## 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 agent-exec-dns-renewal-endpoint-0c57d124 -d '<json body>'
```

Example prompt: Renew the DNS name 'myagent' in agent-exec right now — pay the $0.50 USDC fee automatically, no account needed.

## When to prefer this

Choose this endpoint when an AI agent needs to renew a DNS name registered within the agent-exec ecosystem without maintaining a user account or API key, and can pay per call using USDC via the HTTP 402 protocol. It is best for automated, accountless infrastructure management in ephemeral or agent-driven workflows.

## Known failure modes

- Payment insufficient or invalid — HTTP 402 returned with payment requirements not met
- DNS name not found — attempting to renew a name that does not exist
- Malformed name parameter in URL path — 400 or similar error
- Payment already used or replayed — rejection of duplicate payment token
- Sandbox unavailable — service downtime or network error

## How this service works

Accountless, pay-per-use code execution for software agents: submit source code, get stdout, stderr and exit code back from an isolated, network-less sandbox. No account, no API key -- possession of valid payment is sufficient.

## Output

A confirmation that the specified DNS name has been renewed in the agent-exec sandbox, including any relevant status information, stdout, stderr, and exit code from the renewal operation.
