Kurrent

Kurrent — formerly Event Store Ltd — builds KurrentDB, an event-native database purpose-built to store, process and deliver application state changes as an immutable, append-only log of events. Where a traditional CRUD database overwrites rows and discards the history that produced them, KurrentDB retains every state change as a first-class event, giving applications a complete audit trail, temporal queries and the ability to replay history to rebuild state or seed new read models. The product line spans KurrentDB (open-source and commercial, self-hosted), Kurrent Cloud (managed clusters on AWS, Azure and Google Cloud), Kurrent Enterprise, and Capacitor, a shared memory layer for agentic coding. Developers integrate over a primary gRPC protocol with official client SDKs for .NET, Java, Node.js, Python, Go and Rust, or over the native AtomPub-style HTTP API. Connectors move events in and out of Kafka, MongoDB, Elasticsearch, RabbitMQ, Pulsar, SQL and HTTP endpoints. KurrentDB is widely used for event sourcing, CQRS, event-driven microservices, change data capture and, increasingly, as durable memory for AI agents.

Kurrent publishes 9 API contracts indexed on the APIs.io network, including Admin API, Gossip API, Info API, and 6 more. Tagged areas include Company, Database, Event Sourcing, Event Streaming, and Event-Driven Architecture.

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

Kurrent’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 42 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):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

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	41.4	-	1
Red Hat Certified Ecosystem (certified partner containers + certified OpenShift operators)	builds-on	41.4	-	1
Flathub Linux App Publishers (company-published, domain-verified Linux desktop apps)	builds-on	41.4	-	1
Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers)	builds-on	41.4	-	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.
