What it does

This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee record (ID 130) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per call (maxAmountRequired of 20,000 base units with 6 decimals = $0.02), matching the site-wide flat pricing.

The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. The specific endpoint probed here (`/api/v1/employees/130/ssn`) is not listed on the provider's public landing page among the advertised API categories, which raises questions about its intended audience and the nature of the data returned.

The x402 challenge was successfully captured (HTTP 402 with a valid x402 version 1 payload), confirming the endpoint is live. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. No OpenAPI schema, detailed documentation, or example responses were found in the crawl. The docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.

Quality

0.35/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation, no example request/response, and the endpoint is not listed on the provider's own landing page. The sensitive nature of SSN data with zero compliance documentation is a significant concern.

Warnings

  • —This endpoint serves Social Security Number data, which is highly regulated PII (subject to FCRA, state privacy laws, etc.). No compliance, authorization, or data-source documentation was found.
  • —The /api/v1/employees/130/ssn path is not listed among the provider's publicly advertised APIs, raising questions about its legitimacy and intended use.
  • —No OpenAPI schema, example responses, or meaningful documentation available — docs/pricing/API pages all return only a 'Connect wallet' prompt.
  • —The data returned by this endpoint could be synthetic/demo data; there is no way to verify authenticity from available materials.
