Call Actor
call-actorExecute any Actor from the Apify Store dynamically. Provide the actor name and input, with optional memory, timeout, and wait settings.
Instructions
Call any Actor from the Apify Store.
WORKFLOW:
Use fetch-actor-details to get the Actor's input schema
Call this tool with the actor name and proper input based on the schema
If the actor name is not in "username/name" format and search-actors is available in this session, use it to resolve the correct Actor first.
For MCP server Actors:
Use fetch-actor-details with output={ mcpTools: true } to list available tools
Call using format: "actorName:toolName" (e.g., "apify/actors-mcp-server:fetch-apify-docs")
IMPORTANT:
Waits up to waitSecs (default 30s) for completion; returns run status, storage IDs, and field metadata
Use get-dataset-items with the datasetId to fetch results; non-terminal runs include a nextStep with polling instructions
Use dedicated Actor tools when available for better experience
There are two ways to run Actors:
Dedicated Actor tools (e.g., apify--rag-web-browser): These are pre-configured tools, offering a simpler and more direct experience.
Generic call-actor tool (call-actor): Use this when a dedicated tool is not available or when you want to run any Actor dynamically. This tool is especially useful if you do not want to add specific tools or your client does not support dynamic tool registration.
USAGE:
Always use dedicated tools when available (e.g., apify--rag-web-browser)
Use the generic call-actor tool only if a dedicated tool does not exist for your Actor.
Use
waitSecs(0–45) to control how long to wait. Default 30s returns results for fast actors. UsewaitSecs: 0to start and return immediately for long-running actors.
EXAMPLES:
user_input: Get instagram posts using apify/instagram-scraper
