File Download Storage and Expiry

Composio file URLs are short-lived staged downloads

When a hosted tool returns a file URL such as data.file.s3url, Composio normally stages the bytes in Composio-managed object storage and returns a signed download URL rather than the provider's original URL.

The default signed-URL lifetime is one hour and can be configured for a project through its File TTL setting. Staged files are cleaned up after 24 hours. URL expiry and file cleanup are separate: rerun the tool or download the file again to obtain a fresh URL.

There is no single customer-facing maximum that applies to every tool. Provider limits, the action implementation, runtime memory, and timeouts can impose lower limits, so check the exact action before quoting a hard cap.
