x402-gated employee data endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an employee record (ID 16) via the x402 payment protocol. It is part of a broader platform offering various pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 micropayments on the Base network using USDC.
The specific endpoint `/api/v1/employees/16` returns JSON data (MIME type application/json) for a single employee resource. Payment is settled on-chain on Base to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The maximum amount required per request is 20,000 base units of USDC (6 decimals), which equals $0.02. The endpoint accepts POST requests and has a payment timeout of 300 seconds.
The platform advertises no API keys, no rate limits, and instant access. However, documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no response examples, and no description of what fields the employee record contains. The endpoint is live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what data to expect in a successful response.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation of the employee data fields, and the docs/pricing/README pages are all empty. The endpoint's purpose (employee record by ID) is only inferable from the URL path.
Warnings
- —No OpenAPI or response schema available — the structure of a successful response is unknown.
- —Documentation pages (/docs, /pricing, /README, /api) contain no substantive content, only a 'Connect wallet' prompt.
- —The specific data returned for an employee record is undocumented; field names and types are unknown.
- —This endpoint serves a single hardcoded employee ID (16); it is unclear if other IDs are available or how to discover them.
