Kernel

Kernel is browser infrastructure for AI agents and automations. It runs sandboxed cloud Chromium browsers that spin up in under 30ms, with Playwright execution, computer-use controls, managed authentication into third-party sites, reusable browser profiles, proxies, pre-warmed browser pools, session replays, live telemetry, and a serverless App platform for deploying and invoking agent actions. Kernel exposes a REST API (OpenAPI 3.1, 135 operations across 22 tags), first-party TypeScript, Python and Go SDKs, a CLI, and a centrally hosted MCP server so agents can drive real browsers. Backed by General Catalyst.

Kernel publishes 28 API contracts indexed on the APIs.io network, including API Keys API, Apps API, Audit Logs API, and 25 more. Tagged areas include Company, Browser Automation, Web Agents, Browser Infrastructure, and AI Agents.

Kernel’s developer surface includes authentication, CLI, changelog, documentation, API reference, getting-started guide, support, and 28 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/.

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
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)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 more unmet checks in the Agent Readiness table above.

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	builds-on	42.5	-	1
Stripe App Marketplace and Partner Ecosystem (builders on Stripe)	builds-on	42.5	-	1
Jamstack Hosting Integrations (Vercel Marketplace and Netlify Integrations publishers)	builds-on	42.5	-	1

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.
