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 36). It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all settled via the x402 protocol using USDC on the Base network.
The endpoint is live and returns a standard x402 402 challenge when called without payment. The price is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is made via the x402 "exact" scheme to the specified wallet address. The endpoint accepts POST requests and returns JSON. No API keys or rate limits are advertised; access is gated purely by micropayment.
The provider site lists many other endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all at the same $0.02 price point. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The nature of the data returned (employee SSN) raises significant regulatory and privacy concerns (PII, potential FCRA/GLBA implications).

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base). However, there is zero documentation on request parameters, response schema, or example payloads. The docs/pricing/README pages are all empty beyond a wallet connect prompt. The endpoint deals with highly sensitive PII (SSN) with no visible compliance or data-source documentation, which is a major red flag.
Warnings
- —Endpoint returns employee SSN data — highly sensitive PII. Verify provider's legal compliance (FCRA, GLBA, GDPR, state privacy laws) before use.
- —No documentation exists for request format or response schema; docs pages render only 'Connect wallet'.
- —No OpenAPI spec or example payloads available — impossible to verify what data is actually returned.
- —The legitimacy and source of the employee data is unknown; could be synthetic/demo data or could raise serious legal issues if real.
- —Hardcoded employee ID (36) in the URL — unclear if other IDs are available or how the broader API works.
