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 80) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals).
The provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per call with no API keys, no rate limits, and no minimum commitments. However, this specific endpoint exposes what appears to be personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns. No documentation beyond the landing page is available — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" stub with no substantive content.
Because there is no OpenAPI schema, no request/response examples, and no documentation describing the data model or legal basis for serving SSN data, the actual behavior and data authenticity of this endpoint cannot be verified from the available material.

Quality
The endpoint is live (returns a valid 402 challenge), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation. The /docs and other pages are empty stubs. The endpoint purports to serve highly sensitive PII (SSN) with no visible legal or compliance framework, which is a major red flag.
Warnings
- —Endpoint serves what appears to be personally identifiable information (Social Security Numbers). Verify legal compliance (CCPA, GDPR, HIPAA, etc.) before use.
- —No documentation available — /docs, /api, /pricing, and /README pages all return only a wallet-connect stub with no content.
- —No OpenAPI schema or request/response examples are provided; actual endpoint behavior is unverified.
- —Data authenticity is unknown — it is unclear whether this serves real or synthetic/demo employee data.
- —The endpoint is hardcoded to employee ID 80; it is unclear if other employee IDs are supported.
