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 #24) via a pay-per-request x402 payment model. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) 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 x402 payment header.
The provider, lowpaymentfee.com, hosts a broader suite of APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/employees/24` endpoint. The exact schema of the employee record returned is not documented in the crawled material, so the response structure must be discovered by making a paid call.
The endpoint is live and returned a proper 402 challenge during probing. Documentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example requests or responses, and no description of what fields the employee object contains.

Quality
The endpoint is live and returns a valid 402 challenge, but there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty. The purpose of the employee data endpoint is unclear beyond its URL path. Effectively a stub listing.
Warnings
- —No OpenAPI or schema documentation available — response structure is unknown
- —All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content
- —The specific employee record (#24) suggests a demo or sample endpoint rather than a general-purpose API
- —No information on what fields the employee object contains or what POST body is expected
