Exa API
Give your agents access to Exa API. Bring your own Exa key, or skip the signup and pay per call from your Composio balance with Composio Instant.
Exa is a data extraction and search platform for gathering and analyzing information from websites, APIs, or databases. It helps teams quickly surface insights and automate data-driven workflows.
What is Composio Instant?
Composio Instant lets your agent use paid APIs like Exa without a separate account or API key for each one. New accounts start with $2 of free credit.
No Exa account or key
Your agent calls Exa through Composio, so there is nothing to sign up for, store, or rotate.
Pay per call, at cost
$0.007 per search, paid from your Composio balance with zero markup.

Exa API use cases and example prompts
Copy a prompt into your agent. Each one uses Exa with apps you connect through Composio.
Turn web research into a team brief
Use Exa to find five credible sources on how teams evaluate AI agents. Read the two most relevant pages and add their titles, URLs, and key findings to my Research Tracker in Google Sheets. Post a three-bullet summary with a link to the sheet in Slack's #research channel.
Apps used: Exa, Google Sheets, Slack
Build a knowledge base from official sources
Use Exa Answer to explain how OAuth refresh tokens work. Cite official documentation and include a short example. Save the explanation as a page in my Engineering Handbook in Notion.
Apps used: Exa, Notion
Research accounts and draft outreach
Find Acme's company record in HubSpot. Use Exa to look for recent product announcements on its official website. If you find a relevant announcement, create a Gmail draft that explains why it's a good reason to reach out. Include the source link in a HubSpot note and leave the draft ready for review.
Apps used: Exa, HubSpot, Gmail
Track competitor launches
Create a weekly Exa Search Monitor for product launches from the companies on my watchlist. Send new results to my existing webhook workflow so it can post a digest in #competitive-intel and log each announcement's date, company, and source URL in Google Sheets.
Apps used: Exa, Slack, Google Sheets
Exa API troubleshooting
Still stuck? The Instant tools docs cover limits, charges and session settings.
Pass the URLs to EXA_GET_CONTENTS_ACTION and request text or highlights.
Use Auto Search, request at most 10 results and leave out content add-ons. Connect your own Exa key for the advanced options.
Check its availability in the tools table. If it runs on Instant, check that Instant Toolkits is on for your project, your session allows the action and you use the latest toolkit version.
Your Composio balance is empty. Add funds in Billing if your plan supports it, or connect your own Exa account.
Check credential_source and instant_charge in the Composio execution log.
