What is Claude Tool Use?
Anthropic's Claude API with tool use for building AI assistants that can call external APIs and functions.
Searching Shopify with Claude Tool Use
This integration lets your Claude Tool Use agent search Shopify in real time via the Scavio API. The agent gets back structured JSON with store URLs, product page URLs, page titles, SERP snippets (price and stock text when Google shows it) -- ready for reasoning and decision-making.
Setup
Bash
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches Shopify using Scavio:
Python
import anthropic
import json
import os
import requests
# Scavio has no Shopify endpoint. This finds storefront pages through Google; prices and variants come from the pages you then fetch yourself.
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query Shopify 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 Shopify 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": "site:myshopify.com leather wallet"}],
)
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
