Step 2: Set up Required Libraries
When you’re utilizing Python, set up the required libraries:
pip set up anthropic
Step 3: Make an API Name
A primary instance of querying Claude:
import anthropic
shopper = anthropic.Anthropic()
message = shopper.messages.create(
mannequin="claude-3-7-sonnet-20250219",
max_tokens=1000, temperature=1,
system="You're a world-class poet. Reply solely with quick poems.",
messages=[
{
"role": "user",
"content": [
{
"type": "text",
"text": "Why is the ocean salty?"
}
]
}
]
)
print(message.content material)
This API name sends a question and retrieves Claude’s response in actual time.
Step 4: Fantastic-Tune for Your Use Case
Builders can optimize API calls by:
- Adjusting temperature settings for creativity.
- Enabling prolonged reasoning for complicated queries.
- Utilizing structured prompts for higher accuracy.

Testing Claude 3.7 Sonnet’s API Capabilities
Now, let’s take a look at Claude with real-world eventualities:
Check 1: Picture Evaluation – IND vs PAK Cricket Match
For instance from an India vs Pakistan Champions trophy match,Claude will probably be proven a picture and requested to supply essential particulars.
- Figuring out gamers, stadium, and occasion particulars.
- Summarizing the match state of affairs (e.g., “India is batting with 5 wickets down within the last overs”).
- Extracting textual content from scoreboards.
Enter Picture:

Enter Code :
import anthropic
shopper = anthropic.Anthropic()
message = shopper.messages.create(
mannequin="claude-3-7-sonnet-20250219",
max_tokens=1024,
messages=[
{
"role": "user",
"content": [
{
"type": "image",
"source": {
"type": "base64",
"media_type": image1_media_type,
"data": image1_data,
},
},
{
"type": "text",
"text": "You are analyzing an image from the India vs Pakistan Champions Trophy 2025 match. "
"Extract and summarize the most relevant insights in the following structured order:nn"
"1️⃣ **Match Overview**: Identify the teams, tournament, stadium, and year.n"
"2️⃣ **Key Players**: Recognize any visible players based on jerseys, number, and positioning.n"
"3️⃣ **Match Context**: Determine which team is batting, the current score, overs, and any visible scoreboard data.n"
"4️⃣ **Text Extraction**: If a scoreboard or banners are visible, extract relevant text (e.g., scores, team names, advertisements).n"
"5️⃣ **Atmosphere & Crowd**: Describe the overall scene (e.g., crowd intensity, celebrations, flags, banners).n"
"6️⃣ **Highlight Events**: Identify any key moments such as a boundary, wicket, appeal, or fielder's action.nn"
"⚠️ **Ensure factual accuracy by only describing visible elements. Avoid assumptions.**"

Check 2: Downside-Fixing with Logical Reasoning
We set the problem of a multi-stage downside for Claude:
“A practice leaves New York heading towards Chicago at 80 mph. One other practice leaves Chicago for New York at 70 mph. They’re 800 miles aside. When do they meet?”
Claude will break down the issue utilizing step-by-step logical reasoning.
Enter Code:
output = anthropic.Anthropic().messages.create(
mannequin="claude-3-7-sonnet-20250219",
max_tokens=1024,
messages=[
{"role": "user",
"content": """
A train leaves New York heading toward Chicago at 80 mph.
Another train leaves Chicago for New York at 70 mph.
They are 800 miles apart. When do they meet?
"""
}
]
)
show(Markdown(output.content material[0].textual content))
Output:

Check 3: HTML Animation – Bouncing Ball Simulation
Subsequent, we’re going to invite Claude to supply some HTML animation:
“Write an HTML CSS+JavaScript program, simulating a ball that bounces inside a sequence of nested circles; every circle has a gap. Every time the ball touches a restrict, the within opens after which the ball follows gravity and momentum.”
This take a look at will show Claude’s means to:
- Generate useful, interactive net code.
- Simulate physics-based animations.
- Guarantee right logic and syntax in HTML/CSS/JS.
Code Enter:
output = anthropic.Anthropic().messages.create(
mannequin="claude-3-7-sonnet-20250219",
max_tokens=1024,
messages=[
{"role": "user",
"content": """
Write an HTML CSS+JavaScript program, simulating a ball that
bounces inside a circle;
the ball follows gravity and momentum.
"""
}
