Pay-per-call employee salary data endpoint on Base via x402 (USDC).
What it does
This x402-enabled endpoint at lowpaymentfee.com returns employee salary information for a specific employee (ID 112) via a POST request. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — 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 containing the payment terms, then submit an X-PAYMENT header with a signed payment to the specified address. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.
The specific resource path (`/api/v1/employees/112/salary`) suggests a demo or sample data endpoint rather than a production HR system. The provider's landing page lists this endpoint under "Premium API Access" but does not provide detailed documentation on request/response schemas. The docs, pricing, and API pages behind the site require a wallet connection and yielded no additional content during crawl. Because no OpenAPI spec or response examples were found, the exact shape of the returned salary data is 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 response schema, no request body documentation, and the docs/pricing pages returned no useful content. The endpoint path suggests demo/sample data. Effectively a stub listing.
Warnings
- —No OpenAPI or response schema available — the shape of the salary data returned is unknown.
- —Docs, pricing, and API pages require wallet connection and provided no crawlable content.
- —The endpoint path /api/v1/employees/112/salary with a hardcoded employee ID suggests demo or sample data, not a production API.
- —No information on data source, accuracy, or freshness of employee salary data.
