Plan Pricing

Two flat-rate plans selected per API call via the plan parameter:

Plan	Rate	Features
Pro (`plan=pro`)	$0.39/hr	Full 11-feature AI analysis JSON (summary, sentiment, compliance, financial, action_items, transcript_cleaned, optional features)
Lite (`plan=lite`)	$0.15/hr	Transcript, diarization, and `transcript_cleaned` only

Example: 1,000 hours on Pro = $390. 1,000 hours on Lite = $150. Same rate regardless of volume — no graduated tiers.

Per-call billing: Each API call is billed individually based on the audio duration. The rate applied depends on the plan parameter used in your transcription request (pro or lite).
