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 39) 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 the response.
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/39/salary) is not prominently advertised on the site's landing page, and no documentation or response schema is provided for it. The response format is declared as application/json, but the exact fields returned are unknown.
Because there is no OpenAPI spec, no example responses, and no dedicated documentation for this endpoint, the actual data quality and structure remain uncertain. The site's docs, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. Buyers should treat this as a lightly documented endpoint and test with a single paid call before relying on it in production.

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 example responses, and no meaningful documentation. The endpoint path (employees/39/salary) is not listed on the site's public catalog, and all doc pages render only a wallet-connect prompt.
