Use this endpoint to verify the relayer is operational and supports the mint you want to burn. The mints field is the authoritative runtime source of truth — the SDK’s hardcoded mint list is a fallback only. The SDK calls this internally via getUmbraRelayer() to cache the relayer’s fee payer address.
