x402-gated employee salary endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com exposes an employee salary resource at `/api/v1/employees/125/salary` behind an x402 payment challenge. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 0.02 USDC per request (20,000 base units at 6 decimals).
The provider, lowpaymentfee.com, operates a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. However, the specific `/employees/125/salary` endpoint is not listed on the provider's public landing page among the advertised API categories. Its purpose appears to be retrieving salary information for a specific employee record (ID 125), but no documentation, request schema, or response schema is available beyond the x402 challenge metadata.
Because there is no OpenAPI spec, no example responses, and no documentation for this particular endpoint, the actual data returned and the expected POST body are unknown. The endpoint is confirmed live (402 challenge captured successfully), and the pricing is clear. Agents should be aware that this endpoint's functionality is opaque — it may be a demo, test, or internal resource rather than a production data service.

Quality
The endpoint is live and the x402 challenge is well-formed with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation for this specific endpoint, and it is not listed among the provider's advertised APIs. The endpoint's actual functionality is unverifiable.
