Tools

Functions exposed to the LLM to take actions

NameDescription
crawlB

Crawl a URL and return HTML content. Pass store=true to push the result to Crawlbase Cloud Storage instead of returning the body — the response will then contain only the RID and metadata, which can later be retrieved via storage_get.

crawl_markdownA

Crawl a URL and extract clean markdown content. Pass store=true to persist the original page in Cloud Storage and return only the RID + metadata.

crawl_screenshotA

Take a screenshot of a webpage. Pass store=true to persist the underlying HTML page to Cloud Storage (the screenshot itself is not stored and is still returned as an ephemeral screenshot_url).

storage_getA

Retrieve a single stored page from Crawlbase Cloud Storage by RID or URL. Only works for pages previously crawled with store=true. Returns the raw JSON record by default; pass as=html to return just the body, or as=markdown to convert it.

storage_deleteA

Delete a single item from Crawlbase Cloud Storage by RID.

storage_listA

List RIDs of pages previously crawled with store=true in Crawlbase Cloud Storage. Supports scroll-based pagination (scroll session expires after 15s of inactivity). Returns at most 1000 per call.

storage_countA

Get the total number of documents in Crawlbase Cloud Storage.

storage_bulk_getA

Bulk-fetch up to 100 stored items by RID. Bodies are decoded automatically. Default as=metadata_only returns just RID/URL/timestamps to keep context lean; use as=html or as=markdown to include bodies.

storage_bulk_deleteB

Bulk-delete up to 100 items from Crawlbase Cloud Storage by RID. Irreversible.
