New

We've added `POST /v3/domains/check-availability` to the Domains API, so you can check the availability and indicative pricing of up to 25 domains in a single request instead of making one call per domain.

## What changed

A new endpoint is available:

* `POST /v3/domains/check-availability` — accepts a JSON body with a `domains` array (1–25 names) and returns one [`Availability`](https://developer.godaddy.com/docs/references/rest/domains/v3/discovery#check-availability-of-a-single-domain) result per domain in request order inside `{ "items": [...] }`. Domains that cannot be checked carry an `error` object on that item rather than failing the whole request.

One optional request field gives you control over the check behavior:

* `optimizeFor` — `SPEED` (default) uses cached zone data for a fast response; `ACCURACY` performs a live registry check for authoritative availability at higher latency.

Availability results are best-effort and indicative. The authoritative availability check always runs at quote time (`POST /v3/domains/registration-quotes`).

For single-domain checks without a request body, the existing `GET /v3/domains/check-availability` endpoint is unchanged.

## Who is affected

Any developer building domain search or catalog experiences on the Domains API. The `domains.domain:read` OAuth scope is required — no new scope is needed if you already call the GET endpoint.

Existing integrations using `GET /v3/domains/check-availability` are unaffected.
