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 79) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The site also hosts a broad catalog of other endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same price point.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The actual data returned by this endpoint (whether it is real PII, synthetic/demo data, or something else) cannot be determined from the available material. Given that the endpoint purports to serve SSN data, consumers should exercise extreme caution regarding legal and regulatory compliance (e.g., FCRA, state privacy laws, GDPR).

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation, no examples, and the nature of the data (real vs. synthetic) is completely unknown. The endpoint deals with highly sensitive PII (SSN) with zero compliance or provenance documentation.
Warnings
- —Endpoint purports to serve Social Security Numbers — highly regulated PII. No compliance, licensing, or data-source documentation is provided.
- —No OpenAPI spec, no request body schema, and no response schema available.
- —All documentation pages (/docs, /pricing, /api, /README) return only a 'Connect wallet' prompt with no usable content.
- —Cannot determine whether data is real, synthetic, or demo. Use with extreme caution.
- —This endpoint is hardcoded to employee ID 79; it is unclear if other employee IDs are supported or how the broader API works.
