Pay-per-call employee data API on Base, settled in USDC via x402 at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data (specifically employee record 103) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. Payment is handled entirely through the x402 protocol's X-PAYMENT header, meaning callers attach a signed USDC payment to each request rather than managing subscriptions or API keys.
Documentation on the site is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data returned after payment is unknown from the available material.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The actual data returned is completely unknown, making this effectively a stub listing.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content
- —No OpenAPI or schema definition for request or response payloads
- —Unknown what fields or data the employee/103 endpoint actually returns
- —This is a single hardcoded employee ID (103); unclear if other IDs are supported or how to discover them
