x402-paywalled employee salary endpoint on Base, settling in USDC at $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 109) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units, which equals $0.02 USD (USDC uses 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header.
The endpoint is part of a broader API platform at lowpaymentfee.com that offers endpoints across data analytics, AI/ML inference, finance, and utility categories, all priced uniformly at $0.02 per request. The platform advertises instant access with no minimums or commitments.
The specific endpoint `/api/v1/employees/109/salary` is not listed on the provider's landing page among the advertised API categories, which focus on analytics, AI, finance, and infrastructure utilities. It appears to be a demo or sample resource. Documentation pages (docs, pricing, README) returned only a "Connect wallet" prompt with no substantive content, so the request/response schema for this endpoint is unknown beyond the x402 challenge metadata.

Quality
The endpoint is live (returns a valid x402 402 challenge), but there is no OpenAPI schema, no documentation of request/response format, and the specific employee salary endpoint is not listed among the provider's advertised APIs. Documentation pages are empty stubs. The endpoint appears to be a demo resource with minimal practical utility.
