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 140) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per call (maxAmountRequired of 20,000 base units with 6 decimals = $0.02). No API keys or rate limits are required — access is gated entirely by the x402 payment protocol.
The provider (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. This particular endpoint is narrowly scoped: it serves SSN data for employee ID 140. No documentation beyond the landing page was available (docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content).
Because this endpoint deals with Social Security Numbers — highly sensitive personally identifiable information (PII) — users should exercise extreme caution. The legitimacy, legality, and data provenance of this endpoint are unclear from the available materials. There is no privacy policy, terms of service, or compliance documentation visible on the site.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a landing page, and the endpoint deals with highly sensitive PII (SSN) with zero compliance or provenance information. The docs/pricing/API pages are effectively empty.
Warnings
- —SENSITIVE PII: This endpoint claims to return Social Security Numbers. Legal compliance (FCRA, state privacy laws, GDPR if applicable) is entirely the caller's responsibility.
- —No privacy policy, terms of service, or data provenance documentation found on the provider's site.
- —No response schema or example response available — actual output format is unknown.
- —Documentation pages (/docs, /pricing, /api, /README) returned no useful content beyond a wallet connect prompt.
- —Data legitimacy is unverified — it is unclear whether this endpoint returns real, synthetic, or fabricated SSN data.
