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-sourceto get only relevant content instead of full pages. - Try
basicfirst, fall back toadvancedif content is missing. - Set
--timeoutfor slow pages (up to 60s). - Inspect
failed_resultseven after exit code 0. A successful request can still return no extracted pages. Retry the affected URL withadvancedwhen 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.
