How billing works

Rule	Detail
Unit of billing	1 token = 1 second of audio
Price	$0.10 per minute of audio
Minimum charge	1 token per job
crop_audio	Free, no token charge
Batch API	Paid keys only (free keys are rejected)
Free grant	One-time 300-token grant on a free key
Top-ups	Prepaid, $10 minimum, one-time, not a monthly plan

A token maps directly to a second of audio, so a three-minute track costs 180 tokens, about thirty cents. Every job charges at least one token, and identical audio you resubmit within your own account is analyzed once and never re-charged.

Starting free

300 free tokens. A free key comes with a one-time 300-token grant, enough to run real jobs before you spend anything.

1 TB free storage. Your audio library comes with a full terabyte of storage at no cost, kept while your account is active, the same on every tier.

Prepaid, made easy

Pay as you go

Top-ups are prepaid: you buy tokens up front (a $10 minimum) and they don't expire on a billing cycle. To make prepaid effortless, a few conveniences are available:

Saved cards, low-balance alerts, and auto-recharge. Save a payment method, get an email when your balance runs low, and optionally auto-top-up when it does. These are prepaid conveniences: automatic top-up is a one-time purchase you opt into, not a monthly plan.

What paid unlocks

The per-second price is the same for everyone: paid tiers gate scale, not features. Paying unlocks higher concurrency and throughput and the batch API, which is paid-only. Storage is a full terabyte free on every tier, and the capabilities themselves are the same across tiers.
