Registration

Agent registration in the almanac-contract is a key part for remote agents communication.

To be found by other μAgents, each μAgent needs to register (paying a small fee) in the almanac contract using their agent address. Therefore, your agents need to have funds available in their Fetch address. When using the testnet, you can use the function fund_agent_if_low to fund your agent:

from uagents.setup import fund_agent_if_low

agent = Agent(name="alice", seed="agent1 secret phrase")

fund_agent_if_low(agent.wallet.address())

This function will check if you have enough tokens to register in the almanac-contract. If not it will add tokens to your Fetch address. Make sure to add a seed to your agent so you don't have to fund different addresses each time you run your agent.

μAgents can communicate by querying the almanac-contract and retrieving an HTTP endpoint from the recipient μAgent. Therefore, we need to specify the service endpoints when defining an agent:

agent = Agent(
    name="alice",
    port=8000,
    seed="agent1 secret phrase",
    endpoint=["http://127.0.0.1:8000/submit"],
)

Here we defined a local http address, but you could also define a remote address to allow agent communication over different machines through the internet.
