Example

cURL


bash
curl https://vindex.ai/api/history?session_id=user-abc-123 \
  -H "X-API-Key: amgai_your-channel-key-here"

JavaScript


javascript
async function loadHistory(sessionId, apiKey) {
    const response = await fetch(
        `https://vindex.ai/api/history?session_id=${sessionId}`,
        {
            headers: { 'X-API-Key': apiKey },
        },
    );

    const { messages } = await response.json();
    return messages; // [{ role, content, created_at }, ...]
}

Python


python
import requests

response = requests.get(
    'https://vindex.ai/api/history',
    params={'session_id': 'user-abc-123'},
    headers={'X-API-Key': 'amgai_your-channel-key-here'}
)

messages = response.json()['messages']
for msg in messages:
    print(f"{msg['role']}: {msg['content']}")

Note: History is tied to the session's conversation window. Sessions expire after 24 hours of inactivity, after which
text
messages
will return empty.
