# Choose a maintained lookup

## 1. Have your context ready

Have the identifiers you know and decide whether you need a work email, personal email, phone, profile, company record, or contacts at an account.

## 2. Ask your agent

Paste this into your agent, then provide your task and example inputs when it asks:

```deepline-prompt theme={null}
/deepline-gtm Help me choose a maintained Deepline lookup. Compare my available identifiers with the current Play contracts. Explain which route fits, what it can return, and which results would remain unresolved. Prefer one known record for the first approved lookup. If the task needs branching, a trigger, or an external write, explain whether we need a custom Play instead.
```

Complete any requested sign-in yourself. Give the agent the missing information before approving execution. Provider-backed work can incur usage.

## 3. Review the result

The chosen lookup accepts your actual input. One successful lookup is a reason to review a representative file pilot, not evidence of universal coverage.

Ask your agent:

```deepline-prompt theme={null}
/deepline-gtm Compare the result with the acceptance rule we agreed. Show the evidence for accepted and rejected outcomes, unresolved questions, and recorded Deepline usage where work ran. If work is still running or a response is uncertain, inspect the original saved execution before proposing another request. Explain the next decision I need to make.
```

Approve a larger job, recurring work, or external changes only after reviewing that decision.

## Check your understanding

Can a LinkedIn-only input always substitute for a name-and-domain contract?

> No. Choose the contract matching the available identifiers, or obtain the
> missing evidence explicitly.
