Credit limits, counting rules, and response headers

Limits by Tier

Tier	Included Monthly Credits
Starter	1,000 credits
Plus (Individual)	100,000 credits
Pro (Individual)	1,000,000 credits
Business	1,000,000 credits per seat

Counting Rules

Most API calls cost 1 credit, including Search.
OHLCV costs 1 credit per 100 bars returned, rounded up, with a 1 credit minimum for valid requests.
Watchlist GET costs 1 credit per ticker, and summary event lookups with cross-asset correlation cost 2 credits.
/v1/summary/:ticker returning 404 (unknown ticker) does not count against limits
HTTP 304 (conditional/cached) responses do not count
Monthly usage resets at 00:00 UTC on the first day of each calendar month
Plus, Pro, and Business continue after the included monthly amount and additional usage is billed at $1 per 10,000 requests
Starter has no overage billing and returns HTTP 429 when its monthly quota is exhausted
Business limits are per seat. Team members do not share rate limits, watchlist capacity, or webhook URL capacity.

Monthly Usage
