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/111/salary` returns salary information for employee ID 111 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913).
The endpoint charges a maximum of 0.02 USDC per request (20,000 base units with 6 decimals), consistent with the provider's site-wide flat pricing of $0.02/request. No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The provider advertises no rate limits and instant access.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data/analytics, AI/ML inference, finance/Web3, and utility services, all at the same $0.02/call price point. 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 detailed documentation for any endpoint, including this one. The actual data returned by this salary endpoint is unknown beyond the declared MIME type of application/json.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation, no OpenAPI schema, no request/response examples, and the docs pages are empty. The purpose and data format of the salary endpoint can only be guessed from the URL path.
