Yutori

Yutori builds AI web agents delivered as an API. Its Navigator (n1.5) computer-use model drives cloud browsers to navigate, click, type, and extract structured data, and is OpenAI Chat Completions compatible. Scouts are always-on agents that monitor the web and alert on changes; the Research API runs one-time multi-source web research; and a hosted MCP server exposes the same capabilities over the Model Context Protocol. Founded in 2024 by former Meta AI researchers and backed by Radical Ventures and Felicis, Yutori is strongly agent-native: API-key bearer auth, published llms.txt, agent Skills, an RFC 9727 API catalog, and OAuth resource metadata. Pay-as-you-go pricing with $5 in free credits.

Yutori publishes 5 APIs on the APIs.io network, including Browsing API, Chat Completions API, Health API, and 2 more. Tagged areas include Company, Artificial Intelligence, Agents, Web Automation, and Browser Automation.

The Yutori catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Yutori’s developer surface includes documentation, API reference, getting-started guide, authentication, pricing, signup flow, engineering blog, and 22 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/yutori: open an issue to ask a question, or submit a pull request to add artifacts.
