## 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-to-markdown-converter-well-003-e19cc294 -d '<json body>'
```

Example prompt: Can you fetch the JSON at https://api.example.com/data/report.json and convert it to tidy markdown for me?

## When to prefer this

Choose this endpoint when you have a publicly accessible HTTPS URL whose response is JSON and you want a human-readable Markdown rendering of that data. It is ideal for documentation pipelines, report generation, or any workflow where JSON API responses need to be surfaced in a readable format. It is not suitable for local files, private network resources, non-JSON content, or payloads exceeding 1 MB.

## Known failure modes

- Non-HTTPS URLs (http, file, data, localhost, private IPs) are rejected with an error
- Response body exceeds 1 MB cap — returns error
- Fetch timeout after ~10 seconds — returns error
- More than 5 redirects followed — returns error
- URL does not return JSON content-type or parseable JSON body — returns error
- Payment not included or invalid — x402 payment required error

## 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 }.

## Output

Returns a JSON object containing: the original request URL, the final resolved URL (after redirects), the content-type of the fetched resource, the converted markdown string, and any warnings generated during conversion.
