What is Claude Tool Use?
Anthropic's Claude API with tool use for building AI assistants that can call external APIs and functions.
How It Works
Scavio connects to Claude Tool Use via a custom tool definition. Once connected, your Claude Tool Use agent can search Google, Amazon, YouTube, and Walmart in real time. Each search returns structured JSON — no HTML parsing, no scraping infrastructure.
Setup
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use integration with Scavio:
import anthropic
import requests
import json
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
response = requests.post(
"https://api.scavio.dev/api/v1/search",
headers={"x-api-key": "your_scavio_api_key", "Content-Type": "application/json"},
json={"query": query},
)
return json.dumps(response.json())
response = client.messages.create(
model="claude-sonnet-4-20250514",
max_tokens=4096,
tools=[{
"name": "scavio_search",
"description": "Search the web for real-time results",
"input_schema": {
"type": "object",
"properties": {"query": {"type": "string"}},
"required": ["query"],
},
}],
messages=[{"role": "user", "content": "Find the best noise cancelling headphones"}],
)
for block in response.content:
if block.type == "tool_use":
result = scavio_search(block.input["query"])
print(result[:500])
elif block.type == "text":
print(block.text)Full Working Example
A production-ready example with error handling:
import anthropic
import requests
import json
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
response = requests.post(
"https://api.scavio.dev/api/v1/search",
headers={"x-api-key": "your_scavio_api_key", "Content-Type": "application/json"},
json={"query": query},
)
return json.dumps(response.json())
tools = [{
"name": "scavio_search",
"description": "Search the web for real-time results",
"input_schema": {
"type": "object",
"properties": {"query": {"type": "string"}},
"required": ["query"],
},
}]
messages = [{"role": "user", "content": "Find the best noise cancelling headphones"}]
response = client.messages.create(model="claude-sonnet-4-20250514", max_tokens=4096, tools=tools, messages=messages)
# Handle tool use loop
if response.stop_reason == "tool_use":
messages.append({"role": "assistant", "content": response.content})
tool_results = []
for block in response.content:
if block.type == "tool_use":
result = scavio_search(block.input["query"])
tool_results.append({"type": "tool_result", "tool_use_id": block.id, "content": result})
messages.append({"role": "user", "content": tool_results})
final = client.messages.create(model="claude-sonnet-4-20250514", max_tokens=4096, tools=tools, messages=messages)
print(final.content[0].text)Available Platforms
Once connected, your Claude Tool Use agent has access to all four Scavio platforms:
