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.
Example use cases
API response to markdown documentation
“Take the JSON response from https://api.github.com/repos/openai/openai-python and convert it to markdown so I can paste it into our README.”
Render config file as readable markdown
“Fetch https://myapp.example.com/config.json and turn it into nicely formatted markdown — I need to share it with the team in a doc.”
Inspect third-party API output as markdown
“Can you grab the JSON from https://jsonplaceholder.typicode.com/todos/1 and convert it to markdown so it's easier to read?”
Technical details
Endpoint
POSThttps://well-003-json-to-markdown.rainmaker-wells.workers.dev/api/json-to-markdown?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
