FAQ

Questions about Message with Web Search.

What does the Message with Web Search action do in Anthropic?

Sends a message with Anthropic's built-in web_search tool enabled. Claude fetches fresh web results inside the model call and cites them in the response. Removes the need to wire up an external search API.

What inputs does Message with Web Search require?

Required: Model, Question. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Anthropic returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Message with Web Search support batch operations?

Yes. Run Message with Web Search inside a Loop node to process arrays. Tiny Command handles Anthropic's rate limits automatically so you don't have to throttle manually.
