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 56) behind an x402 paywall. It accepts POST requests and is settled in USDC on the Base network. The x402 challenge confirms the endpoint is live, advertising a max amount of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data/analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call with no API keys, no rate limits, and no commitments. This particular endpoint is categorized under employee data access. No OpenAPI schema, request body documentation, or response examples were found in the crawl; the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no further content.
Because this endpoint exposes personally identifiable information (SSN), consumers should exercise extreme caution regarding legal compliance (e.g., FCRA, state privacy laws, GDPR) before calling it. The lack of documentation about data provenance, consent, or access controls is a significant concern.

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 schema, no OpenAPI spec, and the docs pages are empty. The endpoint exposes highly sensitive PII (SSN) with no visible compliance or provenance information, which is a major red flag.
Warnings
- —Endpoint exposes Social Security Numbers — highly regulated PII. Verify legal authorization before use.
- —No documentation found: docs, pricing, API, and README pages all returned only 'Connect wallet' with no content.
- —No request body schema or response schema available — behavior must be inferred entirely.
- —Data provenance and consent mechanisms are completely undocumented.
- —Endpoint path is hardcoded to employee ID 56; unclear if other IDs are supported.
