The endpoint accepts POST requests and is settled in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.\n\nThe provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This particular endpoint falls outside those listed categories and appears to serve sensitive personally identifiable information (PII). The endpoint is live and returns a proper 402 challenge, but documentation beyond the landing page is essentially empty (all subpages just show \"Connect wallet\").\n\nBecause this endpoint purports to serve Social Security Numbers — highly regulated PII in the United States — consumers should exercise extreme caution. There is no documentation explaining the data source, authorization model, compliance posture, or legal basis for distributing SSNs. The endpoint may be a demonstration, a honeypot, or a test fixture; there is no way to confirm from available materials.","tags":[],"capabilities":["x402-payment","usdc-base","pii-lookup","employee-data","per-request-micropayment","post-method"],"categories":["data","pii"],"synonyms":["SSN lookup","social security number API","employee PII","employee SSN endpoint","x402 data API","pay-per-call PII"],"warnings":["Endpoint claims to serve Social Security Numbers — highly regulated PII under US law (FCRA, GLBA, state privacy laws).
