## 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 citationcheck-hg-subscription-status-610b2383
```

Example prompt: Check my current CitationCheck HG subscription — I want to know which plan I'm on, how many citation-audit queries I have included, whether it auto-renews, and how long the plan lasts.

## When to prefer this

Use this endpoint when an agent needs to check the remaining quota or plan details before invoking a citation audit batch, or when deciding whether a subscription renewal is needed. Prefer this over the audit endpoints when the goal is account/plan introspection rather than actually auditing references.

## Known failure modes

- 401/402 Unauthorized – missing or invalid payment/auth credentials
- No active subscription found – account has no current plan
- Network timeout reaching chatgpt.site subdomain
- Empty or malformed JSON response if subscription data is unavailable
