Aklivity

Aklivity builds Zilla, a stateless, source-available multi-protocol gateway for event-driven applications and AI agents. Zilla translates HTTP, SSE, WebSocket, MQTT, gRPC and MCP Streamable HTTP to and from Apache Kafka and other backends, configured declaratively in a zilla.yaml or driven directly from an OpenAPI or AsyncAPI document, with no custom code, connectors or separate MQTT broker. The Zilla MCP Gateway compiles OpenAPI specs, Kafka topics, Kafka Connect and schema registries into governed MCP tool sets that agents call through one authenticated endpoint. The Zilla Console adds an API and data-product catalog, a self-service developer portal, governance, audit and RBAC. Aklivity is a software vendor rather than a service operator: every Zilla runs inside the customer's own infrastructure, so there is no hosted Aklivity API and no Aklivity-issued credential.

Aklivity is listed with 4 APIs on the APIs.io network, including Zilla Gateway, and 3 more. Tagged areas include AI Gateway, API Gateway, Agent Infrastructure, Apache Kafka, and AsyncAPI.

The Aklivity catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Aklivity’s developer surface includes documentation, getting-started guide, pricing, API reference, support, authentication, sandbox, and 35 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/.

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/aklivity: 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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Streaming (Apache Kafka protocol)	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.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

    to those backends. A listing cache answers tools/list, prompts/list and resources/list before any upstream is reached,
    and an OAuth guard carries per-user identity through to the call. Aklivity hosts no MCP endpoint of its own — the gateway
    is deployed and owned by the operator.'
