Usage metering
Slab5 separates credit-metered managed work from included platform activity. This gives teams clear spend controls without charging for every normal API request.
What is metered
Credits apply to:
- an AgentGrid managed workflow run
- Standard managed AI model-call token windows
- Premium managed AI model-call token windows
- embedding input tokens used for managed retrieval
The public rate card is 1 credit per workflow run, 1 credit per Standard managed model-call 4,000-token window, 6 credits per Premium managed model-call 4,000-token window, and 1 credit per 32,000 embedded tokens. One credit equals $0.01 USD.
Included activity
The following activity is included within plan fair-use limits and remains visible in usage and audit history:
- REST API traffic
- MCP tool calls
- webhook deliveries
- business record operations
- storage and egress
- workspace safe summaries
- deterministic BI metric retrieval and SQL planning
- Data Agent job dispatch and deterministic review summaries
- vector collection create and archive operations
Document upserts that generate embeddings consume embedding credits. Search, collection, and retrieval activity remains visible in Usage → Intelligence usage with collection and app attribution where available.
Managed AI and embeddings
For a managed workflow, Slab5 creates a temporary credit reservation immediately before each model call. After a call, it records actual token usage and settles the corresponding workflow and AI credits. Trace-only workflow steps do not create a separate AI charge. If a call fails, or if the workflow pauses at a human approval gate, the unused reservation is released.
BYOK runs do not consume managed AI credits. Slab5 records BYOK token telemetry for operational visibility while the provider bills the workspace directly.
Embeddings are measured from input tokens. The same credit rate applies to managed retrieval across RAG in a box, semantic product features, and other Slab5 retrieval surfaces.
Fair-use limits
Free, Builder, Team, and Business / Agency plans include monthly limits for API requests, MCP tool calls, webhook deliveries, records, storage, and egress. At 80% of a limit Slab5 warns the workspace. At 100%, reads are throttled and writes are soft-blocked with a structured response. See Billing and usage for current limits.
Usage visibility
Workspace owners and admins can inspect:
- plan and credit balance
- expiring and purchased credit lots
- credit transactions and active or released reservations
- AgentGrid managed AI and BYOK telemetry
- embedding and intelligence usage by collection
- request IDs, run traces, and audit events
App attribution
When an app-associated API key is used, Slab5 attributes applicable usage and audit records to the registered app. Use the app filter in Usage and Audit Log to separate production integrations, internal tools, and developer-managed RAG collections. Activity without an app association remains visible as workspace activity, so account owners can reconcile the complete account total without losing attribution detail.
