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/51/salary` returns salary information for employee ID 51, priced at $0.02 per request (20,000 base units of USDC on the Base network, where USDC uses 6 decimals). Payment is handled inline via the x402 protocol — no API keys, accounts, or rate limits are required.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all at a uniform $0.02/request price point. The platform settles payments on the Base L2 network using USDC (contract 0x8335…2913). The x402 challenge confirms the endpoint is live and accepting payments with a 300-second timeout window.
Documentation is extremely sparse — the docs, pricing, API, 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's purpose and response format must be inferred entirely from its URL path and the generic "Premium API Access" label.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and documentation pages are empty stubs. The actual data returned is unknown, making this effectively a stub listing.
Warnings
- —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or output schema provided; the response format for salary data is completely unknown.
- —The endpoint path suggests access to individual employee salary records, which may involve sensitive/regulated PII data — verify compliance requirements before use.
- —No request body schema documented; it is unclear what parameters (if any) the POST body should contain.
