FAQ
How do I use the Reddit App Comment Replies API?
Send a POST request to https://api.sandbase.ai/v1/api/reddit/app/comment-replies with your SandBase API key in the Authorization header (Bearer) and the parameters as a JSON body. You can also try it in the Playground on this page without writing code.
How much does the Reddit App Comment Replies API cost?
$0.0015 per call. Every organization gets 100 free calls per UTC day, shared across eligible SandBase APIs including this one; after that each call is billed at this price from your SandBase balance. There is no subscription.
What parameters does the Reddit App Comment Replies API accept?
Required: cursor (string) and post_id (string). Optional: need_format (boolean) and sort_type (string). The Parameters table and the Playground on this page list every field.
What does the Reddit App Comment Replies API return?
