AltF API & Widgets is a read-only console for AltFTool's public HTTP endpoints: you send a GET request to /api/signals, /api/signals?sort=volume or /api/health, read the raw JSON response on the page, and copy a matching cURL or fetch snippet. There are no write endpoints, no API keys and no authentication - these are public read routes, and they are rate limited per client.

All of them are unauthenticated GET requests.
