Encrypted at rest, isolated from the model
Resolved from an AES-256-GCM vault at the moment of the call and attached to the request — the model never sees the secrets.

Perform an Exa web search and return results. Takes a query and optional filters for domain inclusion/exclusion, date range, and search type. Returns matching web results with titles, URLs, published dates, and text snippets. Use `autoprompt` from the response to refine or repeat the search.
Extract clean, LLM-ready content from URLs. Returns structured content per URL including text, highlights, and summaries. Supports text, HTML, or markdown output formats.
Get an LLM answer to a question informed by Exa search results. Returns a generated answer text with citations from source URLs. Use for Q&A, research, and fact-finding tasks.
Creates a new Exa agent run. Starts an agent process that works toward a specified goal and returns the run details. Use the returned run ID to check status, list events, or cancel the run.
Retrieves the details of a specific agent run. Returns run status, goal, model, and result if completed. Use to check whether a run has finished or to get its output.
Retrieves a list of agent runs. Returns runs with their current status, goal, and creation timestamps. Use to browse all runs and find specific ones by their IDs.
Cancels an in-progress agent run. Stops the agent's execution and updates the run status. The response includes both the previous and current status.
DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Permanently deletes an existing agent run. This action is irreversible — the run record and all associated data will be permanently removed. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user exactly what will be deleted and that it is permanent, and wait for their explicit written confirmation before proceeding.
Retrieves a list of events for a specific agent run. Returns chronological events including steps, tool calls, and results. Use to monitor run progress or inspect what the agent did.
