Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to employee salary data via a simple POST request. The specific resource `/api/v1/employees/150/salary` returns salary information for employee ID 150, priced at $0.02 per request paid in USDC on the Base network. No API keys or accounts are required — payment is handled inline via the x402 protocol's X-PAYMENT header.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all uniformly priced at $0.02 per request. The platform advertises no rate limits, no minimums, and instant access.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint actually returns. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual response payload structure is unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but documentation is essentially nonexistent — no OpenAPI schema, no request/response examples, no field descriptions. The salary endpoint's actual behavior and output format are entirely unknown. Pricing is clear ($0.02 USDC on Base). Score reflects a live but undocumented stub.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or output schema provided; response format for salary data is completely unknown.
- —The endpoint path suggests demo/sample data (employee ID 150) rather than a production HR system.
- —No information on what request body fields (if any) are expected for the POST method.
