UNOFFICIAL ENDPOINT DISCLAIMER
This server communicates with the same internal endpoints that the trends.google.com frontend uses. These endpoints are undocumented and unofficial. Google can change, rate-limit, or remove them at any time without notice. This project is not affiliated with, endorsed by, or sponsored by Google LLC. "Google Trends" is a trademark of Google LLC.
If requests start failing, open an issue. The fix is usually a URL or parameter tweak.

npm test
# Build TypeScript to dist/
npm run build
# Run the server locally (stdio mode)
node dist/index.js
Rate limits and blocking
Google does not publish a rate limit for these endpoints. In practice, a few requests per minute works reliably. If you hit HTTP 429 or get blocked, the server returns a descriptive error message. Waiting 2-5 minutes usually resolves it.
