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 171) 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 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. This particular endpoint is part of what appears to be an employee data resource. However, the nature of the data returned (SSN) raises significant regulatory and ethical concerns. There is no documentation beyond the landing page describing what fields are returned, what input the POST body expects, or what authorization/compliance framework governs access to this sensitive personally identifiable information.
The endpoint is live and responds with 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 with a valid x402 challenge, but there is zero documentation on request/response schema, no OpenAPI spec, and the crawled docs pages are empty. The endpoint exposes highly sensitive PII (SSN) with no visible compliance, privacy, or authorization framework, which is a major red flag.
Warnings
- —Endpoint returns Social Security Number data — highly regulated PII. No compliance documentation, privacy policy, or data governance framework is visible.
- —No request body schema or response schema documented anywhere.
- —Docs, API, pricing, and README pages are all empty (only show 'Connect wallet').
- —Endpoint is scoped to a single hardcoded employee ID (171); unclear if other IDs are available or how the resource is parameterized.
- —Unknown whether the data is real, synthetic, or demo data — treat with extreme caution.
