To fetch a web page as Markdown programmatically, call the Supadata API. One GET request, no SDK needed:
Using Claude, ChatGPT or Cursor? Add Supadata in one click and sign in, no key to paste (other AI agents):
Machine-readable site map: llms.txt. Endpoint reference: docs.supadata.ai/web/scrape.
Supadata’s web scraping API has three endpoints: scrape for one page, map for every URL on a site, and crawl for the content of a whole site. All of them return clean Markdown or plain URL lists, never raw HTML.
Web scrapers stop at the text. A product page with a demo video, a docs site with YouTube tutorials or a creator’s landing page with TikToks holds most of its information in the videos, and an HTML scraper can’t read them.
With Supadata, the same API key that scrapes the page also gets the videos:
One account, one bill, one SDK for both the web and video sides of your AI pipeline. Get your free API key →
Nobody likes bloated APIs and unnecessary complexity. That’s why we’ve built our service to be:
Feed LLMs clean, current content:

The best web scraping API depends on what you scrape. Here is how Supadata compares with popular options for LLM-ready output (as of October 2026):
”—” means not offered as a built-in endpoint on the vendor’s site.
Honest take: if you scrape only web pages at very high volume, Firecrawl is cheaper per page on its larger plans. If you fight heavy anti-bot protection, ScrapingBee is built around proxies. For converting the odd single URL with no sign-up, Jina Reader is fine. Choose Supadata when your app needs both web pages and video content, with one key and one bill. See the full Firecrawl alternative comparison.
Try it free → — 100 requests/month, no credit card.
1 page = 1 credit, whether you scrape it on its own or as part of a crawl. A site map is 1 credit. Start free with 100 requests a month; paid plans scale to 1,000,000 credits.
Scrape a page or map a site in one call. No browser to run, no proxies to manage, no HTML to clean up.
Crawl a whole site. Crawling runs as a job: start it, then poll until status is completed. Polling is free.
What does the Web Scraping API return?
Clean Markdown of the page plus its title, description, Open Graph image, character count and the list of links found on the page. Pass noLinks=true to strip Markdown links and keep only the link text.
Does it work on JavaScript-heavy websites?
Yes. Pages are rendered before extraction, so content that single-page apps load with JavaScript ends up in the Markdown.
How does crawling work and what does it cost?
POST /v1/web/crawl with a URL and an optional page limit (default 100, max 5,000) returns a job ID. Polling the job is free and every crawled page costs 1 credit. The crawler follows links below the starting URL. Crawl is available on the Pro plan and above.
How do I get every URL on a website?
Call GET /v1/web/map with the site URL. It returns the URLs found on the site for 1 credit, so you can pick which pages to scrape.
Can it get the content of videos embedded on a page?
Yes, with the same API key. Send a YouTube, TikTok, Instagram, X or Facebook video URL to /v1/transcript for its transcript, or to /v1/extract for structured data from a prompt.
Can AI agents use it?
Yes. Add Supadata to Claude, ChatGPT or Cursor in one click and your agent gets scrape, map and crawl tools (via the Supadata MCP server, which also works in other MCP clients). The same endpoints are available in Make, Zapier, n8n and Active Pieces.
Is web scraping legal?
Scraping publicly available pages is generally allowed, but it depends on your jurisdiction, the site’s terms and how you use the data. Respect robots.txt and each site’s terms of service, and don’t collect personal data without a legal basis.
A web scraping API fetches a web page for you and returns its content in a format your code can use. For AI applications, that format is increasingly Markdown rather than HTML. This guide covers how scraping APIs work, why Markdown matters for LLMs, and when to scrape, map or crawl.
A web scraping API is a hosted service that loads a URL, renders it like a browser, and returns the useful content through a simple HTTP request. It replaces the stack you would otherwise run yourself: headless browsers, retry logic, HTML parsers and the cleanup code that strips navigation, ads and cookie banners. You send a URL and an API key; you get structured content back.
Markdown keeps the structure an LLM needs (headings, lists, tables, links) and drops everything it doesn’t (scripts, styles, layout divs and tracking markup). A typical page is several times smaller as Markdown than as raw HTML, so it costs fewer tokens, fits more context into a prompt and splits cleanly into chunks for retrieval-augmented generation (RAG). That’s why AI-focused scrapers like Supadata, Firecrawl and Jina Reader all return Markdown by default.
