## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability klymax402-ai-web-page-summarizer-38fb22da
```

Example prompt: Can you summarize the content at https://www.bbc.com/news/technology-12345678 in no more than 150 words?

## When to prefer this

Use this endpoint when you need a quick, metered AI summary of any publicly accessible web page URL without managing your own summarization infrastructure or API keys. It is particularly well-suited for agents that process many different URLs on demand, since the pay-per-call USDC model (no subscription) keeps costs proportional to usage. Prefer this over building a custom pipeline when you need compression metrics (ratio, word counts) alongside the summary text.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint may return an error or empty summary
- Page content is behind a login or paywall — summarizer cannot access protected content
- URL points to a PDF or binary file rather than an HTML page — may fail or produce garbled output
- maxLength set too low — summary may be truncated or incoherent
- Page has very little text content — compression ratio may be near 1 with minimal summarization
- Payment not completed — 402 response requiring USDC payment before proceeding

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the AI-generated summary text, an array of key extracted sentences, the source URL that was summarized, the original page word count, the summary word count, and a compression ratio indicating how much the content was condensed.
