List the agent cost catalog
What the workspace’s AI usage is priced against: the global registry row in force right now for each (provider, model) merged with the workspace’s own negotiated override, then the workspace’s custom cost items (source: "custom", custom_item_id set), then the (provider, model) pairs this workspace’s telemetry has carried that nothing prices (source: "unlisted"). An unlisted row is unpriced — its rates are zero because there is no catalog entry, never because the vendor is free — so never render it as $0; price it by creating a custom cost item for the same pair and traffic from then on is priced. Token rates are USD per million tokens, dimensions holds the extra cost dimensions, and every rate is a decimal string. Each row also carries whether the model is in the workspace’s catalog (enabled) and why (enablement_source): seen when the workspace has actually called it, manual when somebody answered for it explicitly, default_off for a registry model never touched. Pass enabled_only=true for just the catalog; the default is the whole registry.
