Java
Java is a high-level, class-based, object-oriented programming language developed by Sun Microsystems and now stewarded by Oracle. The Java Standard Edition (SE) platform provides a comprehensive set of APIs and class libraries for building cross-platform applications. Key APIs include Collections, Concurrency, I/O, NIO, Networking, JDBC, Reflection, and Streams. Java is the foundation for the Jakarta EE enterprise platform and is supported by an extensive ecosystem of open source projects, frameworks, and runtimes.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Java the way a machine reads it — 13 machine-readable artifacts across 9 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 — Java scores 28.3/100 (emerging), with a separate agent-readiness read of 7/100 (human only). 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.

How we profile Java
Each block below is one kind of artifact we hold for Java. 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 9
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.
Java Core API
Core Java SE API including fundamental classes and utilities for building Java applications, including the java.lang, java.util, java.io, and other foundational packages.
Java Collections Framework
Interfaces and classes for storing and manipulating groups of objects including List, Set, Map, and Queue implementations.
Java I/O API
Input and output through data streams, serialization and the file system using the java.io package.
Java NIO API
Non-blocking I/O operations for buffers, channels, selectors, and asynchronous file system access.
Java Networking API
APIs for networking applications including HTTP, sockets, and URLs.
Java Concurrency API
Utilities for concurrent programming including executors, thread pools, locks, atomic variables, and concurrent collections.
Java Database Connectivity (JDBC)
API for connecting to relational databases and executing SQL queries from Java applications.
Java Reflection API
Examine and modify the runtime behavior of applications by inspecting classes, methods, fields, and annotations.
Java Stream API
Functional-style operations on streams of elements including map, filter, reduce, and collect operations.

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 six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Java Plans Pricing
PLANSRate 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.
Java Rate Limits
RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.

FINOPSSecurity Posture 1
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.
