## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call summarization API that accepts crypto micropayments via x402 on Base. Ideal for agents that process variable volumes of text without committing to a subscription, or for pipelines where per-call USDC billing is preferred over API keys. Best suited for text under 4,000 characters that needs structured output including summaries, action items, and takeaways in a single call.

## Known failure modes

- Text exceeds 4000 character limit — request rejected with validation error
- Empty or missing text field — returns error requiring minLength of 1
- Payment not included or insufficient USDC — x402 payment required response
- Malformed JSON body — returns 400 bad request
- Instruction exceeds 500 character limit — rejected with validation error
