Use this request as a starting template:
We operate [legal entity and domains] and are evaluating non-wagering slot demos for [presentation and intended audience]. Please confirm whether you support this publisher use case and provide the applicable agreement, evidence of authority to supply, studio/title territorial restrictions, and permissions for the proposed domains, assets and promotional presentation. Please also provide an export covering our attached priority titles, current integration documentation, chargeable-event definitions, support and withdrawal terms, and permission for a controlled pilot in the listed environments. Please mark unanswered points explicitly rather than treating them as included.
The immediate action: assign one owner, complete the brief, send the same evidence request to suitable candidates and reserve production integration spending until the rights gate is resolved.
