Catalog API - Claude Code Templates

The catalog is published as static JSON under https://www.aitmpl.com/api/v1/. No key, no rate limit beyond normal CDN caching. The full reference and stability policy live at aitmpl.com/developers/catalog-api; this page is the short version.

File	Contents
`catalog.json`	Every component
`catalog/{type}.json`	One type: `agents`, `commands`, `mcps`, `settings`, `hooks`, `skills`, `loops`, `mods`
`version.json`	`schemaVersion`, `generatedAt`, `sha256`, counts. Poll this, then fetch the catalog only when `sha256` changes
`schema.json`	JSON Schema (draft 2020-12) for all of the above

Stability

Within v1 every change is additive: fields are added, never removed or renamed.
A breaking change ships at /api/v2/, and v1 stays published for at least six months.
Components are ordered by id. Sponsored placements are never part of this API.
Every format change is recorded in the Catalog API changelog.
