Answer a question from the web

Answer a question from the web

Searches the web for a question and returns a direct answer or a summary with citations, or JSON that matches an output schema.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.exa.ai
• Endpoint: POST /answer
• Auth: send the header Authorization: Bearer $EXA_API_KEY
• Get a key: https://dashboard.exa.ai/api-keys
• Docs: https://exa.ai/docs/get-started/quickstart

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
