x402-payable endpoint returning employee salary data on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data via the x402 payment protocol. The specific resource `/api/v1/employees/52/salary` returns salary information for employee ID 52 when called with a POST request and a valid x402 payment header. Payment is settled in USDC on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of x402-payable APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers simply attach an x402 payment header with each request.
The x402 challenge confirms the endpoint is live and accepts the "exact" payment scheme. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment timeout is 300 seconds. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show "Connect wallet"), so the exact request body format and response schema for this specific endpoint are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and payment details. However, there is no OpenAPI schema, no documented request/response format, and all documentation pages are empty stubs. The purpose of the endpoint (employee salary data) is only inferable from the URL path; no examples or field descriptions exist.
Warnings
