## When to prefer this

Choose this endpoint when you need deterministic, reproducible chunking of a campaign brief document specifically — with precise character-bound control and no AI-generated rewrites. Prefer it over general-purpose text splitters when you need guaranteed consistent output for downstream pipeline steps, or when working within a pay-per-call agent workflow at low cost ($0.01 USDC).

## Known failure modes

- Text exceeds 20,000 character limit — request rejected
- max_characters value outside 100–4000 range — validation error
- Empty or missing text field — may return empty chunk array or error
- Payment failure via x402 protocol — request not processed
