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 128) 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 offers endpoints in categories like data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all at the same price point.
Documentation is extremely sparse. The /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint path suggests it returns personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns around handling of sensitive PII.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no OpenAPI spec, no examples, and the endpoint deals with highly sensitive PII (SSNs) with no visible compliance or authorization framework.
Warnings
- —Endpoint returns employee Social Security Numbers — highly sensitive PII subject to strict regulatory requirements (e.g., CCPA, GDPR, SOX). Verify legal compliance before use.
- —No request or response schema documentation is available; behavior must be discovered empirically.
- —No OpenAPI spec, no example payloads, and all doc pages render only 'Connect wallet' with no content.
- —The endpoint is scoped to a single hardcoded employee ID (128); unclear if other IDs are supported or how to discover them.
- —Provider legitimacy and data source are unknown — exercise extreme caution with any PII returned.
