Massive (web rendering)

Use Massive to fetch hard-to-retrieve web pages. Massive is available as a built-in tool for Agents and as a fetch method on the Fetch URL step in a Flow, alongside Firecrawl.

What is Massive?

Massive Web Render fetches a page by rendering its JavaScript, solving CAPTCHAs, and retrying through a residential network. Use it for pages that block or challenge data center traffic. Massive returns LLM-optimized Markdown, rendered HTML, or raw HTML, and it supports country-based geotargeting.

Use Massive for the following cases:

  • Hard-to-reach pages: Fetch sites that block, rate-limit, or challenge data center traffic.
  • Localized content: Fetch pages as seen from a specific country.
  • Dynamic pages: Capture content that appears only after JavaScript runs.

Set up Massive

Massive Web Render is available only when it is enabled for your account. When it is enabled, you can use it with a Runtype platform key without adding your own API key. If you use your own Massive account, follow these steps:

  1. Sign up at Massive.
  2. Copy your API key from the Massive dashboard.
  3. In Runtype, click Settings > Integrations.
  4. In the Web Scraping section, find Massive.
  5. In the Massive API Key field, paste your API key.
  6. Click Save Key.

Use Massive as a tool

Enable the Massive Web Render built-in tool when you configure an Agent. The Agent uses the tool to fetch pages that resist ordinary HTTP requests.

The Agent calls the tool with the following parameters:

  • url (required): The full URL of the page.
  • format: The output format, either markdown (default), rendered (HTML after JavaScript runs), or raw (HTML before JavaScript runs).
  • country: A two-letter ISO country code, such as us. If omitted, Massive picks a random country.
  • delay: Extra wait time, from 0.1 to 10 seconds, before Massive captures the content of a slow-loading page.

Use Massive in a Flow

On the Fetch URL step, set the fetch method to Massive (Web Render). The step routes the request through Massive instead of a raw HTTP fetch. You can configure the output format, geotargeting, delay, and cache expiration.

Choose between Massive and Firecrawl

Both services fetch pages that block ordinary requests. Firecrawl adds structured extraction options, including JSON extraction, page actions, and main-content stripping. Massive focuses on difficult sites with residential geotargeting and CAPTCHA solving. If one service cannot retrieve a page, try the other.
