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 Reviews with Claude Tool Use
This integration lets your Claude Tool Use agent search Google Reviews in real time via the Scavio API. The agent gets back structured JSON with review text, star rating, reviewer profile, review date -- ready for reasoning and decision-making.
Setup
Bash
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches Google Reviews using Scavio:
Python
import anthropic
import json
import os
import requests
# Reviews are per place: get a data_id (or place_id) from POST /api/v2/google/maps/search first. Owner responses are not part of this response.
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query Google Reviews through the Scavio API (POST /api/v2/google/maps/reviews)."""
response = requests.post(
"https://api.scavio.dev/api/v2/google/maps/reviews",
headers={
"Authorization": "Bearer " + os.environ["SCAVIO_API_KEY"],
"Content-Type": "application/json",
},
json={"data_id": query, "num": 10, "sort_by": "newest"},
timeout=60,
)
response.raise_for_status()
return json.dumps(response.json())
tools = [{
"name": "scavio_search",
"description": "Query Google Reviews 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": "0x89c259869319e7af:0x54953953a5ede7bb"}],
)
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
