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 48) 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), which equals $0.02 given USDC's 6 decimals. This is consistent with the provider's site-wide pricing of $0.02 per request. The provider advertises no API keys, no rate limits, and instant access — payment is the only authentication mechanism.
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. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. The exact structure of the response payload for this SSN endpoint is unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the endpoint is hardcoded to a single employee ID. The nature of the data returned (SSN) raises significant regulatory and ethical concerns.
Warnings
- —Endpoint serves Social Security Number data — this is highly sensitive PII subject to strict regulations (e.g., GLBA, state privacy laws). Verify legal compliance before use.
- —No documentation, response schema, or example responses are available — the actual response format is unknown.
- —Endpoint is hardcoded to employee ID 48; it is unclear whether other employee IDs are supported or how the broader API is structured.
- —Docs, pricing, and README pages returned no substantive content (only 'Connect wallet' prompt).
- —The legitimacy and provenance of the SSN data served by this endpoint cannot be verified from available materials.
