How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
A JSON object containing a 'summary' field with a concise, natural-language summary of the input text. The summary distills the main ideas or key points of the provided content into a shorter form.
Example use cases
Research paper quick digest
“I've got this 8-page research paper on climate change policy — can you summarize it into a few sentences so I can get the gist without reading the whole thing?”
News article briefing for agents
“Summarize this news article for me: 'Global markets fell sharply today as inflation data came in hotter than expected, with the S&P 500 dropping 2.3%...' — just the key takeaway in one or two sentences.”
Long email thread condensation
“This email thread between my team is getting really long. Can you condense it down to a summary of what's been decided and what's still outstanding?”
Technical details
Endpoint
GEThttps://agentpay.help/v1/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need frictionless, pay-as-you-go text summarization with no account setup or API key management. It is ideal for AI agents operating autonomously with a crypto wallet (USDC on Base), where traditional API key provisioning is impractical. Best suited for lightweight, one-off summarization tasks billed at $0.01 USDC per call rather than subscription-based NLP APIs.
Side effects
- Payment failure or insufficient USDC balance — the x402 protocol returns 402 Payment Required if the micropayment is not completed
- Input text too long or exceeding token limits — may result in truncation or an error response
- Empty or missing input text — likely returns an error or empty summary
- Network timeout — the endpoint may not respond if the AI backend is overloaded
- Invalid request format — missing required body fields may result in a 400 Bad Request
