What is Claude Tool Use?
Anthropic's Claude API with tool use for building AI assistants that can call external APIs and functions.
Searching YouTube Shorts with Claude Tool Use
This integration lets your Claude Tool Use agent search YouTube Shorts in real time via the Scavio API. The agent gets back structured JSON with short video results, video ids, view counts, published time -- ready for reasoning and decision-making.
Setup
Bash
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches YouTube Shorts using Scavio:
Python
import anthropic
import json
import os
import requests
# Shorts search takes search (not query). channel.name is often empty on Shorts rows - resolve it with POST /api/v1/youtube/video when you need it.
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query YouTube Shorts through the Scavio API (POST /api/v1/youtube/shorts)."""
response = requests.post(
"https://api.scavio.dev/api/v1/youtube/shorts",
headers={
"Authorization": "Bearer " + os.environ["SCAVIO_API_KEY"],
"Content-Type": "application/json",
},
json={"search": query},
timeout=60,
)
response.raise_for_status()
return json.dumps(response.json())
tools = [{
"name": "scavio_search",
"description": "Query YouTube Shorts 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": "ai coding agent shorts"}],
)
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
