How this service works
Summarize text: Verb-path alias of POST /v1/cheap-errand ($0.01 USDC). Same handler + payment terms; path defaults task=summarize when body.task omitted. Cheap agent glue for buyer-supplied text. Base via x402. No API key.
Output
A JSON response containing the processed output of the requested NLP task — e.g. a condensed summary string, a list of keywords, a sentiment label, a rewritten version of the text, or a translated passage, depending on the task specified (or defaulted from the path).
Example use cases
Condense long research report
“I have this 6-page research report on lithium battery supply chains — can you summarize it into 3–4 bullet points covering the main findings?”
Sentiment check on customer review
“Run a sentiment analysis on this customer review and tell me if it's positive, negative, or neutral: 'The onboarding was painless but the dashboard is confusing and support took 3 days to respond.'”
Extract keywords from blog post
“Pull out the top keywords from this blog post so I can tag it properly for SEO — here's the full text: [article text].”
