Example prompt: Give me a philosophical meditation on cherry blossoms and the beauty of fleeting, time-limited moments — something I can sit with to appreciate opportunities before they pass.

## When to prefer this

Choose this endpoint when you need a ready-made, poetic philosophical meditation specifically on impermanence, fleeting beauty, and time-limited opportunities — framed through the lens of cherry blossoms. It is distinct from the sibling endpoints (e.g. Rosemary for memory/persistence, Pine for clarity/simplicity) and is the right pick when the intent is explicitly about ephemerality or appreciating what won't last.

## Known failure modes

- Network or server unavailability returning a 5xx error
- Payment failure or insufficient USDC balance preventing access (402 response)
- Empty or malformed response body if the service is misconfigured
- Rate limiting if called too frequently in succession
