Apache CouchDB

Apache CouchDB is an open-source distributed document-oriented NoSQL database governed by the Apache Software Foundation. It uses JSON for data storage, a RESTful HTTP/JSON API for all database operations, and the Couch Replication Protocol for multi-primary synchronization across servers, mobile devices, and browsers. CouchDB supports Mango queries, MapReduce views, and offline-first application architectures.

agent ready

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Apache CouchDB the way a machine reads it — 113 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 — Apache CouchDB scores 62.2/100 (strong), with a separate agent-readiness read of 54/100 (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.

How we profile Apache CouchDB

Each block below is one kind of artifact we hold for Apache CouchDB. 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.

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.

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.

FinOps 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.

Features 8

The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.

Notable capabilities this provider offers.

RESTful HTTP/JSON API

All database operations are performed via a clean HTTP API using JSON, making it accessible from any HTTP-capable client.

Multi-Primary Replication

The Couch Replication Protocol enables seamless bidirectional synchronization across servers, mobile, and browser environments.

Offline-First Architecture

Applications can operate fully offline and sync changes when connectivity is restored, enabled by conflict-aware replication.

Mango Query Language

Declarative JSON-based query language for ad-hoc document queries with index support, similar to MongoDB query syntax.

MapReduce Views

Persistent, incrementally updated secondary indexes defined via JavaScript MapReduce functions stored as design documents.

Changes Feed

Real-time notification feed of all database changes, supporting long-polling, continuous, and event-source modes.

Cluster Support

Built-in clustering with consistent hashing for horizontal scaling and high availability across multiple nodes.

MVCC and ACID

Multi-Version Concurrency Control ensures non-blocking reads; document updates are ACID-compliant at the document level.

Event 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.

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.

Examples 24

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 3

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.
