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 189) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a max amount of 20,000 base units, which equals $0.02 USD (USDC uses 6 decimals). No API keys or rate limits are required — access is gated purely by the x402 payment protocol.
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. Documentation pages exist but were largely empty at crawl time (showing only a "Connect wallet" prompt), so there is no detailed schema or example response available for this specific endpoint. The endpoint is confirmed live, returning a valid x402 challenge on POST.
This particular endpoint raises significant concerns: it purports to serve personally identifiable information (an employee's SSN). Consumers should exercise extreme caution and verify the legality and legitimacy of accessing such data before making any payment. The data returned may be synthetic/demo data, but this cannot be confirmed from available documentation.

Quick start

-H "Content-Type: application/json"Endpoint
Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially absent (all doc pages show only 'Connect wallet'). No request/response schema, no examples, and the endpoint serves PII (SSN data) with no explanation of data provenance or legitimacy. Significant regulatory and ethical concerns lower the score further.
Warnings
- —Endpoint purports to serve personally identifiable information (Social Security Numbers). Accessing or purchasing such data may violate federal and state privacy laws (e.g., GLBA, state SSN protection statutes).
- —No documentation available — all doc/pricing/README pages returned only a 'Connect wallet' prompt with no substantive content.
- —Data provenance is unknown: it is unclear whether the SSN data is real, synthetic, or demo content.
- —No request body schema or response schema is documented; consumers cannot verify what is returned before paying.
- —The endpoint path is hardcoded to employee ID 189 — unclear if other IDs are supported or if this is a demo record.
