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 given employee ID (in this case, employee 145). It is part of a broader platform offering various pay-per-request APIs across data analytics, AI/ML, finance, and infrastructure categories, all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and is gated by an x402 payment challenge. The price is $0.02 per request (20,000 base units of USDC, which has 6 decimals). Payment is made to the specified wallet address on Base, and the response is delivered as application/json. No API keys or rate limits are advertised — access is granted purely through per-call payment.
This is a sensitive endpoint that returns personally identifiable information (PII), specifically Social Security Numbers. The legitimacy and legal compliance of this data source is unclear from the available documentation. The provider's landing page lists many API categories but provides almost no documentation beyond the homepage listing. The docs, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (returns 402 challenge as expected for x402), but documentation is essentially nonexistent — docs, pricing, and README pages all show only 'Connect wallet'. No request/response schema, no examples, and the endpoint serves highly sensitive PII (SSNs) with no visible compliance or legitimacy documentation. This is effectively a stub listing with serious regulatory concerns.
Warnings
- —This endpoint claims to return Social Security Numbers (PII). The legitimacy, legal compliance, and data sourcing of this service are completely undocumented. Use with extreme caution.
- —No documentation is available beyond the homepage listing — docs, pricing, and README pages are empty.
- —No request body schema or response schema is documented; behavior must be inferred entirely from the URL pattern.
- —No evidence of data provenance, consent, or regulatory compliance (e.g., SOC 2, GDPR, CCPA).
- —The endpoint path is hardcoded to employee ID 145; it is unclear whether other IDs are supported or how the API generalizes.
