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/30/salary` returns salary information for employee ID 30, priced at $0.02 per request paid in USDC on the Base network. No API keys or accounts are required — payment is handled inline via the x402 protocol's `X-PAYMENT` header.
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 data, and utility services, all at a uniform $0.02/request price point. The platform advertises no rate limits, no minimums, and instant access. However, documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so the exact request body schema and response format for this specific endpoint are unknown.
The x402 challenge confirms the endpoint is live, accepting POST requests, and settling payments via USDC (contract 0x8335…2913) on Base mainnet. The max amount required is 20,000 base units, which at 6 decimals for USDC equals $0.02. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation for request/response schemas, no OpenAPI spec, and all doc pages are empty stubs. The purpose of the endpoint (employee salary data) is only inferable from the URL path; no actual examples or field descriptions exist.
Warnings

- —Request body schema and response format are completely unknown; no OpenAPI or examples provided.
- —The endpoint path suggests employee salary data but this is inferred solely from the URL; no description confirms what fields are returned.
- —The broader platform lists many endpoints but none have documented schemas or usage examples.
