Python SDK Quickstart

Get up and running with the MutagenT Python SDK in minutes.

​
Prerequisites

  • Python 3.10+
  • pip install mutagent-sdk
  • A MutagenT API key — set as MUTAGENT_API_KEY in your environment

​
Create a Prompt

from mutagent import Mutagent
from mutagent.models import NameDescriptionVersion

client = Mutagent()

# Create a new prompt
prompt = client.prompt.create_prompt(NameDescriptionVersion(
    name="Support Assistant",
    raw_prompt="You are a helpful assistant for {company}. Answer questions about {topic}.",
    input_schema={"type": "object", "properties": {"company": {"type": "string"}, "topic": {"type": "string"}}},
))

print(f"Created: {prompt.id}")
print(f"Name: {prompt.name}")

​
List Prompts

from mutagent import Mutagent

client = Mutagent()

result = client.prompt.list_prompts()
for p in result.get("data", []):
    print(f"  {p['id']}: {p['name']}")

​
Get a Specific Prompt

# id_ is a numeric prompt ID (integer)
prompt = client.prompt.get_prompt(id_=123)
print(prompt["name"], prompt.get("raw_prompt") or prompt.get("human_prompt"))

​
Async Version

The same operations work with AsyncMutagent in async contexts: 
import asyncio
from mutagent import AsyncMutagent

async def main():
    async with AsyncMutagent() as client:
        # Create a prompt
        from mutagent.models import NameDescriptionVersion
        prompt = await client.prompt.create_prompt(NameDescriptionVersion(
            name="Support Assistant",
            raw_prompt="You are a helpful assistant for {company}.",
            input_schema={"type": "object", "properties": {"company": {"type": "string"}}},
        ))
        print(f"Created: {prompt['id']}")

        # List all prompts
        result = await client.prompt.list_prompts()
        print(f"Total prompts: {len(result.get('data', []))}")

asyncio.run(main())

​
Error Handling

All API errors raise MutagentError with the HTTP status code, response body, and headers: 
from mutagent import Mutagent
from mutagent.errors import SDKError

client = Mutagent()

try:
    prompt = client.prompt.get_prompt(id_=999999)  # nonexistent ID
except SDKError as e:
    print(f"Status: {e.status_code}")
    print(f"Body: {e.body}")

​
Retries

The SDK automatically retries transient failures (429, 5xx) with exponential backoff (250ms → 500ms → 1s → 2s → 4s, 3 retries by default). The retry logic is built in and requires no configuration. Configure the timeout at construction time: 
client = Mutagent(
    api_key="mt_xxxxxxxxxxxx",
    timeout=30.0,   # seconds (default: 60)
)
