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 the x402 payment protocol. The specific resource `/api/v1/employees/7` returns JSON data for employee ID 7, gated behind a per-request USDC micropayment on the Base network. The x402 challenge confirms the endpoint is live and accepts payments of up to 20,000 base units of USDC (0.02 USD) per call.
The broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no commitments required — payment is handled entirely through the x402 protocol using USDC on Base.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains. The endpoint accepts POST requests based on the outputSchema in the x402 challenge. Without sample payloads or response schemas, integrators will need to experiment to discover the data format.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is zero documentation beyond the landing page listing. No OpenAPI spec, no request/response schemas, no examples, and all doc pages render only 'Connect wallet'. The specific endpoint (/employees/7) is not even listed on the homepage — it appears to be a sample or test resource. Effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —The /api/v1/employees/7 endpoint is not listed among the advertised APIs on the homepage
- —Response format and fields are completely unknown — no examples exist in crawled material
- —Platform appears to be a demo or early-stage project with many advertised endpoints but no substantive docs
