Europe & regional availability
Developer-service country conditions checked separately from the personal Muse agent.
Reviewed scope: Muse Code and Meta model access
Reviewed on:
Depends on access and configuration
Geographic Use Policy and account access
The 12 October policy does not list the EU/EEA, United Kingdom or Switzerland as blanket-restricted territories. Access still applies only where Meta has enabled it. The policy alone therefore does not confirm purchasing availability for a specific account.
Region, reason and source
Region covered: EU/EEA, United Kingdom and Switzerland: check account access
Documented reason: Meta sets geographic access and trade restrictions. An AI Act or DMA-based exclusion of these regions is not established here.
