Unity Catalog
Unity Catalog provides an industry‑first universal catalog for data and AI, enabling organizations to manage, discover, and govern data assets across multiple formats, engines, and environments. The platform offers multimodal interfaces, extensive integrations with tools like Spark, DuckDB, and LangChain, and supports AI workloads through dedicated APIs. It includes features for tables, functions, models, and user privileges, along with robust security and governance capabilities.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Unity Catalog the way a machine reads it — 24 machine-readable artifacts across 1 API, 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 — Unity Catalog scores 31.0/100 (thin), with a separate agent-readiness read of 21/100 (agent aware). 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 Unity Catalog
Each block below is one kind of artifact we hold for Unity Catalog. 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.
Unity Catalog Catalogs API
A catalog is the first layer of Unity Catalog’s three-level namespace. It’s used to organize your data assets.
Unity Catalog Credentials API
The Credentials API from Unity Catalog — 2 operation(s) for credentials.
Unity Catalog Delta Commits API
"Delta commits" is a Delta tables feature that allows Delta tables to designate a coordinator to coordinate commits. This is Unity Catalog's API to allow Unity Catalog be the co...
Unity Catalog External Locations API
The External Locations API from Unity Catalog — 2 operation(s) for external locations.
Unity Catalog Functions API
Functions implement User-Defined Functions (UDFs) in Unity Catalog. The function implementation can be a SQL expression/query or a python function, and it can be invoked whereve...
Unity Catalog Grants API
The Grants API from Unity Catalog — 1 operation(s) for grants.
Unity Catalog Metastores API
A metastore is the top-level container of objects in Unity Catalog that stores all UC assets.
Unity Catalog Schemas API
A schema (also called a database) is the second layer of Unity Catalog’s three-level namespace. A schema organizes tables, volumes and functions.
Unity Catalog Tables API
A table resides in the third layer of Unity Catalog’s three-level namespace. It contains rows of data. A table can be managed or external.
Unity Catalog Temporary Credentials API
Temporary credentials are used to access storage locations or assets for a limited lifetime.
Unity Catalog Volumes API
Volumes are a Unity Catalog capability for accessing, storing, governing, organizing and processing files. Use cases include running machine learning on unstructured data such a...
Unity Catalog Model Versions API
Model versions contain all artifact files associated with an individual machine learning model. They are associated with a single parent model and have an integer identifier, in...
Unity Catalog Registered Models API
Registered models are machine learning models that are stored within the Unity Catalog model registry. They are comprised of all versions of a single model that a user wishes to...

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON-LDSpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

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.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Unity Catalog, 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.
