```sh
zero fetch --capability superhighway-url-unfurl-page-to-markdown-80ca10bd

## When to prefer this

Use this endpoint when you have a specific URL and need its content as clean markdown for reading, summarizing, or quoting — particularly within an AI agent workflow that already uses Superhighway for web search, keeping all web access on one pay-per-call platform with no subscription required.

## Known failure modes

- URL is unreachable or returns a non-200 status — likely returns an error object
- Page is behind a paywall or login wall — content may be incomplete or empty
- URL points to a binary file (PDF, image) — markdown output may be empty or malformed
- Rate limit or payment failure — returns 402 if x402 payment not accepted
- Malformed URL input — validation error returned

## How this service works

Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.

## Output

Returns the full content of the requested URL rendered as clean markdown — stripped of ads, navigation, and boilerplate HTML — making it easy for an AI agent to read, summarize, or quote from the page.
