Tool | Description | Credits |
| Convert a webpage URL to clean markdown with quality score | 1 |
| Convert raw HTML string to markdown | 1 |
| Start crawling a documentation site (path-bounded BFS) | 1/page |
| Check crawl job progress | 0 |

convert_url
Convert any webpage to clean CommonMark markdown:
"Convert https://docs.stripe.com/api/charges to markdown"
Returns the markdown content plus a quality score (0-100) indicating extraction confidence. Scores below 40 indicate the page likely needs JavaScript rendering.
convert_html
Convert HTML you already have — API responses, scraped content, generated markup:
"Convert this HTML to markdown:
<h1>Title</h1><p>Content</p>"
crawl_start → crawl_status → crawl_download
Crawl entire documentation sites:
"Crawl https://docs.example.com starting from /guides/ and get all pages as markdown"
The crawler runs a path-bounded BFS, converting each page. Use crawl_status to check progress and crawl_download to get all pages concatenated with separators:
--- Page: guides/getting-started.md ---
# Getting Started
Content here...
--- Page: guides/authentication.md ---
# Authentication
Content here...Export formats: raw-md (default), langchain (JSONL for LangChain), llamaindex (JSON for LlamaIndex).
