Serper Search

Search Google and get the top results.

What it does

A straight web search, cheap and fast, returning what a search engine would show. The default choice when an agent needs to look something up.

What you need

API key from Serper. serper.dev → Dashboard. The free tier is enough to try it.

Connecting it

Credentials belong to one project, not to your workspace and not to you. A system built for one client never runs on another client's account, and a package handed to a business runs on theirs.

Open the project and stay on the Visual Editor tab.
Open the Tools & Integrations rail on the right.
Find this tool, open it, and paste the credential.

To change it later, open the same panel — you can leave the key blank to keep the stored one and change only the other field.

Using it in a step

An Action step runs one tool with the arguments you type, exactly as written, with no model involved — so it costs nothing per run and behaves the same every time. Add one from the canvas toolbar, choose Serper Search, and fill in:

Field	Required	What goes in it
`query`	yes	What you would type into a search engine.
`count`	no	How many results.

Values can carry results forward: {{previous}} is the step before, and {{row:column}} is a column from the row this run is about when the trigger fans out.

Press Try it to run the step on its own before committing to a whole sequence.

Using it with an agent

Tick Serper Search on any agent that should be able to call it, and the agent decides when to. Use an agent when the judgement matters and an Action step when the certainty does.

A worked example

An agent verifying a supplier searches the company name plus 'RC number' and reads back the first few results before deciding whether to trust an invoice.

When it goes wrong

Too many results, little substance. Search returns snippets. If the agent needs the actual page, pair it with Scrape Website.
