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 191) 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 requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authenticate.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. This particular endpoint falls outside those listed categories and appears to serve employee salary data, though no detailed documentation, request schema, or response schema is available beyond the x402 challenge metadata. The output is JSON (mimeType: application/json) and the HTTP method is POST.
Because no OpenAPI spec, request body schema, or example responses were found in the crawl, the exact fields accepted or returned are unknown. The endpoint is confirmed live (402 challenge captured), but callers should expect to experiment with the request body or contact the provider for documentation.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation beyond a generic landing page, and the endpoint's purpose (employee salary for ID 191) is narrow and unexplained. Pricing is clear ($0.02/request in USDC on Base) but everything else must be inferred.
Warnings
- —No request body schema or response schema documented anywhere
- —No OpenAPI or machine-readable spec available
- —The endpoint path suggests access to a specific employee's salary — unclear if this is demo/synthetic data or real PII
- —Documentation pages (/docs, /pricing, /api, /README) all returned only a 'Connect wallet' stub with no useful content
- —Purpose and data source of employee salary information is unexplained
