X API v2 has a Post consumption cap that limits the number of Posts that can be retrieved from specific endpoints on a monthly basis. Post caps apply at the Project level, meaning that any requests to the endpoints listed below using the keys and tokens from developer Apps within that Project will count towards the Project Post cap.

​
Limited v2 endpoints

Posts received from any of the following endpoints count towards this monthly Post cap:
Note: If the same Post is returned from multiple queries during a day, it only counts once against the Post cap; Posts are deduplicated daily.

​
Post cap volumes

The Post cap volume varies based on your access level:
Access TierMonthly Post Cap
Free100 Posts per month
Basic15,000 Posts per month
Pro1,000,000 Posts per month
Enterprise50+ million Posts per month
You can check your usage towards the monthly Post cap by viewing the main dashboard page in the developer portal. Under the name of your Project, you’ll see a status bar that shows your current month’s usage in relation to the Post cap, including the total Posts pulled, the percentage of Posts used, and the reset date for your usage.
