## 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 tarnak-x402-toolkit-url-to-markdown-converter-e73fba24
```

Example prompt: Can you fetch https://techcrunch.com/2024/01/15/openai-latest-update/ and give me the clean article text in markdown format?

## When to prefer this

Choose this endpoint when an AI agent needs to ingest the readable text of a webpage without API keys or signup overhead, paying only $0.004 USDC per call via x402 on Base. It is especially useful for agents that need to read articles, documentation, or blog posts on-the-fly and require clean, LLM-ready markdown rather than raw HTML. Prefer it over browser-based scrapers when cost per call matters and the content is publicly accessible.

## Known failure modes

- URL is unreachable or returns non-200 status — API may return an error or empty markdown
- Paywalled or JavaScript-rendered pages may return incomplete or no content
- Invalid URL format in query parameter causes a 400-level error
- Rate limit: only 10 free verdicts per IP per day; beyond that, x402 micropayment required
- HTML that is too large or complex may be truncated or time out

## How this service works

Keyless pay-per-call APIs for AI agents on Base: token risk verdict, rug/honeypot report, gas estimate, URL-to-markdown and more. x402 v2, USDC, no API key or signup. 10 free verdicts per IP per day.

## Output
