Bubble
Bubble is a no-code application development platform that lets builders ship full-stack web and mobile apps without writing code. Bubble exposes three developer APIs — the Data API for CRUD against the app database, the Workflow API for triggering backend automations, and a JavaScript Plugin API for extending the platform with custom actions and elements. Server-side consumption is metered in Workload Units (WU) bundled into a tiered subscription (Free, Starter, Growth, Team, Enterprise) with overage pricing for additional WU and storage.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Bubble the way a machine reads it — 71 machine-readable artifacts across 6 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 — Bubble scores 80.3/100 (exemplar), with a separate agent-readiness read of 55/100 (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 Bubble
Each block below is one kind of artifact we hold for Bubble. 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 6
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.
Bubble Data API
REST API exposing the Bubble app database. Supports search with constraints, cursor-based pagination, single-record CRUD, bulk create (up to 1,000 records), and metadata discove...
Bubble Workflow API
REST API for triggering backend workflows defined in the Bubble editor. Each workflow is exposed at `/api/1.1/wf/{workflow_name}` and can be configured for POST or GET, with aut...
Bubble Action API
Server-side and client-side action functions invoked by Bubble workflows.
Bubble Context API
Helpers exposed on the runtime context object.
Bubble Element API
Visual element lifecycle hooks invoked by the Bubble page renderer.
Bubble Thing API
Database object accessors exposed to plugin code.
Postman Collections 3
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.
Ready-to-run Postman collections for exercising this provider's APIs.
Open Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).
Arazzo Workflows 10
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
Bubble Bulk Create Then Search
Bulk create many records of a data type, then search the type to verify they landed.
ARAZZOBubble Create and Verify a Thing
Create a single record of a data type and read it back to confirm it persisted.
ARAZZOBubble Create a Thing Then Trigger a Backend Workflow
Create a record via the Data API, then trigger a backend workflow that processes it.
ARAZZOBubble Discover Data Types Then Search
Read the Data API metadata to discover exposed types, then search one of them.
ARAZZOBubble Get Then Replace a Thing
Read a record by id to confirm it exists, then fully replace it with a new object.
ARAZZOBubble Initialize Then Trigger a Backend Workflow
Run the one-time detection call for a backend workflow, then trigger it with the same parameters.
ARAZZOBubble Search Then Delete a Thing
Search a data type for a record matching a constraint and delete the first match.
ARAZZOBubble Search Then Update a Thing
Search a data type for a record matching a constraint and modify the first match.
ARAZZOBubble Trigger a Workflow Then Log a Thing
Trigger a backend workflow and record its result by creating a record via the Data API.
ARAZZOBubble Upsert a Thing
Find a record by a key field and update it if it exists, otherwise create it.

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.
Bubble 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.

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.

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.

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.
