# [Answers Hub](https://rebilder.com/docs/answers-hub)

> A merchant-approved Q&A directory served through the gateway: drafted from your own catalog and the real searches agents sent you, published only after you approve each entry.

## How it works

- Mine — questions are proposed from your own pages (fetched as the gateway markdown you already serve) and the real zero-result searches agents sent your store: demand with receipts, never guesses.
- Draft — answers are composed offline from your own content only. A validator rejects any draft containing a number that does not appear verbatim in its cited source excerpt.
- Approve — drafts land in Console → Answers Hub with their sources shown. Nothing publishes without your approval, ever.
- Serve — approved entries become ordinary gateway documents at /answers/<slug> plus a collection index and FAQ structured data. No LLM runs at request time.

> **Freshness** Every published answer carries provenance with a TTL. Past it, the gateway falls back to HTML rather than serving a stale claim.

## Where answers serve from

Managed Shopify stores serve approved answers automatically — approval publishes straight into the hosted gateway, live at your storefront URLs within seconds. Self-hosted sites pull the approved set once at build time with the export API below and wire it as ordinary document sources.

## The export API

Authenticate with the site API key from Console → Settings. Approved entries only — drafts never leave the review queue.

Fetch your approved answers

```
curl https://api.rebilder.com/v1/answers \
  -H "Authorization: Bearer $REBILDER_API_KEY"
```

The response carries the raw entries and ready-to-wire gateway shapes: a `collection` for `/answers` and one `document` per entry (with provenance), so a build step can drop them straight into your gateway config:

Response shape

```
{
  "domain": "shop.example.com",
  "contentSha256": "…",
  "answers": [{ "slug": "…", "question": "…", "answer": "…", "groundings": […] }],
  "collection": { "url": "https://shop.example.com/answers", "items": […] },
  "documents": [{ "path": "/answers/…", "source": { /* DocumentSource */ } }]
}
```

## Availability

The Answers Hub is a paid add-on on any Pro plan, per site — enable it from Console → Billing. Serving is never gated: approved answers keep serving until their TTL lapses even if the add-on is cancelled, and a self-hoster can hand-write the same document shapes for free.
