## 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 json-url-to-markdown-converter-9efa35f9 -d '<json body>'
```

Example prompt: Can you fetch the JSON at https://api.example.com/data/products.json and convert it into clean, readable markdown for me?

## When to prefer this

Choose this endpoint when you have a publicly accessible HTTPS URL that returns JSON and need a human-readable markdown representation of that data — for example, for documentation, sharing API output, or rendering structured data in prose. It handles fetching and conversion in one step with no storage of data. Not suitable for local/private URLs, non-JSON content, large payloads over 1 MB, or any URL not reachable publicly over HTTPS.

## Known failure modes

- Non-HTTPS URLs (http, file, data, localhost, private IPs) are rejected with an error
- URLs returning non-JSON content types and non-parseable bodies are rejected
- Responses larger than 1 MB are rejected due to body size cap
- Requests timing out after ~10 seconds are rejected
- URLs requiring more than 5 redirects are rejected
- Network errors or unreachable hosts result in failure

## How this service works

Convert a public https URL that returns JSON to tidy markdown ($0.005 USDC via x402). https only — http, file, data, localhost, and private IPs are rejected. Caps: 1 MB body, ~10s timeout, max 5 redirects. Requires JSON content-type or a parseable JSON body. Returns JSON { url, final_url, content_type, markdown, warnings }. Provided as is, with no warranty or guarantee of accuracy or fitness. Nothing is stored.

## Output

Returns a JSON object containing: the original URL, the final URL after any redirects, the detected content type, the converted markdown string, and any warnings encountered during fetching or conversion.
