Retrieve employee SSN data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee record (ID 141) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The site also offers a broad catalog of other endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same price point.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the response contains beyond the endpoint path implying it returns an SSN for employee 141. The endpoint is live (returns 402 challenge as expected for x402).

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, documentation is essentially nonexistent — no OpenAPI spec, no request/response schema, no examples, and the endpoint path suggests it returns highly sensitive PII (SSN) for a hardcoded employee ID with no explanation of the data source or legitimacy. This is effectively a stub listing.
Warnings
- —Endpoint appears to serve Social Security Number (SSN) data, which is highly regulated PII — verify legal compliance before use.
- —No documentation, OpenAPI schema, or response examples are available; the docs pages only show 'Connect wallet'.
- —Endpoint path is hardcoded to employee ID 141; unclear if other employee IDs are supported or what the data source is.
- —The legitimacy and provenance of the employee/SSN data is completely unknown.
- —No robots.txt or agents.txt present on the origin.
