# Flows · Authoring · List the step types a diagram can use

GET https://api.simplified.com/api/v1/workflows/actions

Lists the workflow step types a diagram can use — around 250 blocks covering
AI text and image generation, video and audio editing, PDF tools, HTTP calls,
Slack and email, PM tasks, and control flow.

**Pass `search`.** `page_size` is capped at 100 server side whatever you ask
for, and larger values can return 503. This endpoint also 503s intermittently
— retry before concluding it is broken.

Per row, the fields that matter for placing a block in a diagram:

* `slug` — the action's identifier, used in a block's `data.reference`
* `schema.config.dataSchema.properties.inputParameters` — accepted fields and
  which are `required`
* `schema.exampleResult` — the output shape, which determines which output
  paths a later step can reference
* `consumes_credits` — whether running it bills the workspace

⚠️ Some required fields declare only `{"type": "string"}` and draw their valid
values from a live endpoint named in `uiSchema` as `ui:optionsUrl` (with
`ui:widget: selectAsync`). Inventing a value for one of those yields a
workflow that looks right and misbehaves.

`resource: workflow://diagram-grammar` covers how to resolve those fields.
`resource: workflow://actions` is a compact index of the whole palette.

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key   `) — Header authentication of the form `Api-Key  <token>`
- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Query parameters

- `search` (string, optional) — Substring match over slug, title and description.
- `page` (integer, optional) — 1-based page number.
- `page_size` (integer, optional) — Results per page. Capped at 100 server side.

## Response

### 200

Paginated list of action blocks with their schemas.

## Errors

### 503 Service Unavailable Error

Transient. Retry, and reduce `page_size` if it was above 100.

- `any`
