Person Enrichment Evidence

Choose this endpoint when you need not just raw person data but a signed, auditable evidence artifact — particularly in agentic workflows requiring provenance, compliance documentation, or downstream trust verification. It is preferable over a bare People Data Labs call when you need the result to carry a cryptographic signature and limitation-aware framing that downstream agents or auditors can rely on.

• Person not found in People Data Labs database — returns empty or low-confidence result
• Insufficient identifying information provided — resolution fails without at least one strong identifier
• Rate limits or upstream People Data Labs API errors — service may return a provider error
• Invalid input format (e.g. malformed email or phone) — schema validation failure
• Payment not received or x402 protocol failure — request rejected before processing
