What is Claude Tool Use?
Anthropic's Claude API with tool use for building AI assistants that can call external APIs and functions.
Searching Reddit with Claude Tool Use
This integration lets your Claude Tool Use agent search Reddit in real time via the Scavio API. The agent gets back structured JSON with posts, comments, subreddits, authors -- ready for reasoning and decision-making.
Setup
Bash
pip install anthropic requestsCode Example
Here is a complete Claude Tool Use agent that searches Reddit using Scavio:
Python
import anthropic
import json
import os
import requests
# Reddit search takes query and an optional cursor only - there is no sort parameter here. For sorted feeds use POST /api/v1/reddit/subreddit/posts.
client = anthropic.Anthropic()
def scavio_search(query: str) -> str:
"""Query Reddit through the Scavio API (POST /api/v1/reddit/search)."""
response = requests.post(
"https://api.scavio.dev/api/v1/reddit/search",
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 Reddit 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": "best python web frameworks 2026"}],
)
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
