## What changed

We've added `POST /v1/customers/{customerId}/aftermarket/listings/available` so you can check whether 1–50 domains have active aftermarket auction listings and get an `AVAILABLE` or `UNAVAILABLE` result per domain.

Optional `?includes=listingMin`, `?includes=listing`, or `?includes=enrichment` attach listing details and domain signals (GoDaddy, Estibot, SEMrush, Majestic) for `AVAILABLE` domains, so you can verify targets before bidding or purchase. Existing integrations are unaffected; this endpoint is additive.

You can use the `MY` alias for `{customerId}`. Authenticate with a legacy API key (`sso-key`).
