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 188) 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, with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
The provider site (lowpaymentfee.com) hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. No API keys or rate limits are advertised; access is granted purely via the x402 payment header. However, documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so there is no schema documentation for request bodies or response formats for this specific endpoint.
This particular endpoint raises significant concerns: it purports to serve personally identifiable information (an employee's SSN). Consumers should exercise extreme caution regarding the legality and ethical implications of purchasing or using such data. The legitimacy and provenance of the data behind this endpoint cannot be verified from the available material.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is zero documentation on request/response schemas, no OpenAPI spec, and the docs/pricing/README pages are all empty. The endpoint serves highly sensitive PII (SSN), raising serious regulatory and ethical red flags that further reduce the score.
Warnings
- —This endpoint claims to serve Social Security Numbers (PII). Accessing, purchasing, or using SSN data may violate federal and state privacy laws (e.g., GLBA, state SSN protection statutes) unless you have lawful authorization.
- —No documentation exists for request body schema or response format — all doc pages return only 'Connect wallet'.
- —Data provenance and legitimacy cannot be verified from available material.
- —The endpoint is hardcoded to employee ID 188; it is unclear whether other employee IDs are supported or if this is a demo/test record.
