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/44/salary` returns salary information for employee ID 44 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) at a cost of $0.02 per request.
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/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment via the "exact" scheme.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed documentation for this specific employee salary endpoint. The exact request body format and response structure are unknown and must be discovered by the caller.

However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only 'Connect wallet' with no usable content.
