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 120) via the x402 payment protocol. It is part of a broader platform offering pay-per-request APIs across data & analytics, AI/ML, finance/Web3, and infrastructure categories — all priced at $0.02 per call, settled in USDC on the Base network.
The specific resource `/api/v1/employees/120` returns JSON (MIME type application/json) and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network, using the USDC contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. The endpoint advertises a maximum timeout of 300 seconds.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /README) appear to require a wallet connection and contain no substantive content in the crawl. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the employee record contains. The actual data returned by this endpoint is unknown — it could be sample/demo data or a real dataset. Agents should treat this as an opaque JSON resource until further documentation is available.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no example request/response, no documentation of the data model, and the docs/pricing/README pages are empty behind a wallet gate. The purpose and content of the employee record is entirely unknown.
Warnings
- —No OpenAPI or schema documentation available — response structure is unknown
- —All documentation pages (/docs, /pricing, /README) are gated behind wallet connection and returned no content
- —The nature of the 'employee' data is unclear — could be sample/demo data
- —No information on data freshness, accuracy, or source
