Priced per comment by platform: Reddit $0.07 a thread plus $0.00665 a comment, LinkedIn $0.0035 a comment, X $0.0245 a thread plus $0.0007 a reply (inspect lists every platform). The hold covers the requested limit; the charge covers the comments returned. Reddit returns the comments only, not the post: read the post itself with social.post. If the provider's actual cost overruns the estimate, the run bills the overrun at the same per-call rate, capped by the hold.
The exact quote is returned by /v1/inspect before every call and held with headroom on execution. The quote is the price floor: if the provider's actual cost overruns it, the run bills the overrun at the same rate, never above the hold. The unused part of every hold is released.
