Questions

FAQ

How do I use the Reddit App Post Comments API?

Send a POST request to https://api.sandbase.ai/v1/api/reddit/app/post-comments 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 Post Comments 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 Post Comments API accept?

Required: post_id (string). Optional: after (string), need_format (boolean) and sort_type (string). The Parameters table and the Playground on this page list every field.

What does the Reddit App Post Comments API return?

A JSON response returned in the same HTTP request (synchronous).

Do I need a Reddit developer account or API key?

No. Reddit App Post Comments runs through SandBase, so one SandBase API key covers this endpoint and every other API and model in the catalog. You do not need to apply for Reddit API access separately.
