Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/4` returns JSON data for employee ID 4 when called with a valid x402 payment header. 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).
The provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. However, the specific `/api/v1/employees/{id}` endpoint is not listed on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. It accepts POST requests and returns application/json. No OpenAPI spec, detailed documentation, or example responses were found in the crawl — the docs, pricing, and README pages all rendered only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no example responses, and the docs pages are empty. The specific employees endpoint is not listed on the provider's landing page, making its data content and schema unclear. Effectively a stub listing.
Warnings
- —The /api/v1/employees/{id} endpoint is not listed among the provider's advertised APIs on the landing page — its data source and reliability are unknown.
- —No documentation, OpenAPI spec, or example responses are available; docs/pricing/README pages render only a wallet-connect prompt.
- —Response schema for employee data is entirely undocumented — callers cannot know what fields to expect.
