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 (employee ID 59). It is part of a broader platform offering various pay-per-request APIs across data analytics, AI/ML, finance, and utility categories, all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each request is individually paid.
The platform advertises a uniform $0.02/request pricing model across all its endpoints. The x402 challenge confirms the endpoint is live, returning a proper 402 Payment Required response with payment parameters including the payTo address and the USDC asset contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). Note that this endpoint specifically serves sensitive personally identifiable information (SSN), which raises significant regulatory and ethical concerns regarding data handling, consent, and compliance with laws such as the Privacy Act, GDPR, and various US state privacy statutes.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI schema, no documentation of request/response format, no example payloads, and the crawled docs/pricing/API pages are empty (just 'Connect wallet'). The endpoint serves highly sensitive PII (SSN) with no visible compliance or authorization framework documented.
Warnings
- —This endpoint serves Social Security Numbers — highly regulated PII. Ensure compliance with applicable privacy laws (Privacy Act, state breach notification laws, GDPR, etc.) before use.
- —No documentation, request schema, or response schema is available beyond the x402 challenge metadata.
- —The specific employee ID (59) is hardcoded in the URL; it is unclear whether other employee IDs are available or how authorization/consent is managed.
- —Docs, pricing, API, and README pages all returned only 'Connect wallet' with no substantive content.
