# Blueprint

**Badge:** Blueprint  
**Node type:** `blueprint:invoke`  
**Category:** `process`

## Description

Invoke a published Blueprint as a collapsed subworkflow. Its inputs become node ports on the left, its outputs become ports on the right. At execution time, the Blueprint runs as a child execution and pipes its results back into this graph.

## Pricing

- **Cost:** this node itself costs no credits

## Canvas ports

These appear as port handles on the left side of the node.

_No input ports._

## Sidebar config

These render as form fields in the right-side config panel when the node is selected.

_No sidebar config fields._

## Outputs

_No outputs._

## Ports are per instance, not fixed

The tables above are empty because the registry entry is a shell. A real
Blueprint node gets its ports when you add it: every input node in the
Blueprint becomes a port on the left, every leaf output becomes a port on the
right. Two nodes pointing at different Blueprints have completely different
shapes, so there is no fixed port list to document here. Open the node on the
canvas to see its actual ports.

## Add it from the Blueprint's page

Press **Add to workflow** on a Blueprint's page. That route is the only thing
that computes the ports and the blueprint id together. A node built by hand
arrives with zero handles, can be wired to nothing, and fails at run time.

## Credits

The node itself is free. The Blueprint's constituent nodes bill individually
against the parent run's user as the child execution runs, so the cost is
whatever the inside of that Blueprint costs. There is no separate child run to
open: the internals do not get their own execution record yet, so per-step
timings and results for them are not shown.
