Lucid
Lucid Software Inc. is the visual collaboration company behind the Lucid Suite — Lucidchart (intelligent diagramming), Lucidspark (virtual whiteboarding) and Lucidscale (cloud visualization) — plus the Lucid Cloud, Process and Enterprise Shield accelerators and airfocus. The Lucid Developer Platform at developer.lucid.co publishes three OpenAPI-described surfaces: the Lucid REST API on api.lucid.co for documents, folders, sharing, embeds, comments, teams, repositories, legal holds, licenses and audit logs; the Lucid Data API on data.lucid.app for the structured data sets, collections, schemas and data items that back data-linked diagrams; and a SCIM 2.0 API on users.lucid.app for enterprise user and group provisioning. Lucid also ships an in-editor Extension API (lucid-extension-sdk plus the lucid-package CLI), an Embed SDK, and an OAuth-gated remote MCP server at mcp.lucid.app that lets AI clients search, read, edit and create Lucid documents. Lucid is privately held and trades on secondary markets.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Lucid the way a machine reads it — 16 machine-readable artifacts across 5 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 — Lucid scores 62.7/100 (strong), with a separate agent-readiness read of 49/100 (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 Lucid
Each block below is one kind of artifact we hold for Lucid. 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 5
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.
Lucid REST API
The Lucid REST API provides programmatic access to manage documents, users, folders, sharing, licensing, and audit logs across the Lucid Suite (Lucidchart, Lucidspark, and Lucid...
Lucid Data API
The Lucid Data API enables external applications to create, read, update, and delete structured data linked to Lucid documents. 50 operations across data sets, data set grants a...
Lucid SCIM API
The Lucid SCIM 2.0 API enables identity providers to automatically provision and deprovision users and groups in a Lucid account. 15 operations over /Users, /Groups, /Schemas an...
Lucid MCP Server
Lucid's remote Model Context Protocol server. Connects AI clients (ChatGPT, Claude, Microsoft Copilot, Cursor) to Lucid documents so they can be searched, retrieved, edited, sum...
Lucid ChatGPT Plugin API
The API behind Lucid's ChatGPT plugin — accepts Mermaid diagram source and returns a rendered image link plus, for flowcharts, an editable Lucidchart link. Described by the Open...
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).
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERRate 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.
Lucid Rate Limits
RATE LIMITSSecurity Posture 4
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.

SECURITYScopes 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.
OAuth scopes governing access to this provider's APIs.
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 Lucid, 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.
