Tracing and analytics
Analytics: requests, errors, latency and tokens
The Analytics page and API: requests, errors, tokens, response time, time to first token, tools, estimated cost and credits.
Reference1 min readUpdated 23 October 2026
Analytics in the sidebar charts your agents over 24 hours, 7, 30 or 90 days, for every agent or one at a time. It is built from the same traces as Tracing, so a spike in a chart can be opened as the requests behind it.
Totals
| Tile | Meaning |
|---|---|
| Requests | Chat requests in the range, from every channel |
| Errors | Requests that ended with an error code |
| Tokens | Input and output tokens together |
| Avg response time | Average end-to-end duration |
| Estimated cost | Estimated model cost, where token prices are available; your provider's bill is the source of truth |
| Credits left | Your balance now |
Charts
- Requests and errors over time, and requests per agent.
- Response time.
- Time to first token, the delay before a reply starts streaming.
- Tools: which tools are called and how often.
Analytics from the API
Three endpoints, all with X-Api-Key and range set to 24h, 7d, 30d or 90d (anything else returns 400 INVALID_RANGE). Per-agent results are bucketed by hour for 24h and 7d, by day for 30d and 90d.
