. Payment is settled in USDC (contract 0x8335…2913) on Base L2, with no API keys, no rate limits, and no upfront commitments required. The x402 challenge advertises a maxAmountRequired of 20000 base units, which equals $0.02 USD (USDC uses 6 decimals).
Note that while the landing page lists many endpoint categories, the specific `/api/v1/employees/{id}` path is not listed among them, and no documentation or schema for the employee data response was found. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content. As a result, the exact shape of the employee record returned is unknown and must be discovered by making a paid request.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no response examples, and no documentation beyond a wallet-connect prompt. The specific employees endpoint is not even listed on the provider's own landing page, making its purpose and response format entirely opaque.
Warnings
- —No documentation available — docs, pricing, and API pages all return only 'Connect wallet' with no content.
- —The /api/v1/employees/{id} path is not listed among the provider's advertised endpoints, raising questions about its intended use.
- —No response schema or example data is available; the shape of the returned employee record is unknown.
- —No OpenAPI spec or ai-plugin manifest found.
