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 41) behind an x402 payment wall. The endpoint 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 $0.02 (20,000 base units of USDC with 6 decimals). The provider advertises a flat $0.02/request pricing model across all their API endpoints with no API keys, no rate limits, and instant access. The x402 challenge confirms the endpoint is live and returns a well-formed 402 response with version 1 of the protocol.
The broader lowpaymentfee.com platform hosts multiple API categories including data/analytics, AI/ML (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). However, this specific listing is for the employee salary endpoint, which is not prominently featured on the provider's landing page and its exact response schema is undocumented. The docs, pricing, and API pages behind the site require wallet connection and provide no additional detail.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no documentation on request body format, response schema, or what data is actually returned. The employee salary endpoint is not listed on the provider's own landing page, and all doc/pricing pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
