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 data for a specific employee (ID 94) via a POST request. It is part of a broader platform offering dozens of pay-per-call 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 via the x402 protocol: callers include an X-PAYMENT header with a signed payment proof, and the server validates it before returning the JSON response. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-use.
Note that this specific endpoint (`/api/v1/employees/94/salary`) is not listed on the provider's public landing page, which focuses on analytics, AI, finance, and utility APIs. The endpoint's purpose — retrieving salary information for a particular employee — is unusual for a public API and the response schema is undocumented. There is no OpenAPI spec, no detailed documentation, and the docs/pricing/README pages all render only a wallet-connect prompt with no substantive content. Buyers should treat this as a minimally documented endpoint with uncertain data provenance.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base), but there is no OpenAPI spec, no response schema, no documentation beyond a wallet-connect stub, and the specific endpoint is not listed on the provider's own landing page. Data provenance and response format are entirely unknown.
