A prebuilt Play is a Deepline-maintained operation with a defined input,
result rule, and run record. Use one for a bounded lookup, such as a work email,
LinkedIn profile, mobile phone number, company profile, or set of contacts at an
account. Use a custom Play when the job needs your own
code, a trigger, several steps, approval logic, or an external write.
Choose a starting Play
If you do not know the exact Play name, search the live catalog:
Validate the contract first
Read the Play’s input and output contract, then validate that it is available:
This validation does not deploy the Play, start a run, or spend Deepline
credits.
Run one representative lookup
Use a real row whose answer you can review:
The run can call paid providers. Review the returned value, any no-result
reason, and the Deepline-credit usage before you use the Play on a file.
A prebuilt Play can return no result. Having the expected fields does not
guarantee coverage or delivery.
Move to a file only after the lookup is right
For a CSV, use the matching batch Play and a separate pilot file. The email
waterfall guide shows the complete sequence, including
safe contract validation, a representative pilot, and export.
Next step
When one lookup is not enough, write a custom Play that
keeps your transformation, approval, and destination logic in one reviewed
workflow.
