How to track your API and AI Chat usage

Q: Where can I see how many AI Chat questions I have left?

Open Settings and check the chat usage section for your remaining AI Chat quota.

Q: What happens if I hit my rate limit?

Requests over the per-minute limit are throttled. Add backoff and retry logic, cache stable data, or upgrade to a higher tier for more headroom.

Q: Where do I monitor API usage?

Open Settings to see your rate limit and recent request counts alongside your API key.

Q: Which limits does my plan include?

Plans cap API calls per minute, AI Chat questions, alert notifications per day, and file storage. Current values are on the pricing page.

Q: What should I do if I keep hitting a limit?

Cache and batch API calls where possible, or upgrade - Ultimate offers the highest limits across the board.

Each Vantafin plan includes limits on API requests per minute, AI Chat questions, alert notifications, and file storage. You can monitor all of it from Settings so you never get surprised by a limit. This guide shows where to look and how to stay within your plan.

Where to find usage

Open Settings to see:

API usage - your rate limit and recent request counts, alongside your API key.
Chat usage - your AI Chat question quota and how much you have used.

Current limit values for each plan are on the pricing page.

Understand the limits

Limit	Applies to	Notes
API calls/minute	REST + WebSocket	Highest on Ultimate
AI Chat questions	AI Chat	Highest on Ultimate
Alert notifications/day	Alerts	Highest on Ultimate
File storage	Research drive	Highest on Ultimate

Stay within your plan

A few habits keep you comfortably under the limits:

Cache API responses that rarely change (like historical fundamentals). See Query data with the REST API.
Batch requests where an endpoint supports multiple symbols.
Scope alerts to watchlists instead of creating many single-ticker alerts.
Prune old files from your drive to free storage.

When you need more headroom

If you routinely hit a limit, upgrading is the simplest fix - Ultimate offers the highest limits across the board. Compare tiers in choosing a plan, then upgrade.
