Comet

Comet is Perplexity's AI-native browser built on Chromium (Blink), integrating Perplexity Search and an agentic assistant that can summarize pages, draft emails, and complete tasks. Launched July 9, 2025 on Windows and macOS, with Android (Nov 2025), iOS (Mar 2026), and visionOS support added later. Initially gated behind a paid Perplexity subscription, opened free to everyone in October 2025. This is a consumer browser product with no publicly documented REST API surface.

Comet is profiled on the APIs.io network. Tagged areas include Artificial Intelligence, Browser, Consumer, Agents, and Chromium.

Comet’s developer surface includes engineering blog, FAQ, support, pricing, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Other styles, a README pill and a shields.io endpoint are on the badge page.

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/comet-browser: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Raycast Store Extensions (first-party publishers + community-wrapped products)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
