How this service works
Expand selected business event IDs into dated, versioned primary-source evidence. Use after lead search to verify a small set of results before citing or acting on them.
Output
Returns dated, versioned primary-source evidence records for each requested event ID, including source citations and timestamps that allow the agent to verify and cite specific business changes with confidence.
Example use cases
Example prompt
“I just got back a list of business change event IDs from my lead search — can you pull up the primary-source evidence and dates for these three events: '3fa85f64-5717-4562-b3fc-2c963f66afa6', 'a1b2c3d4-e5f6-7890-ab12-cd34ef56gh78', and 'deadbeef-dead-beef-dead-beefdeadbeef'? I need to verify them before I reach out.”
Technical details
Endpoint
POSThttps://api.businesschanges.dev/v1/events/evidenceWhen to prefer
Use this endpoint after a lead search or business change discovery step, when you have a small set of specific event IDs (1–50) that need verification with primary-source evidence before being cited, shared, or acted upon. Prefer this over a broad search API when you already know the specific event IDs and need authoritative sourcing rather than discovery.
Side effects
- Invalid UUID format returns a 400 validation error
- Array with zero items or more than 50 items returns a 400 out-of-range error
- Unknown or non-existent event IDs may return empty evidence records or 404
- Payment failure (x402) blocks the request before processing
- Partial results if only some event IDs have associated evidence
