Frequently asked questions
Everything about the Scanr.ai scanner and plans — plus our programmatic API and MCP server access.
Scanner & plans
What markets are supported?
Scanr currently supports all US markets and exchanges, including all stocks registered on the NYSE, NASDAQ, AMEX, CBOE, and more. Our Super Pro plan also supports OTCs and ETFs.
Does the scanner update results in real-time?
Yes, on Super and Super Pro plans, the scanner refreshes results in near real-time. Our free Starter plan runs on market data delayed by 15 minutes.
Do my saved scans keep running in the background?
On Super and Super Pro, yes — we re-run your saved scans for you and alert you the moment one finds new tickers, whether or not you have Scanr open. On the free Starter plan your saved scans only run when you run them.
Does the scanner support nested groups and complex conditions?
Yes, the scanner supports nested groups and complex conditions. All indicators can be compared against other arbitrary indicators, for example, 'RSI > 50 and SMA(50) > SMA(200)'.
What timeframes are supported?
We support all major timeframes from 1 minute to 1 month. The free Starter plan only supports 1 day scanning.
What can the scanner screen on?
Technical indicators, fundamental metrics, candlestick and chart patterns, insider activity, short interest, supply/demand zones and relative strength. Any indicator can be compared against any other and wrapped in modifier chains (slope, correlation, crossovers, divergences), so the set of expressible conditions is open-ended rather than a fixed list. Fundamental filters are available on the Super and Super Pro plans.
Do you offer a programmatic API?
Yes — our REST API and MCP server are live. See our API pricing for tiers and rate limits, or browse the full API reference.
Is there a mobile app?
Yes. Scanr.ai has a mobile app so you can scan and track the market on the go. Learn more on our mobile app page.
API access & MCP
Is API pricing separate from my Scanr UI plan?
Yes. API access is a standalone add-on. You can be on the free Starter UI plan and still subscribe to any API tier, or be on Super Pro and stay on the free Starter API tier. The two products are billed independently and have their own rate limits.
Do API limits stack with my UI plan's limits?
No. API requests made with an API token (and through the MCP server) are metered against your API tier's limits — not your UI plan's per-session limits. They are completely separate buckets.
What's included in the MCP server access?
Every API tier includes access to our MCP server with the same tools — scanning, natural-language scan, security search, market status, news, and trending stocks. AI tools on MCP are metered against your daily API-tier AI quota, shared with the REST AI scan endpoints. See the MCP docs for setup.
Can I upgrade, downgrade, or cancel anytime?
Yes. You can change your API tier or cancel at any time from your account billing portal. Upgrades take effect immediately with a prorated charge; downgrades and cancellations take effect at the end of your current billing period.
What happens if I hit a rate limit?
API responses include standard rate-limit headers so you can back off gracefully. If you exceed the limit, you'll receive a 429 response. AI-specific endpoints have their own daily quota (separate from the general request limits) because LLM calls are more expensive to serve.
Do you offer custom or enterprise pricing?
Yes — if the Business tier's limits aren't enough or you need custom terms, get in touch at [email protected].
Where can I find the API documentation?
Full reference docs are available at api-docs.scanr.ai. You can mint API tokens from your account settings.
