How much does the Facebook Post Comment Replies API cost?

10 credits per successful call.

  • Failed calls are free

    A call that errors or finds nothing costs 0 credits.

  • Know the price first

    Add dry_run=1 and the response quotes the call without making it. Nothing is charged.

  • One balance

    API calls and Chrome extension exports share the same credits, on the free plan too.
