## 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-4d04bd92 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you have a public HTTPS URL pointing to a JSON resource and need a human-readable Markdown representation of that data — ideal for generating documentation snippets, readable summaries, or formatted reports from API responses without writing custom rendering logic. Prefer this over general-purpose scrapers when the source is confirmed JSON and Markdown output is the desired format.

## Known failure modes

- Non-HTTPS URL provided (http, file, data, localhost, or private IP) — rejected with an error
- Source URL does not return a JSON content-type and body is not parseable as JSON — conversion fails
- Response body exceeds 1 MB cap — request is rejected or truncated
- Source URL takes longer than ~10 seconds to respond — timeout error
- More than 5 redirects followed — request is aborted
- Source server returns a non-200 status code — fetch error returned
- Malformed or deeply nested JSON that cannot be cleanly rendered as markdown — warnings field may indicate issues

## 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 with fields: url (original requested URL), final_url (URL after any redirects), content_type (detected content type of the source), markdown (the converted Markdown string), and warnings (any issues encountered during fetching or conversion).
