## 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-record-manager-448c-net-4715a4be -d '<json body>'
```

Example prompt: Create a DNS record for the subdomain 'my-agent' under 448c.net pointing to my server — no account needed, just pay with USDC.

## When to prefer this

Choose this endpoint when you need to quickly provision a DNS subdomain under 448c.net without creating an account or obtaining an API key — ideal for ephemeral agent deployments, demos, or sandboxes that require a public hostname on demand, paid with USDC via x402.

## Known failure modes

- Invalid label format (must match ^[a-z0-9][a-z0-9-]{1,30}$) returns a validation error
- Reserved label names are rejected
- Malformed or empty records array causes a schema validation failure
- Payment failure or insufficient USDC balance results in HTTP 402 with no state change
- Duplicate label conflicts may cause errors if the subdomain is already taken

## 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

Returns confirmation of the created or updated DNS records for the requested subdomain label under 448c.net, including the fully qualified hostname and the records that were set.
