## When to prefer this

Choose this endpoint when you need a ready-to-use, versioned browser game save/replay ES module with the horizontal-15-d4 preset and want to customize only the title, seed, and accent color without building the persistence layer from scratch. It is ideal for rapid game prototyping or embedding a reproducible save system into an existing browser game at minimal cost.

## Known failure modes

- Title exceeding 80 characters or being empty returns a 400 validation error
- Seed value outside 0–2147483647 range returns a 400 validation error
- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Service unavailability returns a 503 error
