Public resources // Read-only

Excelsior Creative developer resources

These resources help developers and AI agents understand the public Excelsior Creative website without guessing about private capabilities. The supported public API is deliberately small: it provides read-only search across published articles, projects, and industry pages.

Machine-readable interfaces

OpenAPI 3.1

A machine-readable contract for the website's intentionally public, read-only content-search operation.

GraphQL

Payload CMS exposes a GraphQL endpoint for published content. It is CMS-managed and is not a promise of anonymous mutation access.

Contract boundaries

Contact submission, article and image generation, scheduled jobs, cache revalidation, Payload administration, and other authenticated operations are internal website capabilities. They are intentionally absent from the public OpenAPI contract and must not be invoked as public tools.

Authenticated documentation

Excelsior Creative also maintains authenticated documentation and MCP infrastructure for authorized users. Those systems are separate from this marketing website and do not provide a public self-service account, sandbox, API key, or MCP tool suite.
