Was er kann

Tool-Namen und -Beschreibungen genau so, wie der Server sie am 6. Nov. 2026 gemeldet hat. Geschrieben hat sie der Entwickler, nicht wir; wir zeigen sie als reinen Text.

• alterlab_scrape

  Fetch one URL and return its content as clean markdown, text, HTML, or JSON. Use when a normal fetch returns 403/429, a bot-protection challenge page, a CAPTCHA, or an empty JavaScript shell. Website challenges and JavaScript-heavy pages are handled automatically by a 5-tier syst

• alterlab_extract

  Extract structured data (prices, product info, contact details, custom fields) as JSON from HTML, text or markdown you already hold. Use when you have content and need specific fields. Does not fetch a URL: to fetch and extract in one step, use alterlab_scrape with extraction_sch

• alterlab_screenshot

  Capture a full-page PNG screenshot of one URL, an image rather than text content. Use when a normal fetch returns 403/429, a bot-protection challenge page, a CAPTCHA, or an empty JavaScript shell. Works on anti-bot-protected sites, rendered in a real headless browser. Use wait_fo

• alterlab_crawl

  Crawl a whole website and return the content of every page, for RAG, indexing or site-wide export. Use when you need many pages from one domain; for one URL use alterlab_scrape, for a URL list only use alterlab_map. Works on JavaScript-heavy and protected sites, with anti-bot han

• alterlab_search

  Search the web and get structured results (URLs, titles, snippets). Use when you have a question or topic but no URL yet; follow up with alterlab_scrape to read a page, or set scrape_results=true to read every result in one call. Use domain to restrict to one site and time_range

• alterlab_map

  List every URL on a site via sitemap parsing and link extraction, without fetching page content. Use before alterlab_crawl or alterlab_batch to choose pages; to read the content itself use alterlab_crawl. Works on JavaScript-heavy and protected sites. When you present results to

• alterlab_batch_scrape

  Scrape 2-20 URLs in parallel and get every result back in one synchronous call, no polling required. Use when a normal fetch returns 403/429, a bot-protection challenge page, a CAPTCHA, or an empty JavaScript shell. Failed URLs report their error; successful ones return content.

• alterlab_batch

  Start an asynchronous batch job for a large URL set (up to 100 per call) and poll for results later. Use when a normal fetch returns 403/429, a bot-protection challenge page, a CAPTCHA, or an empty JavaScript shell. Each URL can have its own mode, formats and extraction_schema. R

• alterlab_estimate_cost

  Estimate the credit cost of scraping a URL before you run it. Use when cost matters or before a large job; no credits are charged. Returns the predicted tier, estimated cost and confidence. Full machine-readable price list: GET https://alterlab.io/api/v1/pricing (public, no auth)

• alterlab_pricing

  Get AlterLab's machine-readable price list: per-tier cost, bring-your-own-proxy discount, cache-hit discount, add-ons, search and SERP prices, and the free allowance. Use when deciding whether AlterLab fits a budget, before any account exists. Free and keyless; nothing is scraped

• alterlab_news

  Search aggregated news headlines from curated public sources: headline, URL, source, published time, author, image, short snippet and category. Use to find what is being reported on a topic. Served from a cache that refreshes about every 15 minutes, so a call never triggers a fet

• alterlab_keyword_ideas

  Fan out a seed keyword across autocomplete (seed + a-z + who/what/how/why/best/vs), People Also Ask and related searches, and get deduplicated ideas, each with source, question flag, intent (question, commercial, navigational, informational) and a 0-1 relevance score. volume is a

• alterlab_ai_visibility

  Run prompts against AI answer engines through their public, logged-out interfaces and get, per engine and run, the answer text, whether the brand is mentioned and its position, competitors mentioned, cited URLs and domains and a sentiment label, plus per-prompt mention rate, shar

• alterlab_feedback

  Tell AlterLab when something is hard, or what would make it better. Call this when something blocks you, a result is wrong, or a step is confusing, slow or priced unexpectedly, and also to send a suggestion (category `suggestion`, ideas welcome even when nothing is broken). Descr

• alterlab_support_ticket

  Open a support ticket in your user's AlterLab account when they need a human: a billing, account or data problem. Do not use it for scrape friction, blocks or ideas; use `alterlab_feedback` for those. Ask the user first: a ticket reaches a human and emails them. Requires an API k

• alterlab_create_account

  Create an AlterLab account and API key for your user. Use only when no ALTERLAB_API_KEY exists yet; skip it if a key is already configured. Signup is on behalf of your user (agent signup with human approval). Nothing is created until the human approves: they get an email (and you

• alterlab_create_api_key

  Create one scoped, spend-capped API key (ALTERLAB_API_KEY) for the SDK and REST API on this machine. Works only when the user ticked "Also create an API key for this machine" on the OAuth approval screen, so no second approval is needed. Skip it if a key is already configured. Th

• search_alterlab

  Use this to look up how to do something with AlterLab (API parameters, SDKs, MCP setup, pricing, error codes, migration from Firecrawl/ScrapingBee/Apify) or to find a guide for scraping a specific site. Searches the docs guides and API reference by default (blog posts only when y

• read_alterlab_page

  Use this after search_alterlab to read the full text of one AlterLab page as markdown, so you can follow the documented steps instead of guessing. Pass the url of a search result. Only pages on alterlab.io that search_alterlab can return are readable. Free: needs no API key and n

• alterlab_serp

  Query a search engine and get structured results: organic listings, ads and related data, from Google, Bing or DuckDuckGo. Use action=search (default) to run a query, or action=history to read earlier SERP queries for your account. Prefer alterlab_search when you also want each r

• alterlab_job

  Look up a job by id. action=status (default) returns its status and result once finished; set wait (seconds) to hold the request until the job reaches a terminal status. action=explain returns the ordered per-stage timing breakdown, useful when a job was slow or failed. Job ids c

• alterlab_balance

  Read account credit data. action=balance (default) returns the current credit balance in microcents (1,000,000 microcents = $1.00) with formatted values. action=usage returns usage statistics. Read-only; call it before an expensive crawl or batch to confirm there are enough credi

• alterlab_monitor

  Manage change monitors. action=create watches a URL on a cron schedule and notifies by webhook when content changes; action=list returns your monitors; action=delete removes one by monitor_id (it stops running and cannot be restored). Each check spends credits like a scrape.

• alterlab_schedule

  Manage recurring scrape schedules. action=create runs a scrape of one or more URLs on a cron expression; action=list returns your schedules; action=delete removes one by schedule_id (it stops triggering). Every run spends credits like a scrape; minimum intervals depend on your ba

• alterlab_workflow_run

  Start an execution of a workflow you saved in the AlterLab dashboard. Optional input_data is passed to the workflow's webhook trigger node. Returns run_id, workflow_id and the initial status. The run spends credits for the steps it executes.
