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

The Yutori catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Yutori’s developer surface includes documentation, API reference, getting-started guide, authentication, pricing, signup flow, engineering blog, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

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 the provider profile at artifacts.apis.io/yutori/apis.yml: open an issue on github.com/api-evangelist/yutori to ask a question or point us at an artifact you publish.
