x402-gated employee salary endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com exposes an employee salary resource (`/api/v1/employees/134/salary`) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).
The broader lowpaymentfee.com platform advertises a catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services—all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific employee salary endpoint probed here does not appear in the site's public catalog, and no documentation, request schema, or response schema is available for it. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content.
Because there is no OpenAPI spec, no request/response examples, and no documentation describing what this endpoint actually returns or what inputs it expects, the practical utility for an agent is limited. The endpoint is confirmed live (402 challenge captured), but the lack of any schema or sample data means callers must discover the interface by trial and error.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation, no OpenAPI spec, no request/response schema, and the endpoint path (employees/134/salary) does not appear in the provider's own catalog. Effectively a stub listing.
