Every node in the catalog

The full authored palette: 42 node types in 10 groups, 24 of them free on the platform side and 9 carrying a fixed USDC estimate. This page is derived from the same catalog module the studio ships (src/lib/flow/node-definitions.ts), so when the palette grows, this reference updates itself.

How to read the tables

Four columns, no surprises

Dry run is what the node does in the default free mode. “Runs for real” means the node executes its actual logic in a dry run because it costs nothing and reaches nothing external on its own. “Stubbed” means the engine intercepts the node before its executor runs and returns a placeholder in the real output shape: no money moves, no external system is touched.

Effects are the node's declared capabilities: what it can read, write, send, spend, publish, or settle. A dash means the node is pure local computation. Subflow and Loop declare every effect because they run another flow: their true effects are whatever the inner flow contains, and the engine budgets them accordingly.

Cost is the platform-side price. “Variable” covers three honest cases: AI nodes metered in gateway tokens, HTTP-shaped nodes whose real cost is whatever the target service bills you, and Subflow/Loop whose cost is the sum of what runs inside them. Fixed estimates are per call, in USDC, and shown on the node card in the palette too. The pricing model behind all of this is documented in Payments.

Field-level detail for the four general-purpose workhorses (HTTP, Webhook, Transform, Loop), including caps, the SSRF guard, and the expression grammar, lives on the quick reference.

One honest footnote

Catalog versus palette

This page lists the complete authored catalog, including the Connector Lab's API Operation prototype, which is simulation-only and cannot be launched into a live agent (the launch API rejects graphs that contain it). The palette you see in the studio can additionally gate nodes by availability, so a node listed here may not be offered to every workspace yet. When in doubt, the palette in your own studio is the truth for your account; this page is the truth for what exists.
