The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals).\n\nThe provider site 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. The site advertises no API keys, no rate limits, and instant access. However, documentation pages (/docs, /pricing, /README) returned only a \"Connect wallet\" prompt with no substantive content, so there is no schema documentation, example payloads, or response format details available for this specific endpoint.\n\nThis particular endpoint exposes personally identifiable information (an SSN), which raises significant regulatory and ethical concerns. Consumers should exercise extreme caution and ensure compliance with applicable privacy laws (e.g., FCRA, state data-breach statutes) before calling this endpoint.
