The builder

Add a node, wire it, fill its arguments, dry-run it. Saving is the first thing that asks you to sign in.

Document first

The canvas is a view of a small JSON document: nodes with a type and props, edges with a source handle. Every change goes into the document, which is what the API validates, runs and stores.

Read from an earlier step

A node’s argument can be a token such as steps.fetch.output.status. A whole-token value keeps its type, so an object flows through as an object rather than as text.
