Lakekeeper
Lakekeeper is an open-source Apache Iceberg REST Catalog written in Rust and maintained by Vakamo. It manages Iceberg tables, views and namespaces for query engines such as Apache Spark, Trino, StarRocks, DuckDB, Athena, Flink and PyIceberg, vending short-lived, prefix-scoped storage credentials for S3, GCS, Azure ADLS and Microsoft OneLake/Fabric instead of handing long-lived keys to engines. It exposes three distinct HTTP APIs — the standard Iceberg REST Catalog API at /catalog/v1, a Lakekeeper-specific Management API at /management/v1 for bootstrapping, projects, warehouses, users, roles, tasks and fine-grained permissions, and a Data API at /lakekeeper/v1 that catalogs non-Iceberg generic tables such as Lance, Delta and Parquet. Authorization is pluggable (OpenFGA for RBAC/ ReBAC, Open Policy Agent bridge, Cedar in the commercial Lakekeeper+ distribution), authentication is OIDC/OAuth2 or Kubernetes service accounts, and change events are published as CloudEvents to Kafka or NATS. Lakekeeper is self-hosted software under Apache 2.0; commercial Lakekeeper+ and Lakekeeper Cloud are sold by Vakamo.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Lakekeeper the way a machine reads it — 19 machine-readable artifacts across 3 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Lakekeeper scores 53.9/100 (developing), with a separate agent-readiness read of 38/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Lakekeeper
Each block below is one kind of artifact we hold for Lakekeeper. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 13
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Lakekeeper Generic Table (Data) API
Lakekeeper's data-plane API served under /lakekeeper/v1, cataloging non-Iceberg table formats — Lance, Delta, CSV, Parquet — alongside Iceberg tables in the same Warehouse and N...

The authorization API from Lakekeeper — 1 operation(s) for authorization.
Lakekeeper Catalog API
The Catalog API API from Lakekeeper — 16 operation(s) for catalog api.

The Configuration API API from Lakekeeper — 1 operation(s) for configuration api.
Lakekeeper OAuth2 API

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Lakekeeper Rate Limits
RATE LIMITSEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Lakekeeper Events
ASYNCAPISecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Lakekeeper, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
