Pay-per-call employee salary data endpoint on Base via x402, settled in USDC.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 158) in JSON format. It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, and utility categories. The endpoint accepts POST requests and requires an X-PAYMENT header carrying an x402 payment proof.
Pricing is $0.02 per request, paid in USDC on the Base network (token contract 0x8335…2913). The x402 challenge advertises a maxAmountRequired of 20000 base units; since USDC uses 6 decimals, this equals $0.02. No API keys, rate limits, or subscriptions are required — each call is individually settled on-chain.
Documentation is extremely sparse. The provider's landing page lists many endpoints but the /docs, /pricing, /api, and /README pages all render only a wallet-connect prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific data returned by this employee salary endpoint is unknown beyond the stated mime type of application/json. Treat this as a demonstration or early-stage endpoint until richer documentation appears.

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 beyond a landing page listing, and no examples. The specific data returned is entirely unknown. This is effectively a stub listing.
