## 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 url-to-markdown-converter-api-d47794b8
```

Example prompt: Can you fetch the article at https://en.wikipedia.org/wiki/Artificial_intelligence and return it as clean Markdown so I can use it in my document?

## When to prefer this

Choose this endpoint when you need to convert arbitrary public web pages to Markdown or plain text for LLM ingestion without setting up a dedicated scraping account. It is ideal for RAG pipelines, agent browsing tasks, and one-off URL reads where simplicity and low cost ($0.001/call) matter more than advanced scraping features like JavaScript rendering or login session handling.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error
- Target page blocks automated fetching or returns non-HTML content — may return empty or malformed output
- max_chars exceeded or ignored — content may be truncated unexpectedly
- Invalid or malformed URL input — returns validation error
- Render service cold start (Render free tier) — may cause high latency or timeout on first call
