## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability automaton-sovereign-firewall-transaction-simulator-197e9a08
```

Example prompt: Can you simulate a GET request through the Automaton-Sovereign firewall to see whether it would be allowed or blocked before I actually send it?

## When to prefer this

Choose this endpoint when you need to dry-run or pre-validate an HTTP GET transaction against a firewall rule engine before executing it live, especially within the Automaton-Sovereign infrastructure. Useful for debugging blocked requests or testing new query parameter combinations against firewall policy without risking live traffic disruption.

## Known failure modes

- Missing required 'type' field (must be 'http') returns validation error
- Missing required 'method' field returns validation error
- Invalid method value (non-GET) returns schema mismatch error
- Malformed query parameters may cause unexpected simulation results
- Payment not provided or insufficient USDC results in 402 Payment Required

## How this service works

Automaton-Sovereign Value API call

## Output

Returns a simulated firewall decision for the provided HTTP GET transaction, including whether the request would be allowed or blocked, and likely the firewall rule or reason behind the decision.
