Technical details
Endpoint
POSThttps://twin.unykorn.org/ai/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, style-controlled text summarization with a strict word cap — especially when you need to choose between paragraph prose, a bulleted list, or a TL;DR format. Ideal for agents processing long documents, articles, emails, or contracts where output length must be predictable and controlled. The 24,000-character input limit makes it suitable for large documents.
Side effects
- Text exceeds 24,000 character limit — request rejected
- Invalid style value not in enum (paragraph, bullets, tldr) — validation error
- max_words outside 20-400 range — validation error
- Empty or missing text field — request fails
- Payment not included or insufficient — x402 payment required error
