# Send Hackathon to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

### Aegis402 Shield Protocol (Hackathon/Testnet)

Blockchain security API for AI agents. Testnet version - pay with Base Sepolia USDC.

⚠️ This is the hackathon/testnet deployment. For production, use aegis-security.

### Skill Files

FileURLSKILL.md (this file)https://hackathon.aegis402.xyz/skill.mdpackage.json (metadata)https://hackathon.aegis402.xyz/skill.json

Base URL: https://hackathon.aegis402.xyz/v1

### Quick Start

npm install @x402/fetch @x402/evm

import { x402Client, wrapFetchWithPayment } from '@x402/fetch';
import { ExactEvmScheme } from '@x402/evm/exact/client';

const client = new x402Client()
  .register('eip155:*', new ExactEvmScheme(yourEvmWallet));

const fetch402 = wrapFetchWithPayment(fetch, client);

// Payments on Base Sepolia (testnet USDC)
const res = await fetch402('https://hackathon.aegis402.xyz/v1/check-token/0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?chain_id=1');
const data = await res.json();

### x402 Payment Flow (Testnet)

Agent calls any paid endpoint
Receives 402 Payment Required with Base Sepolia payment instructions
Pays testnet USDC on Base Sepolia (chain ID: 84532)
Retries request with payment proof header
Gets security scan result

Network: Base Sepolia (eip155:84532)
Currency: Testnet USDC

### Before Swapping Tokens

const tokenCheck = await fetch402(\`https://hackathon.aegis402.xyz/v1/check-token/${tokenAddress}?chain_id=8453\`);
const { isHoneypot, trustScore } = await tokenCheck.json();

if (isHoneypot || trustScore < 50) {
  console.log('⚠️ Risky token detected!');
}

### Before Signing Transactions

const simulation = await fetch402('https://hackathon.aegis402.xyz/v1/simulate-tx', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ from, to, value, data, chain_id: 8453 })
});

const { isSafe, riskLevel, warnings } = await simulation.json();

if (!isSafe || riskLevel === 'CRITICAL') {
  console.log('🚨 Dangerous transaction!', warnings);
}
