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 67) behind an x402 paywall. The endpoint accepts POST requests and is settled in USDC on the Base network. The x402 challenge confirms the endpoint is live and requires a maximum payment of 20,000 base units of USDC (0.02 USD, i.e., two cents per request).
The provider site lowpaymentfee.com hosts a broad catalog of pay-per-call 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 personally identifiable information (an employee's SSN). No documentation, input schema, or sample responses are available beyond the x402 challenge and the landing page. The docs, pricing, and README pages all render only a "Connect wallet" prompt with no further content.
Because this endpoint purports to serve Social Security Numbers — highly sensitive PII regulated under numerous privacy and data-protection laws — extreme caution is warranted. There is no documentation explaining the data source, authorization model, or legal basis for serving this data. Buyers should perform thorough due diligence before calling this endpoint.

Quality
The x402 challenge is live and confirms pricing and network, but there is zero documentation, no input/output schema, no example responses, and the endpoint serves highly sensitive PII (SSN) with no explanation of data provenance or legal authorization. Docs pages are empty beyond a wallet-connect prompt.
Warnings
- —This endpoint serves Social Security Numbers (PII) — accessing or distributing SSNs is heavily regulated under US federal and state law (e.g., GLBA, FCRA, state SSN protection statutes). Verify legal authorization before use.
- —No documentation, input schema, or output schema is available for this endpoint.
- —The data source and legitimacy of the employee records are unknown — this could be synthetic/demo data or real PII.
- —Docs, pricing, and README pages on the provider site contain no meaningful content beyond a wallet-connect prompt.
- —The endpoint is hardcoded to employee ID 67; it is unclear whether other employee IDs are supported or what the broader API surface looks like.
