Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns salary information for a specific employee (ID 87) via a POST request. It is part of a broader platform offering dozens of pay-per-call APIs across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.
The endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 protocol: callers receive a 402 challenge with payment details, submit an X-PAYMENT header with a signed USDC transfer on Base, and receive the JSON response upon settlement. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no additional content. The specific input schema for the POST body and the structure of the salary response are not documented anywhere in the available material. The endpoint path suggests it returns salary data for employee 87, but the exact fields, formats, and whether a request body is required remain unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation for the request body, response schema, or what 'employee 87 salary' actually returns. The docs pages are all empty wallet-connect stubs. This is effectively a stub listing.
Warnings
- —No documentation available — /docs, /api, /pricing, and /README all return only a wallet-connect prompt with no content.
- —Input schema for the POST body is completely unknown; no OpenAPI spec provided.
- —Response format and fields are undocumented; the output cannot be verified without paying.
- —The endpoint path is hardcoded to employee ID 87; it is unclear if other employee IDs are supported or if this is a demo.
- —The platform lists many API categories but the specific endpoint under review (employee salary) does not appear on the homepage's API listing, raising questions about its provenance.
