The specific resource path `/api/v1/employees/21/ssn` suggests a REST-style lookup of sensitive PII (personally identifiable information) for employee record #21. Payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals = $0.02).\n\nThe provider's landing page advertises 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. The x402 protocol means callers attach an `X-PAYMENT` header with a signed payment proof; no traditional authentication or subscription is needed. The endpoint accepts POST requests and returns `application/json`.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the SSN endpoint actually returns. The nature of this endpoint — exposing SSN data — raises significant regulatory and ethical concerns (PII handling, FCRA compliance, data protection laws). Prospective users should exercise extreme caution.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","pay-per-request","no-api-key","rest-api"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 SSN","micropayment data access","Base USDC API"],"warnings":["Endpoint exposes Social Security Numbers — highly regulated PII.
