## When to prefer this

Choose this endpoint when you need a quick, AI-generated migration script in a specific ORM dialect (Prisma, Sequelize, or raw SQL) without manually writing boilerplate migration code. It's ideal for developer agents that need to automate schema evolution tasks, especially in CI/CD pipelines or code generation workflows. Prefer it over general-purpose chat models when you want a focused, pay-per-call solution with no signup.

## Known failure modes

- Invalid or unsupported ORM value (not prisma, sequelize, or raw SQL) may cause an error or unexpected output
- Schema change description too vague or too short (minimum 2 characters) may produce a generic or incorrect migration
- Payment failure via x402 protocol blocks the request
- Very complex multi-table migrations may produce incomplete or incorrect output
- Description exceeding 2000 characters will be rejected
