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 (ID 43) behind an x402 paywall. It accepts POST requests and settles payments in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The broader lowpaymentfee.com platform offers a variety of pay-per-call API endpoints across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required. However, this specific endpoint is narrowly scoped: it returns SSN information for a single employee record.
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 beyond the x402 outputSchema stub, and no description of what fields the response contains. The endpoint is live (returns a valid 402 challenge), but the nature of the data it serves — personally identifiable information (SSN) — raises significant regulatory and ethical concerns.

Quality
The endpoint is live and returns a valid x402 402 challenge, but documentation is essentially nonexistent — no OpenAPI spec, no request/response schema, no examples. The data served (employee SSN) is highly sensitive PII with no visible compliance or authorization documentation. The listing is effectively a stub with significant regulatory red flags.
Warnings
- —Endpoint serves personally identifiable information (SSN) — ensure compliance with GDPR, CCPA, HIPAA, and other applicable regulations before use.
- —No documentation available beyond the x402 challenge; docs/pricing/README pages all show only 'Connect wallet'.
- —No OpenAPI spec or response schema provided — response format is unknown.
- —No authentication or authorization mechanism described beyond payment; unclear who is authorized to access this data.
- —Endpoint is scoped to a single hardcoded employee ID (43); unclear if other employee IDs are supported.
- —This may be a demo or test endpoint rather than a production data source.
