issued.live is live
issued.live is open to the public today. This note is about how it is built and why it behaves the way it does, because those choices are the difference between a lookup you can rely on and one that quietly guesses.

issued.live went live today, allowing anyone to access the information it provides. The service was designed to publish what it observes and when it observes it, without reconciling that information against a registry or inferring data. Each record includes a last_update field, allowing users to judge the freshness of the data independently.
The index contains 334 million domains and ingested approximately 15.9 million certificates in the past 24 hours. The service updates the index tens of thousands of times per second, ensuring records reflect confirmed observations rather than lookups performed while the user waits. Every domain's DNS is re-scanned on a rolling cycle.
The data is served in three formats - JSON, Markdown, and Model Context Protocol - from a single URL. The service is free for basic lookups and offers additional features requiring a free key for reverse queries and newer domain registrations. The development team encourages reporting any inaccuracies in records to help improve the system. Documentation can be found at /developers. issued.live was built by Tuxxin.
