Pay for what your flows do, not what the chain does.

Start with 1,000 credits a month. Watching, filtering and test runs never touch them.

How credits work

  • Triggers are free

    Watch and filter onchain events continuously. Nothing is charged for looking.

  • Actions use credits

    Credits are spent when a matching event actually reaches an action and it runs.

  • Test runs are free

    Build a flow and prove it works before it ever touches your allowance.

  • Pay for what runs

    Paid plans keep going past their included credits, billed by usage.

A month on one flow
  1. 10,000events watched
  2. 43match your filter
  3. 43actions run

Credits are charged here, and only here.

Pro covers it

Roughly 83 minutes of your flows actually running. One credit is about a second of work — an agent thinking costs more than a message being delivered.

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

It scales with what you build

A Slack post stays cheap. An agent call reasons over the event and costs more. You choose which steps a flow is worth.

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