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 advertiser_id and region_code, total_ads range, creative_id and preview URLs, first_shown, last_shown, days_shown -- ready for reasoning and decision-making.
Setup
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches Google Ads Transparency using Scavio:
import anthropic
import json
import os
import requests
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query Google Ads Transparency through the Scavio API (POST /api/v1/googleads/advertisers)."""
response = requests.post(
"https://api.scavio.dev/api/v1/googleads/advertisers",
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": "Nike"}],
)
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
