Spider

What is Spider?

Spider is a web data API for developers who need to crawl, scrape, search and screenshot pages at scale. A single bearer-token API covers crawling whole sites, fetching single pages as HTML, markdown, text or JSON, searching the web, and extracting structured fields with AI or CSS selectors. Pages that need JavaScript are loaded in a native browser with rotating proxies and retries, and a cloud browser endpoint is compatible with Playwright and Puppeteer over a CDP WebSocket. Results can be streamed as they finish or sent to S3, Google Cloud, Azure Blob, Sheets or Supabase. Spider pricing is pay as you go: $1 per GB of bandwidth plus $0.0001 per minute of compute, failed requests cost nothing, and credits do not expire. There is also a monthly Unlimited concurrency plan from $40/month and AI Studio add-on plans from $6/month for prompt-driven endpoints.

Use cases

• Crawl sites into markdown for RAG
• Scrape JavaScript-heavy pages
• Search the web and scrape results
• Capture full-page screenshots
• Extract structured data with AI
• Route requests through residential proxies
• Run cloud browser sessions

Who it's for

• Developers
• AI engineers
• Data teams

Why use Spider

• Billing is two simple line items, bandwidth and compute, with no multiplier for JS rendering and nothing charged for failed requests.
• Credits do not expire, so you can top up once and use the balance whenever it suits you.
• One API covers crawling, scraping, search, screenshots and a browser, so you avoid stitching together separate vendors.
• You can choose per-request billing or buy concurrency for a flat monthly rate when volume is steady.
• Streaming and connectors let pages flow into storage or your own code as they finish.
