What counts as a credit?
expand_more
Each feature in a request costs 1 credit (2 to 5 for advanced Pro features), regardless of how many rows are returned. A request with 3 features and 200,000 bars costs 3 credits. Paginated requests only charge on the first page, subsequent pages are free. Credits reset every day at midnight UTC and do not carry over.
Can I use the Demo plan in production?
expand_more
Yes. The Demo plan has no time limit and is free forever. The constraints are 100 credits/day, 30 requests/min, 307 features (no MEDIUM or HEAVY tier features), and 2 years of history (both daily and intraday). If those limits work for your use case, you can run Demo in production indefinitely.
What happens if I hit my daily credit limit?
expand_more
Requests return HTTP 429 (Too Many Requests) until midnight UTC, when the counter resets. The response includes an X-Credits-Day-Used header so you can track usage. You can upgrade your plan at any time to increase your daily allowance, upgrades take effect immediately.
Is intraday data available on Demo?
expand_more
Yes. Demo includes intraday timeframes (1h, 4h) with up to 2 years of history through the data API. Backtester on Demo is restricted to 1h, 4h and 1d timeframes; 1m / 5m / 15m backtesting opens up on Basic. For higher rate limits and longer intraday history (3 years on Basic, 5 years on Pro), upgrade.

expand_more

Is there a rate limit beyond credits?
expand_more
Yes, a per-minute rate limit prevents burst abuse. Demo: 30 credits/minute, Basic: 120/minute, Pro: 600/minute. In practice you will rarely hit the per-minute limit unless you are sending many parallel requests. The daily credit limit is the main constraint.
