Entitlement

Viewcast Maptiles is gated by the feature key viewcast.profiles.inventory_tiles, the same bundled entitlement that covers Viewcast inventory geometry (viewsheds, exposure paths, and gates).

• Grant required. Unlicensed organizations get 403 FEATURE_NOT_LICENSED when minting a grant. Contact sales for access.
• Metered billing rail required. The organization must be metered; credit-pack-only orgs get 403 TILE_GRANTS_REQUIRE_METERED.
• One entitlement, all layers. A single entitlement covers every published Viewcast layer (all five: viewsheds, both path layers, both gate layers) with no per-layer scoping.

Cost model

At the metered credit price of $0.05 per credit, tile delivery works out to $0.05 per 1000 tiles. Tile fetches accrue against your billing account under op id viewcast_tiles_fetch with a meter divisor of 1000. Empty tiles (a z/x/y coordinate with no features) return HTTP 204; responses may be gzip-encoded and clients must honor Content-Encoding.

A quick cost sanity model: a map session that pulls 60 tiles per view, serving 50,000 map views a month, fetches about 3,000,000 tiles, or 3,000 credits, or about $150.

Console visibility

Your organization admin can see the entitlement state and mint/revoke grants from the developer dashboard in the console. Grants minted through the API also appear there under the Viewcast Maptiles group in the console catalog; grant usage reporting (usage_30d) is a placeholder today and lands in a follow-up.
