API Evangelist
The index of everything available via the API Evangelist developer portal at developer.apievangelist.com — sixteen years of API research served as one REST API, an MCP server for agents, and the static JSON feeds behind each network collection.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles API Evangelist the way a machine reads it — 29 machine-readable artifacts across 20 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 — API Evangelist scores 64.1/100 (strong), with a separate agent-readiness read of 53/100 (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 API Evangelist
Each block below is one kind of artifact we hold for API Evangelist. 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 20
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.
API Evangelist Network API
The whole network behind one REST API — unified search, 5,100+ posts, 77 topic areas, 2,400+ governance building blocks, conversations, papers, services, vocabulary, and newslet...
API Evangelist Governance & Discovery API
Governance and discovery compute over the API Evangelist rule catalog — lint an OpenAPI against 461 curated rules or your own ruleset, score it, measure rule coverage, classify ...
API Evangelist MCP Server
Model Context Protocol server over the same network — concierge tools (get_overview, guide_topic) plus find/get tools for every resource type, served over Streamable HTTP for AI...
API Evangelist APIs
Individual API resources tracked across the API Evangelist network, drawn from many providers and business sectors and accompanied by OpenAPI reviews.

The business reasons behind why we govern API operations — aligning the engineering side of operations with the business side of things.
API Evangelist Properties
Individual properties of API operations that can be linked to strategy, experience, and policies — and then governed to standardize how things work.
API Evangelist Rules
Technical details of API operations that can be automated and enforced, used to align policies with strategy to deliver the desired experience.
API Evangelist Schema
The naming and structure of the digital objects we pass back and forth via APIs within the business and personal applications we use.
API Evangelist Standards
Common Internet or industry standards used to consistently define API operations and keep the API factory floor well-defined and interoperable.

Open Collections 1
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).

OPEN COLLECTIONMCP Servers 2
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 SERVERPricing 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.

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.

SPECTRALSecurity Posture 2
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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 API Evangelist, 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.
