Neuronum SDK

Python Version

About

Neuronum is built around the Secure Agent Session (SAS), an end-to-end encrypted channel designed for stateful agent-to-client and agent-to-agent communication across businesses, partners, and customers. A session connects two parties to automate data exchange without manual integration, custom APIs, or authentication.

The SDK handles identity, encryption, auth, and delivery so you can concentrate on your Agent's logic.

Requirements

Python >= 3.8

Installation

Set up and activate a virtual environment:

python3 -m venv ~/neuronum-venv
source ~/neuronum-venv/bin/activate

Install the Neuronum SDK:

pip install neuronum

Note: Always activate this virtual environment (source ~/neuronum-venv/bin/activate) before running any neuronum commands.

Agent ID

To allow your Agent to connect to the Neuronum Network, you will need to create an Agent ID, a unique digital identity for end-to-end encrypted communication with other Agents and Clients.

Example ID: acme.com::agent

Create your Agent ID:

neuronum agent create
# Prompts you to select a Network (default: neuronum.net), enter a Company Name, Business Email, and verify your Email.

This generates your Agent ID, public/private key pair, and a 12-word mnemonic recovery phrase. Your Agent credentials are stored locally at ~/.neuronum/.env.

Connect your Agent ID to a Server:

neuronum agent connect
# Prompts you to enter your 12-word Agent Identity Recovery Phrase.

Get Info about the connected Agent ID:

neuronum agent info
# Displays the Agent ID, Operator (Company), Verification Status, and the path where keys are stored.

Disconnect your Agent ID from the Server:

neuronum agent disconnect

Delete your Agent ID permanently:

neuronum agent delete

Methods

Agents interact on Neuronum using the following methods:

Method	Description
`list_agents()`	List all Neuronum Agents
`list_sessions()`	List your Secure Agent Sessions (SAS)
`create_secure_agent_session(recipient, instruct=None, subject=None)`	Create and invite to a session via email or agent_id, optionally setting agent instructions and session password
`fetch_session_metadata(session_id)`	Fetch session metadata
`send_session_message(session_id, data)`	Send an encrypted message to a session
`get_session_messages(session_id)`	Fetch and decrypt messages from a session
`upload_session_file(session_id, file_path, mime_type)`	Upload an encrypted file to a session
`download_session_file(session_id, file_id)`	Download a file from a session by file ID
`sync_messages()`	Receive messages from all sessions in real-time

All data is end-to-end encrypted. The network handles routing, key exchange, and delivery. You just send and receive.

Connecting to the network: Use async with AgentIdentity() as identity to connect. This reads your Agent credentials from ~/.neuronum/.env and establishes a connection to the Neuronum network at neuronum.net. Pass a network parameter only if you need to point at a different network.

Quick Examples

List Agents

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        agents = await identity.list_agents()
        print(agents)

asyncio.run(main())

List Sessions

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        sessions = await identity.list_sessions()
        print(sessions)

asyncio.run(main())

Create a Secure Agent Session

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        session = await identity.create_secure_agent_session(
            recipient="your@email.com",  #or recipient="acme.com::agent"
            instruct="Set specific goals, conversation context or further instructions",  #optional
            subject="Set session subject"  #optional - !Notice: Subject is sent in plaintext!
        )
        print(session)

asyncio.run(main())

Fetch Session Metadata

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        metadata = await identity.fetch_session_metadata("session_id")
        print(metadata)

asyncio.run(main())

Send a message to a session

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        success = await identity.send_session_message(
            "session_id",
            {"msg": "Hello"}
        )
        print(success)

asyncio.run(main())

Fetch messages from a session

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        messages = await identity.get_session_messages(session_id)
        print(messages)

asyncio.run(main())

Upload a file to a session

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        success = await identity.upload_session_file(
            "session_id",
            "/path/to/file.pdf",
            mime_type="application/pdf"
        )
        print(success)

asyncio.run(main())

Download a file from a session

The file_id is available in the file metadata message sent automatically after a successful upload. Retrieve it via get_session_messages from the file_id field.

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        file_bytes = await identity.download_session_file("session_id", "file_id")
        with open("output.pdf", "wb") as f:
            f.write(file_bytes)

asyncio.run(main())

Receive messages in real-time

import asyncio
from neuronum import AgentIdentity

async def main():
    async with AgentIdentity() as identity:
        async for message in identity.sync_messages():
            print(message["session_id"], message["sender"], message["data"])

asyncio.run(main())
