x402-gated employee salary endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to employee salary data (specifically employee ID 78) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) via the x402 "exact" scheme.
The price per request is 20,000 base units of USDC. Since USDC uses 6 decimals, this equals $0.02 per call, consistent with the provider's site-wide pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge specifies a maximum timeout of 300 seconds.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all at the same $0.02/request price point. However, the specific endpoint being listed here (/api/v1/employees/78/salary) is not documented on the provider's landing page among the advertised API categories. Its exact response schema and the nature of the salary data it returns are unknown. The provider's docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional documentation.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, this specific endpoint is not listed among the provider's advertised APIs, there is no documentation of request/response schemas, and the docs/pricing/README pages are empty beyond a wallet-connect prompt. The purpose and data returned are entirely inferred from the URL path.
Warnings
- —This specific endpoint (/api/v1/employees/78/salary) is not listed among the provider's advertised APIs on the landing page — its legitimacy and data source are unclear.
- —No API documentation exists: docs, pricing, and README pages all show only 'Connect wallet' with no content.
- —No request or response schema is available; the structure of returned salary data is unknown.
- —The endpoint appears to serve data for a hardcoded employee ID (78); it is unclear if other employee IDs are supported or what data is returned.
