x402-gated employee data endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to an employee record (ID 25) behind an x402 payment wall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/25) is not mentioned on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear.
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 spec, no example request/response, and no description of what the employee record contains. Callers should expect a JSON object but will need to discover the schema empirically.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no example responses, and the /employees/25 path is not listed among the provider's advertised APIs. The docs pages are empty. This is effectively a stub listing.
Warnings
- —The /api/v1/employees/25 endpoint is not listed among the provider's advertised APIs on the landing page — its purpose and data source are unverified.
- —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content.
- —No OpenAPI spec or response schema available; callers must discover the response format empirically.
- —The term 'employees' may imply personal data — callers should verify compliance with applicable data protection regulations.
