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 157) behind an x402 paywall. The endpoint accepts POST requests and is settled 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 provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint exposes what appears to be personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns. There is no documentation beyond the landing page describing what the response payload looks like, what input is expected in the POST body, or what authorization controls exist beyond the payment gate.
The endpoint is live and returns a valid x402 challenge (HTTP 402). No OpenAPI schema, detailed docs, or example responses were found in the crawl. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation of request/response formats, and the endpoint exposes highly sensitive PII (SSN) with no visible compliance or access-control documentation. The crawled docs/pricing/API pages were empty beyond a wallet connect prompt.
Warnings
- —This endpoint appears to serve Social Security Numbers (PII). Exposing SSNs via a payment-only gate with no authentication, authorization, or compliance documentation raises serious legal, regulatory (e.g., FCRA, state privacy laws), and ethical red flags.
- —No request body schema or response schema is documented anywhere.
- —All documentation pages (docs, API, pricing, README) returned only a 'Connect wallet' prompt with no substantive content.
- —The endpoint is hardcoded to employee ID 157 — it is unclear whether other employee IDs are supported or what data is actually returned.
- —No OpenAPI spec or ai-plugin manifest found.
