The free tier is fully functional for exploring DECODA. You get 10 Ask queries and 3 Agent analyses per month — enough to try every feature.

​
What Counts as Usage

  • Ask query — Each message sent in Ask mode counts as one query
  • Agent analysis — Each message sent in Agent mode counts as one analysis, regardless of how many tools the agent runs
Usage resets at the start of each billing period.

​
Credit System

When you exceed your tier’s monthly limits, you can continue analysing with credits. Credits are available on Analyst and Professional tiers only.

​
Credit Packs

PackPricePer Credit
5 credits$7.50$1.50
15 credits$18.75$1.25Most Popular
30 credits$27.00$0.90Best Value

​
How Credits Work

  1. You send a message that would exceed your monthly limit
  2. DECODA checks if you have available credits
  3. One credit is deducted for the query (Ask or Agent)
  4. Your analysis proceeds normally
Credits never expire and carry over between billing periods. They are only consumed when your monthly allocation is exhausted.

​
Credit Safety

DECODA uses a fail-closed billing model. If there’s any issue checking your quota or deducting credits, the request is denied rather than allowed. This prevents accidental overuse.

​
Managing Your Subscription

You can manage your subscription from Settings > Billing:
  • View current usage — See how many Ask queries and Agent analyses you’ve used this period
  • Purchase credits — Buy credit packs for additional capacity
  • Change plan — Upgrade or downgrade your subscription
  • Billing portal — Access invoices and payment method management via Paddle

​
Upgrading

When you upgrade, the new limits take effect immediately. Your usage count carries over for the current period.

​
Downgrading

When you downgrade, the change takes effect at the end of your current billing period. You keep your current tier’s limits until then.
