How this service works
Summarize text: send any text, get a short summary written by Claude, with a word limit you choose.
Output
A plain-text summary of the submitted content, capped at the requested word count (default 60 words, max 250). The endpoint refuses input longer than 8,000 characters rather than silently truncating it.
Example use cases
TL;DR for long research articles
“Here's a 5,000-word research paper on climate change — can you give me a 100-word summary of the key findings?”
Condense customer feedback for dashboards
“I have a long customer review here — summarize it in about 60 words so I can show it on our feedback dashboard.”
Shorten product descriptions for email
“This product description is way too long for our newsletter — can you condense it to 50 words max?”
Technical details
Endpoint
POSThttps://web.tollkit.dev/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-as-you-go text summarization with no API key setup, especially in agentic or automated workflows where per-call micropayments via x402/USDC are acceptable. Ideal for summarizing individual documents or passages under 8,000 characters without committing to a subscription-based NLP service.
Side effects
- Input text exceeds 8,000 characters — endpoint returns an error/refusal rather than truncating
- max_words value above 250 is clamped silently to 250
- Payment fails or is insufficient via x402 — call is rejected with a 402 response
- Empty or missing text field — likely returns an error
- Network timeout on slow connections
