250 credits / month

Credits measure the work an action does. A message, an email or a webhook is one credit; running your own code or handing the event to an AI agent is two. Agents run on your own model key, so you are never charged here for tokens.

250 credits covers any of:

  • 250alerts, emails or posts
  • 125code or AI agent runs
  • Covers your usage

About credit usage

Every action a flow runs uses credits, and not all of them cost the same. Delivering a message is cheap. Running your code, or handing the event to a model to reason about, costs more — because it costs us more.

One pool per account

Every workflow draws from the same monthly credits. There is no separate budget per workflow, per chain or per integration to keep in your head.

It scales with what you build

A Slack post costs one credit. Your own code, or an AI agent reading the event, costs two. You bring your own model key, so we charge for the orchestration and never for the tokens.

Relative cost per action

  • Slack, Email, Webhook

  • Decode, Token price

  • Transform, AI agent

Relative, not to scale. Exact rates live in the docs, and your usage is broken down per flow in the app.

Early access is open. Put your address in and you will be among the first to build a flow that watches the chain and acts on it.

  • Free while it is in early access
  • One email when it opens — nothing else
  • No card, no sales call
