Run it

One call presses the Widget and answers the run once its status is succeeded or failed, however long it takes. The key is read from ABYSS_API_KEY. Install the library with npm install abysshub or pip install abysshub; cURL sends the Fields as a form.

JavaScript

Copy// index.mjs
import Abyss, { file } from "abysshub";

const abyss = new Abyss();

const run = await abyss.run("widget_360", {
  input: file("report.pdf"),
});

for (const path of await run.save("output")) {
  console.log(path);
}

Python

Copyfrom abysshub import Abyss, file

abyss = Abyss()

run = abyss.run("widget_360", {
    "input": file("report.pdf"),
})

for path in run.save("output"):
    print(path)

cURL

Copycurl https://api.abysshub.com/v1/widgets/widget_360/runs \
  -H "Authorization: Bearer $ABYSS_API_KEY" \
  -F input=@report.pdf

A succeeded run carries its result and its output_files. Their URLs are signed for each read: re-read the run, never store a URL. A run still queued or running in the answer (after an hour, or when the API is busy) is read again at its Location with ?wait=true.
