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 88) when called via POST. It is part of a broader platform offering dozens of pay-per-request API endpoints 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 include an X-PAYMENT header with a signed payment proof, and the server fulfills the request after verifying the on-chain settlement. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-call.
Documentation is extremely sparse. The landing page lists available endpoints and pricing, but the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads. The endpoint path suggests it returns salary data for employee 88, but the exact request body format and response structure are unknown. The platform appears to be a demonstration or early-stage x402 marketplace rather than a production data service.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The docs pages all render only 'Connect wallet'. The endpoint path is oddly specific (employee 88 salary) with no context on what data source backs it. This is effectively a stub listing.
Warnings
- —No API documentation available — /docs, /pricing, and /README pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema for request or response bodies
- —The endpoint path (/employees/88/salary) is hardcoded to a single employee ID with no explanation of the underlying data source
- —The platform appears to be a demo or early-stage project; reliability and data authenticity are unknown
- —No information on data provenance or whether salary figures are real, synthetic, or illustrative
