## 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 readable-batch-url-to-markdown-converter-d0b665ad -d '<json body>'
```

Example prompt: Fetch these three URLs and convert them all to clean markdown so I can use the content as context: https://example.com/article-1, https://example.com/article-2, and https://example.com/article-3.

## When to prefer this

Choose this endpoint when you need to convert multiple URLs to markdown in a single API call, reducing round-trip overhead compared to calling a single-URL endpoint repeatedly. It is ideal for RAG pipelines, research agents, and document ingestion workflows where you have a known list of URLs and want clean, LLM-optimized markdown with boilerplate stripped. Prefer it over generic scraping tools when the output format needs to be GFM-compliant with fenced code blocks and absolute links specifically for LLM consumption.

## Known failure modes

- Upstream page returns non-200 HTTP status (e.g. 404, 403) — individual result has ok:false with code 'upstream_status'
- URL is unreachable or times out — individual result fails with a network error code
- Malformed or invalid URL in the batch — result fails with a validation error
- Payment not completed or insufficient USDC balance via x402 — request rejected before processing
- Rate limiting or server overload — entire request may return 429 or 503
