Give your agents the whole web, as data.

Crawl, scrape and search the web with one API. Get clean markdown or JSON back for your agents.

# The Rust Programming Language

*by Steve Klabnik, Carol Nichols, and Chris Krycho, with contributions from the Rust Community* This version of the text assumes you’re using Rust 1.90.0 (released 2025-09-18) or later with `edition = "2024"` in the *Cargo.toml* file of all projects to configure them to use Rust 2024 Edition idioms.

Three products. One key.

Start with the API. The browser and the proxy network also work on their own. The trace below is one crawl through all three.

example trace
  • api.spider.cloud

    Step one of an example trace, captured 2026-09-05. The API receives POST /crawl for doc.rust-lang.org/book with a limit of 30, hands the job to the browser, waits, and returns 30 pages of markdown totalling 331 kilobytes with status 200. Every page came back 200. demo-01 is an illustrative correlation id, not an API field.

  • browser.spider.cloud

    Step two. The browser opens a session, accepts the request from the API, routes it through an ISP exit in Germany, loads each of the 30 pages from doc.rust-lang.org/book, and hands the markdown back to the API before closing the session. demo-01 is an illustrative correlation id, not an API field.

  • proxy.spider.cloud

    Step three. The network accepts the browser's request and routes it through an ISP exit in Germany, rotating the exit per request, then fetches the 30 pages from doc.rust-lang.org/book and returns them to the browser. The pool is 215M+ exits in 199 countries. demo-01 is an illustrative correlation id, not an API field.

Crawl, scrape, search

Whole sites or single pages, returned as markdown, JSON, links or screenshots. Search the web from the same key.

See the API

A browser we wrote

Headless, written from scratch in Rust. Stealth and CAPTCHA solving are on by default, up to 100 sessions at once.

See the browser

The network underneath

215M+ residential and ISP exits in 199 countries, rotated per request. Works with our browser or yours.

See proxy locations

Use the whole web like a dataset.

Most websites have no API. Spider renders their pages and extracts the content for your RAG pipeline or agent.

Proxy locations

  1. Renders like a user

    JavaScript, infinite scroll, lazy media. The page as a person sees it.

    request: "browser"

  2. Handles anti-bot checks

    CAPTCHAs and geo walls, handled by the browser and the network together.

    stealth: true

  3. Extracts the content

    Clean markdown or structured JSON from the rendered page.

    return_format: "markdown"

  4. Streams in order

    Whole sites arrive page by page while the crawl runs. Nothing waits for the last URL.

quickstart

01Get a key

Create API key

Sign up and copy the key. New accounts start with a free balance.

export SPIDER_API_KEY="sk-..."

SDKs, the MCP server and every command read it.

02 Connect Claude Code Client configs in the docs 

claude mcp add spider --transport http \
  https://mcp.spider.cloud/mcp \
  -H "Authorization: Bearer $SPIDER_API_KEY"
Read and follow https://spider.cloud/agent-skill/SKILL.md

Or skip MCP and let the agent onboard itself

03Read the data

example output example data after a scrape
[{
  "url": "https://example.com",
  "status": 200,
  "content": "# Example Domain\n\n..."
}]

The connection comes first. Data like this arrives once the client makes a request.

Markdown or JSON, streamed. Drop it into your RAG store, agent context or database.

Start with one URL.
