## 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 api-agentinternetruntime-com-2079ddeb
```

Example prompt: What SDK capabilities does the Agent Internet Runtime support for github.com? Include execution details with selectors and macros so I can see which ones have desktop macro support.

## When to prefer this

Use this endpoint when an AI agent needs to discover what SDK capabilities and automation actions are available for a specific web domain at runtime, especially when planning browser automation or agentic workflows that require knowledge of available macros and selectors for that domain.

## Known failure modes

- Payment required (402) if no valid x402 payment or session ticket is provided
- Unknown or unsupported domain returns empty capabilities array
- Invalid 'include' enum value returns validation error
- Network timeout or service unavailability returns 5xx error

## How this service works

SDK capabilities query ($0.01/request direct, or $0.003/request via Session Ticket at /v1/billing/tickets)

## Output

A JSON object with a success flag and a data object containing the queried domain and an array of capability objects, each with a name, confidence score, description, and a boolean indicating whether a desktop macro is available.
