# Quick Start

To get started, try simulating a transaction without setting an API key.

```bash
curl -XPOST https://trykoi.com/api/v1/optimism/tx/simulate -H 'Content: application/json' -d '{
  "tx": {
    "from":"0x9eef87f4c08d8934cb2a3309df4dec5635338115",
    "to":"0x76FB31fb4af56892A25e32cFC43De717950c9278",
    "data":"0x095ea7b300000000000000000000000068b3465833fb72a70ecdf485e0e4c7bd8665fc45ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"
  }
}' | jq .
```

You should get a response like...
