How this service works
Pay-per-call machine services settled in USDC on Base via x402. No human in the loop.
Output
Returns a JSON object with ok: true and a summary field containing a concise prose digest of the submitted text.
Example use cases
Research article digest for analyst
“Here's a 3,000-word research paper — can you boil it down to a concise digest so I can decide whether it's worth reading in full?”
Long email thread TL;DR
“This email thread is way too long to read right now. Can you summarize what's being discussed and what decisions were made?”
News article quick summary
“Summarize this news article in a few sentences so I can get the gist without reading the whole thing.”
Technical details
Endpoint
POSThttps://api.altahub.net/svc/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call text summarization with no API key management — ideal for agent workflows that process variable volumes of text and want USDC micropayment settlement on Base rather than a subscription model.
Side effects
- Missing required 'text' field returns a validation error
- Empty or extremely short text may produce a trivial or unhelpful summary
- Very long inputs may be truncated or may hit payload size limits
- Payment failure (insufficient USDC balance) results in a 402 response before processing
- Network timeouts for unusually large text inputs
