Before a lien-deadline API pilot goes to legal, check these four things

Most API pilots in construction finance stall in the same meeting. Engineering has a working demo, then someone from legal asks what happens when the API returns a date for a state you don't actually cover, and nobody has an answer written down.

A short list helps here. It's less about features and more about whether the people signing off can explain what the output means.

Business fit. Does it calculate deadlines for the states your jobs are in? Does the output land in the ticket or task system you already use, and does it arrive fast enough for your closeout cadence?

Exceptions. What does an unsupported state look like in the response? If a calculated date is already in the past, or negative, does something visible happen, or does it sit in a field nobody reads? During a pilot, even a small manual-review path should be documented.

People can read the results. Can someone in leadership say the difference between a notice deadline and a lien deadline? Do finance and operations know who acts on each alert? Does legal have the state context behind a date, not just the date?

Technical readiness. The same payload shape should work in test and in staging. One or two integrations should run end to end before anyone signs. Security will ask about key rotation, scope limits and monitoring, so have those answers ready.

If you can tick every line, the meeting tends to move from comparing feature lists to asking whether the team trusts the output.

LienDeadline keeps this as a 30-second buying checklist for API evaluation in its help center, with a sandbox for testing payloads against contractor and owner scenarios.
