Cloud API

One POST, one piece of evidence

Get an API key

One POST to /search. Every hit carries evidence your agent can verify and cite: what was found, where, and at which second.

One line of work, three steps

Search & Cite works today. Visual memory and embodied footage are on the roadmap, delivered in the same evidence structure.

01Available now

Search & Cite

Ask in plain words and get the moment it happened — with the quote, the source, and a timestamp you or your agent can verify.

02On the roadmap

Scene Understanding

Visual memory reads what is on screen — places, objects, and actions — so a query can land on a scene even when nobody said the words.

03On the roadmap

Ego & Embodied

Head-mounted and robot-captured footage is long, repetitive, and mostly unlabeled. Cerul is built to pin down the moment a hand, a tool, or a task actually changed state.
