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 49) via a POST request. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint uses the x402 "exact" payment scheme, meaning each call requires a one-time micropayment before the server returns data.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (`/api/v1/employees/49/salary`) is not prominently advertised on the site's landing page, and no documentation, request schema, or response schema is published for it. The response MIME type is `application/json`, but the exact fields returned are unknown.
Because no OpenAPI spec, request body schema, or example responses are available, agents calling this endpoint will need to discover the expected input format through experimentation. The 402 challenge was successfully captured, confirming the endpoint is live and accepting payment challenges with a 300-second timeout.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the specific employee salary endpoint is not listed on the site's landing page. Effectively a stub with confirmed liveness.
