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 188) 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 settles payments on the Base network using USDC (USD Coin) via the x402 exact payment scheme.
The price per request is $0.02 USDC (maxAmountRequired of 20,000 base units with 6 decimals). No API keys or rate limits are advertised — access is gated purely by the x402 payment header. The endpoint was confirmed live, returning a 402 challenge with x402Version 1 and a 300-second payment timeout.
Documentation is extremely sparse. The provider's docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains. The endpoint path suggests it returns salary data for employee 188, but the actual response structure is unknown. The provider site lists many endpoints across multiple categories, all at $0.02/request, but provides no further documentation for any of them.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request parameters, response schema, or what data is actually returned. The docs pages are empty beyond a wallet connect prompt. The endpoint path and description are the only clues to functionality.
Warnings

- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no content
- —The specific employee ID (188) is hardcoded in the path; unclear if other IDs are supported or how to discover them
- —Provider offers many endpoints but none appear documented beyond a title and price
