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 #189) via an x402 pay-per-call model. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum charge 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 provider, lowpaymentfee.com, hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance/Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02/request pricing and x402 payment flow on Base.
Documentation 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 spec, no request/response schema documentation, and no example payloads available. The exact structure of the employee data returned by this endpoint is unknown. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes integration speculative.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing, but there is zero documentation on request/response schemas, no OpenAPI spec, and all doc pages are empty. The purpose of the employee data endpoint is unclear beyond the URL path. This is effectively a stub listing.
