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 129) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (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, crypto, and utility services — all priced uniformly at $0.02 per call. No API keys or rate limits are advertised; access is granted immediately upon valid x402 payment. Documentation pages beyond the landing page are gated behind a wallet-connect flow and were not crawlable.
This specific endpoint exposes personally identifiable information (an employee's SSN). Consumers should exercise extreme caution regarding legal and regulatory compliance (e.g., FCRA, state privacy laws, GDPR) before calling this endpoint. The legitimacy and provenance of the underlying data is unknown from the available material.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and the docs pages are behind a wallet gate. The endpoint exposes highly sensitive PII (SSN) with no visible documentation on data provenance, authorization, or legal compliance, which is a serious red flag.
Warnings
- —Endpoint exposes Social Security Numbers — highly regulated PII. Verify legal authorization before use.
- —No documentation available beyond the landing page; docs, pricing, and API pages require wallet connection.
- —Data provenance and legitimacy of the SSN data is completely unknown from available material.
- —No OpenAPI schema or response examples available — request/response format must be discovered empirically.
- —This may be a demo or test endpoint; the employee ID 129 is hardcoded in the URL path.
