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 52) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
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 call. No API keys or rate limits are advertised; access is granted purely via the x402 payment header. The site states "pay only for what you use" with no minimums or commitments.
This specific endpoint is narrowly scoped: it serves SSN data for a single employee record. There is no documentation on request body schema, available query parameters, or the structure of the response beyond the MIME type (application/json). The endpoint's nature — returning personally identifiable information (SSN) — raises significant regulatory and ethical concerns. Prospective consumers should verify that their use complies with applicable privacy laws (e.g., FCRA, state SSN protection statutes, GDPR if applicable).

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation on request/response schemas, no OpenAPI spec, no example responses, and the docs/pricing/README pages are all blank ('Connect wallet' only). The endpoint serves highly sensitive PII with no visible compliance or authorization framework.
Warnings
- —Endpoint returns personally identifiable information (SSN) — verify legal compliance before use.
- —No response schema or example response is documented anywhere.
- —All documentation pages (docs, pricing, README, api) render only 'Connect wallet' with no substantive content.
- —No evidence of security certifications, access controls, or audit logging for PII access.
- —Endpoint is hardcoded to employee ID 52 — unclear if other employee IDs are supported or if this is a demo.
