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 #13) via an x402-gated REST API. The endpoint 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). 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, this specific listing covers only the /api/v1/employees/13 endpoint, which appears to be a sample or demo resource returning employee data.
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 request/response examples, and no detailed field documentation available from the crawled material. The endpoint is confirmed live (402 challenge captured), but the actual response schema and required POST body are unknown.

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 purpose of the /employees/13 endpoint is unclear and may be a demo resource.
