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/64/salary` returns salary information for employee ID 64, 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 a variety of pay-per-call APIs across data analytics, AI/ML inference, finance, and utility categories, all uniformly priced at $0.02 per request. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains or what input the POST body expects. The endpoint's purpose (employee salary lookup) is inferred solely from the URL path and the generic "Premium API Access" description.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no OpenAPI spec, and the docs pages are empty. The endpoint's actual data content is inferred only from the URL path. Effectively a stub listing.

- —Docs, pricing, and API pages all render only 'Connect wallet' with no usable content
- —The purpose of this specific endpoint (employee salary data) is inferred solely from the URL path — no authoritative description exists
