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 (ID 115) 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, with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
The provider site (lowpaymentfee.com) hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint listed here is notably different from the other catalog entries: it exposes what appears to be sensitive personally identifiable information (an employee's SSN). There is no documentation, OpenAPI schema, or example responses available for this endpoint beyond the x402 challenge itself.
Because the endpoint returns a valid 402 challenge with a well-formed x402 v1 payload, it is confirmed live. The payment address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 and the USDC asset contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base mainnet. No further documentation, input schema, or response schema was found in the crawl.

Quality
The endpoint is live (valid 402 challenge), but there is no OpenAPI schema, no request/response examples, no documentation beyond the landing page, and the endpoint exposes highly sensitive PII (SSN) with no visible legal or compliance framework. The crawl pages beyond the homepage returned only 'Connect wallet' stubs.
