About Manifest by omfang

Manifest turns any URL into a structured map of what an AI agent can actually do on that page — every button, form and input, described with the fields it needs, the input types, what is required, and what must happen before it can move on. The gap it addresses is precise: give an agent a browser and it can see a page; give it a scraper and it can read one; neither tells it what it is allowed to do there. Today agents either screenshot and guess, or a developer hand-writes CSS selectors that break the next time the page ships a redesign. Manifest's approach is to visit the URL and read its accessibility tree the way a screen reader would, then cross-reference that against the actual DOM for the details accessibility trees miss — required fields, input types, placeholders, disabled states. The combined picture is emitted as a clean JSON action manifest describing every interactive element in terms an agent can reason about and act on, which is a far more durable contract than a selector list because it survives markup changes that preserve semantics. It is delivered as an API with a key, documented endpoints and a live try-it surface, positioning itself as an action layer for agents rather than another scraping product.
