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 166) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The site also offers a broad catalog of other endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same price point.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific behavior of this SSN endpoint (what input it expects in the POST body, what fields the response contains, whether it returns real or synthetic data) is entirely unknown from the available material.
Capabilities

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schema, no examples. The nature of the data (real vs. synthetic SSNs) is completely unclear, and the endpoint path suggests access to highly sensitive PII without any visible compliance or legitimacy information.
Warnings
- —This endpoint purports to return Social Security Numbers (SSNs), which are highly sensitive PII. There is no documentation on data provenance, compliance (e.g., SOC 2, HIPAA), or whether data is real or synthetic.
- —No OpenAPI spec, request schema, or response schema is available — the endpoint's expected input and output are unknown.
- —Documentation pages (/docs, /pricing, /api, /README) are all empty beyond a wallet connect prompt.
- —The legitimacy and legal compliance of an endpoint selling SSN data for $0.02 per request with no authentication or access controls is highly questionable.
