Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| 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. |
