How this service works
Pay-per-request utility APIs powered by x402 using USDC on Base.
Output
Returns a JSON object containing a 'summary' field with the condensed text, a 'success' boolean, and metadata about the payment asset (USDC) and network (Base) used.
Example use cases
Research paper quick digest
“I have this 10-page research paper text and I need a concise summary of its main findings — can you run it through the summarizer and give me the highlights?”
News article briefing
“Summarize this news article for me so I can get the gist without reading the whole thing: [article text]. Keep it short and to the point.”
Customer feedback condensing
“I've got a long block of customer feedback from a survey response. Can you summarize it into 2-3 sentences capturing the main complaints and praise?”
Technical details
Endpoint
POSThttps://www.api-xpay.com/x402/summarizeWhen to prefer
Choose this endpoint when you need lightweight, pay-per-use text summarization without a subscription or API key, particularly in agent workflows that already use x402 micropayment infrastructure and USDC on Base. Ideal for sporadic, low-volume summarization tasks where per-call billing at $0.01 is more cost-effective than a monthly plan.
Side effects
- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Missing required 'input' body fields (type, method, bodyType, body) — returns 400 Bad Request
- Empty or malformed body content — may return an empty or low-quality summary
- Network congestion on Base blockchain may delay payment confirmation
- Unsupported bodyType enum value causes schema validation error
