## 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 blockrun-ai-ef93eeb9 -d '<json body>'
```

Example prompt: Terminate the BlockRun sandbox with ID sandbox-abc123 and release all its resources.

## When to prefer this

Use this endpoint when you have finished executing code in a BlockRun sandbox (created via /sandbox/create) and need to clean up resources to avoid unnecessary charges or resource leaks. Always call this after your sandbox workflow is complete.

## Known failure modes

- Invalid or unknown sandbox_id returns a 404 or error response
- Sandbox already terminated returns an error or idempotency confirmation
- Payment failure (402) if USDC balance is insufficient
- Network timeout if sandbox termination takes too long
- Unauthorized access if sandbox_id belongs to a different user

## How this service works
