TinyFish is a CLI for web scraping and automation that escalates gracefully from simple fetches to full browser control. Start with search to find URLs, use fetch for clean content extraction from static pages, jump to agent when you need natural language instructions to click buttons or fill forms, and only reach for the CDP browser session when you need raw programmatic control. The agent command is the standout here: you pass a URL and a plain English goal like "extract all products as JSON" and it handles the interaction. Works well for bot-protected sites. The tool selection ladder (search → fetch → agent → browser) is smart, keeps costs down, and the parallel execution model means you fire off separate commands for independent sites rather than cramming everything into one brittle goal.

You have access to the TinyFish CLI (tinyfish) — a suite of web tools you can call from the terminal.
If not installed: npm install -g @tiny-fish/cli
If not authenticated: tinyfish auth login --source openclaw or set TINYFISH_API_KEY env var.
Use TinyFish whenever a request depends on live web information or page content. Do not wait for the user to say "TinyFish" or "scrape".
Strong triggers include:
Default to the lightest tool that can answer:
search, then fetch the best result(s) if more detail is needed.fetch.agent.browser.TinyFish has four tools. Start with the lightest one that can do the job and escalate only when needed.
search → fetch → agent → browser
lightest heaviest
| Tool | When to use | Speed | Cost |
|---|---|---|---|
| search | You need to find URLs, current facts, docs, pricing, product details, or a quick source-backed answer | Fastest | Lowest |
| fetch | You have URLs and need clean page content, summaries, article text, docs, product pages, links, or metadata | Fast | Low |
| agent | You need to interact with a page — click, fill forms, navigate, extract structured data from dynamic sites | Slower | Higher |
| browser | Agent isn't enough — you need raw programmatic browser control via CDP | Slowest | Highest |
Research: search → fetch Search for a topic, then fetch the best results to read their full content.
# 1. Find URLs
tinyfish search query "best React state management libraries 2026"
# 2. Read the top results
tinyfish fetch content get --format markdown "https://result1.com" "https://result2.com"
Deep extraction: search → agent Search to find the right site, then use agent to interact with it and extract structured data.
# 1. Find the site
tinyfish search query "Nike running shoes official store"
# 2. Automate extraction on it
tinyfish agent run --url "https://nike.com/running" \
"Extract all running shoes as JSON: [{\"name\": str, \"price\": str, \"colors\": [str]}]"
Escalation: fetch → agent Try fetch first. If the page is dynamic/JS-heavy and fetch returns empty or incomplete content, escalate to agent.
Full control: agent → browser If agent can't handle a complex multi-step workflow, spin up a raw browser session and automate it yourself via CDP.
tinyfish search queryWeb search. Returns ranked results with titles, URLs, and snippets.
tinyfish search query "<query>" [--location <hint>] [--language <hint>] [--pretty]
--location and --language for geo-targeted results--pretty for human-readabletinyfish search query "best pho in Ho Chi Minh City" --location "Vietnam" --language "en"
tinyfish fetch content getFetch clean, extracted content from one or more URLs. Strips ads, nav, boilerplate — returns just the content.
tinyfish fetch content get <urls...> [--format markdown|html|json] [--links] [--image-links] [--pretty]
--format markdown (default) — clean readable text--format json — structured document tree--links — include all extracted links from the page--image-links — include extracted image URLsurl, final_url, title, language, author, published_date, text, latency_ms# Fetch one page as markdown
tinyfish fetch content get --format markdown "https://example.com/article"
# Fetch multiple pages with links
tinyfish fetch content get --links "https://site-a.com" "https://site-b.com" "https://site-c.com"
tinyfish agent runRun a browser automation using a natural language goal. The agent opens a real browser, navigates, clicks, fills forms, and extracts data.
tinyfish agent run --url <url> "<goal>" [--sync] [--async] [--pretty]
| Flag | Purpose |
|---|---|
--url <url> | Target URL (bare hostnames get https:// auto-prepended) |
--sync | Wait for full result without streaming steps |
--async | Submit and return immediately |
--pretty | Human-readable output |
Output: Default streams data: {...} SSE lines. The final result is the event where type == "COMPLETE" and status == "COMPLETED" — the extracted data is in the resultJson field. Read the raw output directly; no script-side parsing is needed.
Always specify the JSON structure you want in the goal:
tinyfish agent run --url "https://example.com/products" \
"Extract all products as JSON array: [{\"name\": str, \"price\": str, \"url\": str}]"
tinyfish agent run --url "https://example.com/search" \
"Search for 'wireless headphones', filter under $50, extract top 5 as JSON: [{\"name\": str, \"price\": str, \"rating\": str}]"
Parallel extraction — when hitting multiple independent sites, make separate calls. Do NOT combine into one goal.
Good — parallel calls (run simultaneously):
tinyfish agent run --url "https://pizzahut.com" \
"Extract pizza prices as JSON: [{\"name\": str, \"price\": str}]"
tinyfish agent run --url "https://dominos.com" \
"Extract pizza prices as JSON: [{\"name\": str, \"price\": str}]"
Bad — single combined call:
# Don't do this — less reliable and slower
tinyfish agent run --url "https://pizzahut.com" \
"Extract prices from Pizza Hut and also go to Dominos..."
Managing runs:
tinyfish agent run list [--status PENDING|RUNNING|COMPLETED|FAILED|CANCELLED] [--limit N]
tinyfish agent run get <run_id>
tinyfish agent run cancel <run_id>
Batch operations — submit many runs from a CSV file (url,goal columns):
tinyfish agent batch run --input runs.csv
tinyfish agent batch list
tinyfish agent batch get <batch_id>
tinyfish agent batch cancel <batch_id>
tinyfish browser session createSpin up a remote browser instance. Returns a CDP WebSocket URL for programmatic control.
tinyfish browser session create [--url <url>] [--proxy-country <code> | --proxy-url <url> [--proxy-username <user>] | --no-proxy] [--pretty]
--url optionally navigates to a page after creationsession_id, cdp_url (WebSocket), and base_urlcdp_url with Playwright, Puppeteer, or any CDP client--proxy-country <code> picks another exit country (ISO 3166-1 alpha-2, e.g. DE, JP)--proxy-url <url> routes through the user's own HTTP(S) proxy; --proxy-username <user> for auth, password via TINYFISH_PROXY_PASSWORD env (never a flag)--no-proxy connects directly, without a proxytinyfish browser session create --url "https://example.com"
# Returns: { session_id, cdp_url: "wss://...", base_url: "https://..." }
tinyfish browser session create --url "https://example.de" --proxy-country DE
--pretty for human-readable output. Default is JSON.--debug on the root command or set TINYFISH_DEBUG=1 to log HTTP requests to stderr.Sponsors
