What is Claude Tool Use?
Anthropic's Claude API with tool use for building AI assistants that can call external APIs and functions.
Searching Google Ads Transparency with Claude Tool Use
This integration lets your Claude Tool Use agent search Google Ads Transparency in real time via the Scavio API. The agent gets back structured JSON with top_ads, bottom_ads, ad headlines, destination URLs -- ready for reasoning and decision-making.
Setup
Bash
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches Google Ads Transparency using Scavio:
Python
import anthropic
import json
import os
import requests
# Scavio has no Ads Transparency endpoint. This searches the public Ads Transparency Center pages through Google, which returns pages about the advertiser rather than the ad creatives themselves. For live ad copy on a keyword, read the top_ads and bottom_ads blocks of a POST /api/v2/google response instead.
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query Google Ads Transparency through the Scavio API (POST /api/v2/google)."""
response = requests.post(
"https://api.scavio.dev/api/v2/google",
headers={
"Authorization": "Bearer " + os.environ["SCAVIO_API_KEY"],
"Content-Type": "application/json",
},
json={"query": query},
timeout=60,
)
response.raise_for_status()
return json.dumps(response.json())
tools = [{
"name": "scavio_search",
"description": "Query Google Ads Transparency for real-time results",
"input_schema": {
"type": "object",
"properties": {"query": {"type": "string"}},
"required": ["query"],
},
}]
response = client.messages.create(
model="claude-sonnet-4-5",
max_tokens=4096,
tools=tools,
messages=[{"role": "user", "content": "google ads transparency center notion"}],
)
for block in response.content:
if block.type == "tool_use":
print(scavio_search(block.input["query"])[:500])
elif block.type == "text":
print(block.text)Full Working Example
