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 records via a simple POST request, gated by the x402 payment protocol. The specific resource `/api/v1/employees/73` returns JSON data for employee ID 73. 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 — access is granted purely through the x402 payment header.
The provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced at $0.02 per request. However, the specific endpoint being listed here is an employee data resource. The x402 challenge confirms the endpoint is live and accepting payments. Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the exact schema of the employee record returned is unknown.
Because there is no OpenAPI spec, no response schema documentation, and no example payloads available, agents calling this endpoint will need to discover the response format empirically. The endpoint accepts POST requests and returns application/json content.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI spec, no response schema, no example requests or responses, and all documentation pages are empty stubs. The purpose of the specific employee endpoint is only inferable from the URL path.
Warnings
- —No OpenAPI or response schema available — response format is unknown
- —All documentation pages (/docs, /api, /pricing, /README) return only 'Connect wallet' with no actual content
- —The endpoint path suggests a fixed employee ID (73); it is unclear whether other IDs are available or what the full employee schema looks like
- —The broader site advertises many API categories but this specific endpoint is an employee record, which is not listed on the landing page catalog
