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 #190) via an x402-gated 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 range of pay-per-call APIs across categories including data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/190) is not explicitly documented on the site's landing page, so its exact response schema and data source are unclear.
The endpoint is confirmed live: it returns a proper 402 challenge with x402 version 1 headers. The payment timeout is 300 seconds. Documentation beyond the landing page is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documented response format, and the /employees/190 path is not mentioned on the site's own landing page. Docs pages are empty beyond a wallet-connect prompt. The actual data returned is unknown.
Warnings
- —The /api/v1/employees/190 endpoint is not listed among the provider's advertised APIs on the landing page — its purpose and data source are unverified.
- —No response schema or example response is available; the shape of returned employee data is unknown.
- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content.
- —The endpoint path suggests it returns a single hardcoded employee record (#190); unclear if other IDs are supported or what the data represents.
