Cloud9 Esports, Inc. is a North American professional esports organization founded in 2013 by Jack and Paullie Etienne and headquartered in Santa Monica, California. It fields competitive rosters across League of Legends, VALORANT, VALORANT Game Changers, Call of Duty and Rainbow Six, and its trophy case includes the inaugural Overwatch World Championship, the 2018 Rocket League World Championship, multiple LCS titles and a Counter-Strike Major. Beyond competition it runs Club9 (a membership and fan community at club9.cloud9.gg), an official Shopify merchandise store at store.cloud9.gg, and a content and creator division. Cloud9 publishes no developer program and no OpenAPI, but its public web estate is machine-readable: cloud9.gg runs on WordPress and serves an anonymous, unauthenticated WordPress REST API at /wp-json/ covering news posts, pages, media and the Cloud9-specific players, teams, achievement and case-study content types, alongside a remote Model Context Protocol server advertised through RFC 8414 and RFC 9728 discovery metadata.
Cloud9 publishes 3 APIs on the APIs.io network. Tagged areas include Company, Esports, Gaming, Entertainment, and Media.
Cloud9’s developer surface includes engineering blog, support, signup flow, authentication, and 23 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cloud9: open an issue to ask a question, or submit a pull request to add artifacts.

name: Cloud9 WordPress REST API
description: 'cloud9.gg runs on WordPress (WP Cloud / Automattic Atomic hosting) and serves the standard WordPress REST
API anonymously at https://cloud9.gg/wp-json/. The discovery index enumerates 277 routes across 14 namespaces; the wp/v2
namespace alone carries 118 routes. Read access requires no credentials and no key. Alongside the core content types (89
posts, 17 pages, 1,175 media items, 19 categories, 3 users, a 769-item search index) the site registers four Cloud9-specific
custom post types that make the roster and record queryable: players (47), teams (45), achievement (564) and case-study
(7). Responses carry X-WP-Total and X-WP-TotalPages pagination headers and RFC 8288 Link headers, and every collection
publishes a real JSON Schema over HTTP OPTIONS. Write operations are advertised on the same routes but require WordPress
authentication (application passwords), so the public surface is read-only.'

note: 'This is the WordPress platform REST API as deployed on the Cloud9 site, not a bespoke Cloud9 developer API. Cloud9
publishes no OpenAPI and no developer documentation for it; the contract recorded here was read from the live discovery
index and from HTTP OPTIONS schema responses on each collection. No Documentation or APIReference pointer is emitted
for this API: the only reference that describes it is WordPress''s own upstream documentation, which Cloud9 neither
authored nor links to, and crediting Cloud9 with it would overstate what this company publishes.'
- aid: cloud9:mcp-server
name: Cloud9 MCP Server
description: A remote Model Context Protocol server published on cloud9.gg and advertised through RFC 8414 OAuth authorization-server
metadata and RFC 9728 protected-resource metadata. It is the WordPress MCP adapter fronting the Cloud9 content estate,
exposed at the WordPress REST namespace `mcp` with two servers — mcp-oauth-server and mcp-adapter-default-server — plus
the companion wp-abilities/v1 namespace. Authorization is OAuth 2.1 authorization code with PKCE (S256), a single coarse
`mcp` scope, public clients (token_endpoint_auth_method none) and client-ID metadata documents rather than RFC 7591 dynamic
registration. An anonymous tools/list call returns 401 with a well-formed WWW-Authenticate Bearer challenge carrying the
resource_metadata pointer, so the live tool list and per-tool inputSchema require an authorized session. No tool inventory
is published anywhere public, so none is recorded here.

anonymous product and collection JSON endpoints on it — /products.json returns the live catalogue with variants, prices,
options and images, and /collections.json returns the storefront collections. These are platform endpoints Shopify exposes
by default rather than a Cloud9-authored API, and Cloud9 documents neither, but both return 200 to an unauthenticated
client and are the only machine-readable view of Cloud9 commerce.
