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 (specifically employee record #165) via the x402 payment protocol. It 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).
The provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This specific endpoint falls under what appears to be a sample or demonstration resource (employees/165). The site advertises instant access via the Base network with wallet-based authentication.
Documentation is extremely thin: the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available from the crawl. The endpoint is confirmed live — it returns a proper 402 x402 challenge — but the actual data returned after payment is unknown.

Quality
The endpoint is confirmed live with a valid 402 x402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples of what the endpoint actually returns. The specific resource (employees/165) is not listed on the provider's own landing page catalog, adding uncertainty about its purpose.
Warnings
- —No OpenAPI or schema documentation available — request and response formats are unknown.
- —The /employees/165 path is not listed among the provider's advertised API catalog on the landing page.
- —All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content.
- —Actual response data after payment is unverified; endpoint purpose may be a demo or sample resource.
