Credit

how does credit consuption works? 1 credit = 1 user message? Yesterday I tested just one API block but over 12000 credits were consumed. Could you help me understand why this happened? If API blocks dont consume credits I’d like to request a refund for the credits used.

Hi there! Here’s a quick recap of how credits are counted and why you might see a big spike.

What costs credits in a chat agent
• 1 user-sent chat message = 1 credit
• Agent messages, API blocks, function blocks, logic steps = 0 credits
• LLM calls (GPT-4, Claude, etc.) = credits based on tokens used (see pricing table).

So if you only clicked “Run” once and typed one message, that would normally be just 1 credit plus whatever the LLM spent to generate answers.

Why 12 000 credits could appear
12 000 credits ≈ 600 USD of usage. The two most common causes are:

A loop in your flow that repeatedly hit an LLM prompt.
Example: GPT-4-turbo (2.5 credits / 1 k tokens). 12 000 credits ≈ 4.8 M tokens – that can happen fast if a loop runs for minutes.
You accidentally ran a voice test – voice minutes are 10 credits each, so a 20-min call = 200 credits.

How to verify

Open the project ➜ Analytics ➜ “Credits usage” chart.
Expand the day in question – you’ll see a breakdown by feature (chat, voice) and by model (GPT-4, GPT-4o-mini, Claude, etc.).
Cross-check which step in your flow fired the model/API repeatedly.

Next steps
• If you find a loop, add exit conditions or move the LLM prompt outside the loop.
• To avoid surprises while testing, use cheaper models (GPT-3.5, Gemini Flash) or switch LLM blocks off until the logic is stable.
• You can also set hard credit limits for the workspace to stop the agent when the limit is reached.

Docs for reference:
• Credits overview – https://docs.voiceflow.com/docs/credits
• Pricing table – https://docs.voiceflow.com/docs/credits-pricing-table

Hope this clarifies what happened! Once you’ve looked at the analytics breakdown you’ll know exactly which block consumed the credits and can adjust accordingly.

Hey @matcastro, could you share more details here? That is highly unlikely, that would be nearly $60 of OpenAI usage for a single call

Braden•7/14/25, 10:48 PM

Are you looking at tokens in the debug logs?

I had to delete the agent so my credits would not be consumed

matcastroOP•7/14/25, 10:56 PM

And the only block that i had is an api call

Braden•7/15/25, 3:45 AM

Got it, do you have any screenshots or anything? Hard to go off this and see what happened, it's just super unlikely so would want to see what happeend

Braden•7/15/25, 3:59 AM

can you share your VF email? our support team will pull the logs and see what happened

I dont have any screenshots bacause i had to delete the agent very quickly

matcastroOP•7/15/25, 2:06 PM

Thanks very much braden

Braden•7/15/25, 2:22 PM

what project is this....

Braden•7/15/25, 2:22 PM

i think this is the most agents i've ever seen haha :p 1500+ agents

Braden•7/15/25, 2:22 PM

honestly it might not be 1 API call, but looking at the totals - they aren't real-time and update every few minutes

The project was Eccomerce - Recuperação de Vendas (COPY)

matcastroOP•7/15/25, 4:54 PM

But was deleted

matcastroOP•7/15/25, 4:54 PM

Sunday night

Braden•7/15/25, 4:59 PM

Got it

Braden•7/15/25, 4:59 PM

I'll DM you
