# Get Twin Chat Evidence

`GET /v3/discovery/twin-chat/{conversation_id}/evidence`

## Request

- Base URL: `https://api.evidenso.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.evidenso.com/v3/discovery/twin-chat/{conversation_id}/evidence`
- Auth: HTTP bearer

Get the conversation-scoped Evidence Trail v2 for a Chat with
Customers conversation.

Returns the cached trail when present, otherwise lazy-builds it
using the persona on the conversation document. Lazy-build does
NOT have access to the original upstream context / mentioned
products — those are only available on the chat-stream call path.
Lazy-built trails surface only the persona's Gold-grounded market
intelligence; connected_nodes and product_context stay empty until
the chat stream rebuilds the trail on a subsequent message.

## Path parameters

- `conversation_id` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
