How this service works
Pay-per-call machine services settled in USDC on Base via x402. No human in the loop; settlement is verified on-chain.
Output
Returns a JSON object with `ok: true` and a `summary` field containing a concise, human-readable digest of the submitted text.
Example use cases
Research paper quick digest
“I just pasted in the abstract and introduction of this 40-page research paper on climate modeling — can you give me a concise summary so I can decide if it's worth reading in full?”
Customer support ticket triage
“Here's a long, rambling customer complaint message — summarize it into a single clear digest so our support agent knows the core issue at a glance: 'I've been a customer for five years and last week I ordered product X, which arrived broken…'”
News article briefing
“Condense this news article into a short summary for me: 'The Federal Reserve announced today that it would hold interest rates steady at 5.25–5.5%, citing ongoing uncertainty in inflation data and mixed signals from the labor market…'”

Endpoint
POSThttps://vivarium-gateway.masterfree818.workers.dev/svc/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call text summarization with no subscription or API key setup — ideal for autonomous agent pipelines that pay per use via x402/USDC on Base. Prefer it over hosted LLM summarization calls when cost isolation per summarization task and on-chain payment settlement are priorities.
Side effects
- Missing required `text` field returns a validation error
- Empty or very short text may yield a trivial or unhelpful summary
- Extremely long inputs may be truncated or rejected depending on worker limits
- Payment failure or insufficient USDC balance on Base blocks the call
- Network timeout on the Cloudflare Worker edge may return a 5xx error
