tavily-extract

最大20件のURLからクリーンなマークダウンまたはテキストを抽出。JavaScriptレンダリングとクエリに焦点を当てたチャンク分割をサポート。JavaScriptでレンダリングされたページを処理し、抽出深度を設定可能（シンプルなページは基本、動的なSPAやテーブルは高度）。クエリに焦点を当てた抽出をサポートし、全ページではなく関連コンテンツのチャンクのみを返却。デフォルトでLLM最適化されたマークダウンを返し、プレーンテキスト形式や構造化JSON出力のオプションも提供。1回の呼び出しで最大20件のURLを処理。

tavily extract

Extract clean markdown or text content from one or more URLs.

Before running

Run extract directly when tvly is available. Extract supports capped keyless access, so do not look for an API key or authenticate before the first request.

If tvly is missing, follow the tavily-cli setup before retrying. If the keyless cap is reached in an interactive session, run tvly login to open browser OAuth, then retry the original extraction once. In an unattended environment, report the cap and authentication options instead of starting an interactive flow. Do not start a second login immediately after guided setup has completed.

When to use

You have a specific URL and want its content
You need text from JavaScript-rendered pages
Step 2 in the workflow: search → extract → map → crawl → research

Quick start

# Single URL
tvly extract "https://example.com/article" --json

# Multiple URLs
tvly extract "https://example.com/page1" "https://example.com/page2" --json

# Query-focused extraction (returns relevant chunks only)
tvly extract "https://example.com/docs" --query "authentication API" --chunks-per-source 3 --json

# JS-heavy pages
tvly extract "https://app.example.com" --extract-depth advanced --json

# Save to file
tvly extract "https://example.com/article" -o article.json

Options

Option	Description
`--query`	Rerank chunks by relevance to this query
`--chunks-per-source`	Chunks per URL (1-5, requires `--query`)
`--extract-depth`	`basic` (default) or `advanced` (for JS pages)
`--format`	`markdown` (default) or `text`
`--include-images`	Include image URLs
`--timeout`	Max wait time (1-60 seconds)
`-o, --output`	Save the JSON response to a file
`--json`	Structured JSON output

Extract depth

Depth	When to use
`basic`	Simple pages, fast — try this first
`advanced`	JS-rendered SPAs, dynamic content, tables

Tips

Max 20 URLs per request — batch larger lists into multiple calls.
Use --query + --chunks-per-source to get only relevant content instead of full pages.
Try basic first, fall back to advanced if content is missing.
Set --timeout for slow pages (up to 60s).
Inspect failed_results even after exit code 0. A successful request can still return no extracted pages. Retry the affected URL with advanced when appropriate, otherwise report the per-URL failure instead of treating the request as complete.
If search results already contain the content you need (via --include-raw-content), skip the extract step.
