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).
