Agent credits are what your AI agents spend when they run. Your plan grants a fresh allowance every month, and you can buy refill packs on top. Building agents costs nothing — only running them does. The Agent credits card at the top of the Agent Builder page shows your balance, a Top up button, and a Recent activity list of the last few grants, refills and runs.

What spends a credit

Two nodes, and only two: Agent and Classify. Everything else on the canvas — File search, Guardrails, MCP, If / else, While, User approval, Transform, Set state, End, Note — costs nothing at all. That makes the cost of a workflow easy to read off the canvas: count the Agent and Classify nodes a run will actually pass through. A branch the run does not take costs nothing.

Your monthly allowance

The two rules that decide what gets spent

  1. Monthly plan credits are always spent first. Refill packs are only touched once the month’s allowance runs out.
  2. Refill packs never expire. An unused pack carries over indefinitely, so buying ahead of a busy period is never wasted.

A schedule multiplies everything

This is where a small workflow becomes a large bill. The same two-step agent costs wildly different amounts depending on what starts it: An Every 15 minutes schedule on a two-step agent will exhaust a Team allowance on its own — before a second agent has run at all. A Public UI is the other multiplier: every visitor message is a run, which is why the abuse caps on publishing an agent matter. Sensible habits:
  • Use the slowest schedule that still meets the need. Most “overdue” work is fine on Every day.
  • Do the filtering in free nodes. Let If / else decide whether the run is worth an Agent step, rather than having the Agent step decide there was nothing to do.
  • Use Classify for sorting and a single Agent step for the writing, rather than several Agent steps in a row.
  • Watch Recent activity on the Agent credits card for the first few days after deploying anything scheduled.

Top up

Select Top up on the Agent credits card. The Top up agent credits dialog explains: “Refill packs never expire and are used after your monthly plan credits. You’ll complete payment securely on the next screen.” Choose a pack and you are taken to checkout.
Buying a refill pack charges your payment method immediately. Packs are not refundable once the credits land in your balance, so buy the size you will use — they never expire, but they also do not come back.

When you run out

Runs stop. A scheduled agent simply does not fire, and a public UI stops answering, until either your monthly allowance renews or you top up. Nothing is deleted and nothing needs re-deploying — the agent resumes on its next trigger once there is a balance.
