Tools and web search
Grant tools per-agent via checkboxes. Only models with tool-calling support can use them.
1. Granting tools
Open the agent editor. In the Tools tab, check the boxes for the tools you want the agent to use. Tools are granted per-agent — different agents can have different toolsets. You can change grants any time; the next turn applies the new set.
2. Available tools
Platform tools are small utilities built into every agent.
| Tool | What it does |
|---|---|
| echo | Returns the input unchanged. Useful for testing or debug flows. |
| utc_time | Returns the current UTC timestamp and ISO date. |
3. Realtime web search
Enable Realtime Searchto let your agent search the live web when it needs fresh data. The agent decides when to search; turns that don't search cost nothing extra. Each search costs $0.005 via OpenRouter (Exa engine), up to 5 results per search, 10 total per request. Web search only works on models that support tool-calling — see /docs/models to check your model.
