Human guide: work with your agent → Inspect one Versium action before starting provider-backed work. Your first result is a verified input and output contract.

​
Provider-specific requirements

Use Versium for US consumer and business enrichment. If the workspace connects its own API key, that key takes precedence and Deepline does not bill the provider usage. Otherwise, actions with complete match-credit pricing use Deepline-managed access. Contact Append and Predictive Scores still require a workspace key because the supplied pricing table does not fully price them. Choose the narrowest action and output set that answers the request. Contact, demographic, audience, and predictive-score actions require at least one person identifier. Firmographic append requires a company identifier. Treat hashed email input as sensitive data even though it is not plaintext.

​
Find an applicable action

Confirm your effective workspace, then search the live catalog:
Search returns candidates. Check the returned provider and operation rather than selecting a similar title automatically.

​
Inspect the selected contract

Replace <returned-tool-id> with the identifier returned by discovery:
These commands do not execute the selected provider action. Read its required inputs, supported access mode, pricing unit, outputs, and limits. A connection does not establish that every action supports BYOK. Follow the provider-specific requirements above and the live action contract.

​
Prepare one reviewed input

Use one authorized record that matches the inspected schema. Preserve its source identity and define the result you will accept. Open the action reference for its payload and response shape. Provider-backed execution can incur usage or external effects. For reusable logic, follow Write Plays. For direct-call recovery, use Tool execution recovery.
Continue only when the workspace, provider, required fields, acceptance rule, and applicable price are understood. Keep unavailable access separate from no-result evidence.
