How this service works
Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.
Output
A JSON object containing the chosen style ('bullets' or 'paragraph') and the generated summary string — e.g. a newline-separated list of bullet points or a concise prose paragraph, derived strictly from the input text.
Example use cases
Earnings call digest for analyst
“Summarize this earnings call transcript into 5 bullet points, max 150 words — just the key financial highlights, no fluff: [transcript text]”
Multilingual news brief
“Take this English news article and summarize it into a short paragraph of about 80 words in Spanish: [article text]”
Meeting notes condensed
“I have these meeting notes — can you condense them into 3–6 bullet points, max 100 words, so I can share a quick recap with the team? [meeting notes text]”

Endpoint
GEThttps://freetier-agent-api.pages.dev/api/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.004/call), facts-only summary of a text block up to 12,000 characters, especially when output language control or bullet-vs-paragraph style selection is needed. Prefer it over larger LLM-based summarizers when cost and latency matter more than nuanced reasoning. Not suitable for documents longer than 12,000 characters or when summarization must cite sources or perform multi-document synthesis.
Side effects
- Input text exceeds 12,000 characters — request rejected or truncated
- max_words value outside 20–250 range — may return error or use default
- LLM inference timeout on Cloudflare Workers AI — returns 5xx error
- Invalid style enum value — may return default or error
- Empty or missing 'text' query parameter — returns 400 bad request
- Non-text or binary input — LLM produces nonsensical output
