mech-client 0.2.14

Basic client to interact with a mech

Mech Client

A basic client to interact with an AI Mech. AI Mechs allow users to post requests for AI tasks on-chain, and get their result delivered.

:warning: Warning
This is a hacky alpha version of the client. Don't rely on it as production software.

Requirements

• Python >=3.10

Installation

Find the latest available release on PyPi.

We recommend that you create a virtual Python environment using Poetry. Set up your virtual environment as follows:

poetry new my_project
cd my_project
poetry shell
poetry add mech-client

Alternatively, you can also install the Mech Client in your local Python installation:

pip install mech-client

If you require to use the Mech Client programmatically, please see this section below.

Set up the EOA and private key

To use the Mech Client you need an EOA account and its associated private key stored in a text file ethereum_private_key.txt. You can set it up in two ways:

• Use any software of your choice (e.g., Metamask) and copy the private key:

  echo -n YOUR_PRIVATE_KEY > ethereum_private_key.txt
  

  Do not include any leading or trailing spaces, tabs or newlines, or any other character in the file ethereum_private_key.txt.

• Alternatively, use the Open AEA command generate-key (you'll need to install Open AEA and its Ethereum ledger plugin):

  aea generate-key ethereum
  

  and display the corresponding EOA:

  python -c "from web3 import Web3; print(Web3().eth.account.from_key(open('ethereum_private_key.txt').read()).address)"
  

The EOA you use must have enough funds to pay for the Mech requests, or alternatively, use a Nevermined subscription.

:warning: Warning

• If the generated EOA account is for development purposes, make sure it does not contain large amounts of funds.

• If you store the key file in a local Git repository, we recommend that you add it to .gitignore in order to avoid publishing it unintentionally:

  echo ethereum_private_key.txt >> .gitignore
  

Select the mech you are going to send requests to

Mechs are deployed to several networks. Find the list of supported networks and corresponging mech addresses here.

Generate Mech requests

The basic usage of the Mech Client is as follows:

mechx interact <prompt> <agent_id>

where agent with <agent_id> will process <prompt> with the default options. Each chain has its own set of Mech agents. You can find the agent IDs for each chain on the Mech Hub or on the Mech repository.

Some useful options:

• --key <private_key_path>: Specifies the path of the private key. The default value is ./ethereum_private_key.txt.

• --tool <name>: Name of the tool to process the prompt. If you are aware about the tools that are provided by an agent you can directly provide its name using this option. If not provided, it will show a list of available tools for the agent so that you can select which one you want to use:

  Select prompting tool
  |--------------------------------------------------|
  | ID | Tool                                        |
  |--------------------------------------------------|
  | 0  | openai-text-davinci-002                     |
  | ...| ...                                         |
  |--------------------------------------------------|
  Tool ID >
  

• --chain-config <name>: Use default chain configuration parameters (RPC, WSS, ...). See below for more details. Available values are

  • arbitrum
  • base
  • celo
  • gnosis (Default)
  • optimism
  • polygon

• --confirm <type>: Specify how to wait for the result of your request:

  • off-chain: Wait for the result using the ACN.
  • on-chain: Wait for the result using the Subgraph and the Websocket subscription (whichever arrives first).
  • wait-for-both (Default): Wait for the result using both off-chain and on-chain (whichever arrives first).

Example

Example of a request specifying a key file and tool:

mechx interact "write a short poem" 6 --key ~/ethereum_private_key.txt --tool openai-gpt-3.5-turbo --chain-config gnosis --confirm on-chain

You will see an output like this:

Chain configuration: gnosis

:pencil2: Note
If you encounter an "Out of gas" error when executing the Mech Client, you will need to increase the gas limit, e.g.,

export MECHX_GAS_LIMIT=200000

Chain configuration

Default configurations for different chains are stored in the file configs/mechs.json. If --chain-config parameter is not specified, the Mech Client will choose the first configuration on the JSON.

Additionally, you can override any configuration parameter by exporting any of the following environment variables:

MECHX_CHAIN_RPC
MECHX_WSS_ENDPOINT
MECHX_GAS_LIMIT
MECHX_CONTRACT_ABI_URL
MECHX_TRANSACTION_URL
MECHX_SUBGRAPH_URL

MECHX_LEDGER_ADDRESS
MECHX_LEDGER_CHAIN_ID
MECHX_LEDGER_POA_CHAIN
MECHX_LEDGER_DEFAULT_GAS_PRICE_STRATEGY
MECHX_LEDGER_IS_GAS_ESTIMATION_ENABLED

Programmatic usage

You can also use the Mech Client as a library on your Python project.

1. Set up the private key as specified above. Store the resulting key file (e.g., ethereum_private_key.txt) in a convenient and secure location.

2. Create Python script my_script.py:

   touch my_script.py
   

3. Edit my_script.py as follows:

   from mech_client.interact import interact, ConfirmationType
   
   prompt_text = 'Will Gnosis pay reach 100k cards in 2024?'
   agent_id = 6
   tool_name = "prediction-online"
   chain_config = "gnosis"
   private_key_path="ethereum_private_key.txt"
   
   result = interact(
       prompt=prompt_text,
       agent_id=agent_id,
       tool=tool_name,
       chain_config=chain_config,
       confirmation_type=ConfirmationType.ON_CHAIN,
       private_key_path=private_key_path
   )
   print(result)

FAQ

On which chains are AI Mechs deployed?

The Mech repository contains the latest information on deployed Mechs.

Are AI Mechs deployed on testnets?

No. AI Mechs are currently deployed only on mainnets.

Where can I find the agent ID?

You can find the agent IDs for each chain on the Mech Hub or on the Mech repository.

How do I access an AI Mech on a different chain?

Use the --chain-config <name> parameter together with a valid <agent_id>, for example:

mechx interact "write a short poem" 2 --key ./ethereum_private_key.txt --tool openai-gpt-4 --chain-config celo --confirm on-chain
