Give your AI agent a wallet in under 5 mins with Aethergent

Building an autonomous agent is one thing; giving it the ability to pay for its own API credits or interact with on-chain protocols is another. Traditionally, this required complex SDKs and API keys.

With Aethergent, you can bypass the onboarding friction and give your agent a wallet with a single HTTP call.

1. The Basics: Crypto, Wallets, and Keypairs

Before we code, let's break down what your agent actually needs to interact with a blockchain like Ethereum:

What is a "Wallet"? In the context of an AI agent, a wallet isn't an app or a physical object. It is a digital identity that allows the agent to sign transactions and hold assets.
The Keypair: Every wallet consists of two mathematically linked strings of characters:
- Private Key: A secret 256-bit number that acts like a digital signature. If your agent has this key, it can move funds. Never share this.
- Public Address: Derived from the public key, this is the "account number" (e.g., 0x742...) that others use to send funds to your agent.
Ethereum/EVM: Ethereum is the network, and the EVM (Ethereum Virtual Machine) is the standard it uses. A wallet generated via Aethergent works across all EVM-compatible chains, including Base, Optimism, Arbitrum, and Polygon.

2. How Aethergent Works

Aethergent is an open API that performs the math required to generate these keys and returns them instantly over HTTPS. It is stateless and zero-auth, meaning no signups or API keys are required.

⚠️ Security Note: Aethergent does not log or store private keys. However, because the key is generated on a server, it is best suited for micropayment wallets and agent operations rather than storing large amounts of capital.

3. Step-by-Step Integration

Step A: Generate the Wallet

Your agent simply needs to make a POST request to the Aethergent root URL.

Using CURL

curl -X POST https://aethergent.com/

Using Python

import requests

# One call to get a fresh Ethereum keypair
response = requests.post("https://aethergent.com/")
wallet = response.json()

print(f"Address: {wallet['address']}")
print(f"Private Key: {wallet['private_key']}")

Using Node.js

const res = await fetch("https://aethergent.com/", { method: "POST" });
const wallet = await res.json();

console.log(`Agent Address: ${wallet.address}`);

Step B: Fund the Agent

Once you have the address, send a small amount of ETH or USDC to it from your own wallet.

Step C: Secure the Key

Do not hardcode the private key. For agents, we recommend:

Environment Variables: Best for Docker or Cloud deployments.
Secret Managers: Use AWS Secrets Manager, GitHub Secrets, or equivalent to keep the key encrypted at rest.
Ephemeral Use: Generate a new wallet for every session if the task is one-off.

4. Advanced: Model Context Protocol (MCP)

If you are using frameworks like Claude Code or Cursor, Aethergent supports MCP.

Your agent can natively discover the generate_wallet tool via a JSON-RPC 2.0 call to /mcp, allowing it to create its own wallet without you writing any custom HTTP logic.

Your agent is now ready to transact on the open web!
