JSON and presets

Send JSON to this site’s demo echo endpoint; replace the base URL with your API in an application.

import { Http, envelope } from "fetchzen";
const api = Http.create(`${location.origin}/api/examples/`, {
  cache: false, secure: false, preset: envelope,
});
const result = await api.post("echo/", JSON.stringify({ name: "Ada" }));
console.log(result.payload);

Request parameters

Name

Only Run sends a request to this site's demo API. Use synthetic data only; do not send secrets or personal files. Uploads are counted, not stored.

Run Cancel

Ready. No request sent.

Result

Choose Run to see the response.

Event log

No events yet.

What to notice

envelope unwraps data; bare and problem preserve the JSON body. Try GET and POST. The bounded demo echoes only string name and message fields. secure: false is for these public demos, not a recommendation for authenticated APIs.

Next: validation or presets.
