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/2/salary` returns salary information for employee ID 2 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 per call. No API keys or rate limits are advertised; access is granted immediately upon valid x402 payment. The x402 challenge specifies a 300-second payment timeout window.
The provider (lowpaymentfee.com) hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto feeds, and utility services — all at the same $0.02/request price point. However, documentation beyond the landing page is extremely thin: the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available, so the exact request body format and response structure for this salary endpoint are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation, and no example payloads. The docs pages all render only 'Connect wallet' with no technical content. The purpose ('employee salary data') is vaguely described with no detail on what data is returned or what inputs are accepted.
