What it does

This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee record (ID 93) 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), which equals $0.02 given USDC's 6 decimals. 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 endpoint was live and returned a valid 402 challenge when probed.

The provider (lowpaymentfee.com) hosts a broader catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services — all at the same $0.02 price point. Documentation pages beyond the landing page were effectively empty (showing only "Connect wallet"), so there is no detailed schema documentation for request or response payloads for this specific endpoint.

Quality

The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response documentation, no examples, and the docs pages are empty. The endpoint exposes highly sensitive PII (SSN) with no documented compliance or authorization controls.

Warnings

  • —Endpoint serves Social Security Numbers — highly regulated PII. No compliance documentation (SOC 2, HIPAA, etc.) is visible.
  • —No request or response schema documented; payload structure must be guessed.
  • —All documentation pages beyond the landing page are empty ('Connect wallet' only).
  • —The endpoint is hardcoded to employee ID 93; unclear if other employee IDs are supported or how they are discovered.
  • —No terms of service or data handling policies found.
