SKILL.md

Python SDK

Build AI applications with the inference.sh Python SDK.

Python SDK

Quick Start

bash
pip install inferencesh
python
from inferencesh import inference

client = inference(api_key="inf_your_key")

# Run an AI app
result = client.run({
    "app": "infsh/flux-1-dev",
    "input": {"prompt": "A sunset over mountains"}
})
print(result["output"])

Installation

bash
# Standard installation
pip install inferencesh

# With async support
pip install inferencesh[async]

Requirements: Python 3.8+

Authentication

python
import os
from inferencesh import inference

# Direct API key
client = inference(api_key="inf_your_key")

# From environment variable (recommended)
client = inference(api_key=os.environ["INFERENCE_API_KEY"])

Get your API key: Settings → API Keys → Create API Key

Running Apps

Basic Execution

python
result = client.run({
    "app": "infsh/flux-1-dev",
    "input": {"prompt": "A cat astronaut"}
})

print(result["status"])  # "completed"
print(result["output"])  # Output data

Fire and Forget

python
task = client.run({
    "app": "google/veo-3-1-fast",
    "input": {"prompt": "Drone flying over mountains"}
}, wait=False)

print(f"Task ID: {task['id']}")
# Check later with client.get_task(task['id'])

Streaming Progress

python
for update in client.run({
    "app": "google/veo-3-1-fast",
    "input": {"prompt": "Ocean waves at sunset"}
}, stream=True):
    print(f"Status: {update['status']}")
    if update.get("logs"):
        print(update["logs"][-1])

Run Parameters

Parameter Type Description
app string App ID (namespace/name@version)
input dict Input matching app schema
setup dict Hidden setup configuration
infra string 'cloud' or 'private'
session string Session ID for stateful execution
session_timeout int Idle timeout (1-3600 seconds)

File Handling

Automatic Upload

python
result = client.run({
    "app": "image-processor",
    "input": {
        "image": "/path/to/image.png"  # Auto-uploaded
    }
})

Manual Upload

python
from inferencesh import UploadFileOptions

# Basic upload
file = client.upload_file("/path/to/image.png")

# With options
file = client.upload_file(
    "/path/to/image.png",
    UploadFileOptions(
        filename="custom_name.png",
        content_type="image/png",
        public=True
    )
)

result = client.run({
    "app": "image-processor",
    "input": {"image": file["uri"]}
})

Sessions (Stateful Execution)

Keep workers warm across multiple calls:

python
# Start new session
result = client.run({
    "app": "my-app",
    "input": {"action": "init"},
    "session": "new",
    "session_timeout": 300  # 5 minutes
})
session_id = result["session_id"]

# Continue in same session
result = client.run({
    "app": "my-app",
    "input": {"action": "process"},
    "session": session_id
})

Agent SDK

Template Agents

Use pre-built agents from your workspace:

python
agent = client.agent("my-team/support-agent@latest")

# Send message
response = agent.send_message("Hello!")
print(response.text)

# Multi-turn conversation
response = agent.send_message("Tell me more")

# Reset conversation
agent.reset()

# Get chat history
chat = agent.get_chat()

Ad-hoc Agents

Create custom agents programmatically:

python
from inferencesh import tool, string, number, app_tool

# Define tools
calculator = (
    tool("calculate")
    .describe("Perform a calculation")
    .param("expression", string("Math expression"))
    .build()
)

image_gen = (
    app_tool("generate_image", "infsh/flux-1-dev@latest")
    .describe("Generate an image")
    .param("prompt", string("Image description"))
    .build()
)

# Create agent
agent = client.agent({
    "core_app": {"ref": "infsh/claude-sonnet-4@latest"},
    "system_prompt": "You are a helpful assistant.",
    "tools": [calculator, image_gen],
    "temperature": 0.7,
    "max_tokens": 4096
})

response = agent.send_message("What is 25 * 4?")

except RequirementsNotMetException as e:
    print(f"Missing requirements:")
    for err in e.errors:
        print(f"  - {err['type']}: {err['key']}")
except RuntimeError as e:
    print(f"Error: {e}")

Human Approval Workflows

python
def handle_tool(call):
    if call.requires_approval:
        # Show to user, get confirmation
        approved = prompt_user(f"Allow {call.name}?")
        if approved:
            result = execute_tool(call.name, call.args)
            agent.submit_tool_result(call.id, result)
        else:
            agent.submit_tool_result(call.id, {"error": "Denied by user"})
