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, gated behind an x402 payment challenge. The specific resource probed is `/api/v1/employees/99/ssn`, accepting POST requests and settling payments in USDC on the Base network.
The x402 challenge specifies a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the `exact` scheme to the specified payTo address, with a 300-second timeout. The endpoint returns JSON and requires no API keys or rate limits — access is granted per-request upon valid payment.
This endpoint is part of a broader platform at lowpaymentfee.com that offers numerous x402-gated APIs across categories including data analytics, AI/ML inference, finance, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint listed here deals with sensitive personally identifiable information (employee SSNs), which raises significant regulatory and ethical concerns. Documentation beyond the landing page is effectively empty (all subpages only show a "Connect wallet" prompt with no further content).

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the docs/pricing/API pages are all blank. The endpoint serves highly sensitive PII (SSNs) with no visible compliance or access controls documented.
Warnings
- —This endpoint serves Social Security Numbers (PII). No compliance documentation (HIPAA, CCPA, GDPR, SOC 2) is visible. Use with extreme caution.
- —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no actual content.
- —No request body schema or response schema is documented — input/output formats are unknown.
- —The legitimacy and legality of an SSN-serving API behind a $0.02 micropayment with no authentication or access controls is highly questionable.
- —No OpenAPI spec or AI plugin manifest available.
