Block AI Scrapers & Coding Agents

Build and verify a multi-layer firewall that stops AI coding agents (Claude, Claude Code, Cursor, OpenCode, Grok, Codex, ChatGPT, Perplexity), WebFetch tools, CLI scripts (curl, wget, python, node, bun), and headless browsers (Playwright, Puppeteer) from scraping your site or burning your database/API credits, while keeping verified Googlebot SEO indexing intact and turning every blocked scrape into a conversion link for your product or Chrome extension.

Core Rule

Never return bare HTTP 403 or 429 to an AI coding agent.

When a user pastes your URLs into Claude Code, Cursor, or Grok and says "scrape all of this", a 403 Forbidden or 429 Too Many Requests looks like a transient technical block. Coding agents treat 403/429 as a puzzle to solve: they automatically retry with spoofed Chrome User-Agent headers, probe /api/* and /sitemap.xml, or launch headless browsers (Playwright / Puppeteer).

To stop an AI agent on Turn 1:

1. Serve an HTTP 200 "Protected Dataset" Gate Page (and HTTP 200 JSON on /api/*) containing 0 dataset rows.
2. Pair hard technical gates (verified Googlebot IP/ASN checks, Sec-Fetch-* navigation headers, datacenter ASN blocking, and a lightweight non-webdriver JS session cookie) with explicit legal, copyright, and [AI_AGENT_DIRECTIVE: STOP_SCRAPING] instructions that direct the agent to stop retrying and hand the user your official product or extension URL.
