    "summary": "Read-only JSON API describing the Watermelon Studio product engineering studio and its case studies.",
    "description": "A small public API so agents and scripts can read Watermelon Studio's case studies and studio facts without scraping HTML. No authentication is required.\n\n**Versioning.** The current version is v1, addressed at `/api/v1/*`. The unversioned `/api/*` paths are aliases of the newest version and may change when a new version ships; integrate against `/api/v1/*` for stability. Every response carries `X-API-Version`. A request for a version that does not exist returns 404 with `error.code = unsupported_version`.\n\n**Deprecation policy.** A version stays available for at least 6 months after its successor ships. Once a version is deprecated its responses carry `Deprecation: true` and a `Sunset` date (RFC 8594, RFC 9745); the replacement is named in `error.hint` and in the `Link` header. Breaking changes never land inside a version.\n\n**Rate limits.** Roughly 600 requests per 60 seconds per client IP, enforced per Cloudflare edge location, so the budget is approximate rather than global. Responses carry `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset` and `RateLimit-Policy`. Exceeding it returns 429 with `Retry-After`.\n\n**Markdown.** Every page of the website also answers in Markdown when the request carries `Accept: text/markdown`.\n\n**MCP.** The same data is exposed as MCP tools over Streamable HTTP at `/mcp`, described at `/.well-known/mcp`.",
