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 (employee ID 94) 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 endpoint was live at probe time, returning a well-formed 402 challenge with x402Version 1 and a 300-second payment timeout.
The provider (lowpaymentfee.com) hosts a broad catalog of x402-gated endpoints spanning data analytics, AI/ML inference, finance, and utility services — all at the same $0.02 price point. Documentation pages beyond the landing page returned only a "Connect wallet" stub, so there is no detailed schema documentation for request body parameters or response format for this specific SSN endpoint.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response documentation, no examples, and the docs pages are empty stubs. The endpoint path is hardcoded to a single employee ID (94), and the nature of the data returned is unclear beyond the path name. This is effectively a stub listing.
Warnings
- —This endpoint appears to serve sensitive PII (Social Security Numbers). Consumers should ensure compliance with applicable privacy regulations (e.g., HIPAA, state SSN protection laws).
- —No API documentation is available — docs, pricing, and README pages all return only a 'Connect wallet' stub.
- —The endpoint path is hardcoded to employee ID 94; it is unclear whether other employee IDs are supported or how to discover them.
- —The legitimacy and source of the employee data is unknown. This could be synthetic/demo data.
- —No request body schema or response schema is documented anywhere.
