API

These routes run on the Prepress Buddy server. The upstream FastAPI key never reaches the browser — requests are proxied server-side.

Method	Path	Description
POST	/api/upload	Upload a file. Multipart: file, mode (pdf\|image), operations (JSON), outscale.
GET	/api/jobs/{id}	Job status: status, progress, step, error.
GET	/api/jobs/{id}/result	Completed job result JSON (preflight or restoration).
GET	/api/jobs/{id}/files/{name}	Download an output file. Whitelisted names only.
POST	/api/jobs/{id}/upscale	Second-pass upscale. Body: { factor: 2 \| 4 \| 8 }.
POST	/api/jobs/{id}/restore-faces	Second-pass face restoration. Body: { preset }.
GET	/api/jobs/{id}/bundle	All outputs for the job as a ZIP archive.
GET	/api/health	Backend and GPU worker status.

Example — upload and poll

const fd = new FormData();
fd.append('file', file);
fd.append('mode', 'image');
fd.append('operations', JSON.stringify({ upscale: true, sharpen: true }));
fd.append('outscale', '2');

const { job_id } = await fetch('/api/upload', { method: 'POST', body: fd })
  .then(r => r.json());

// poll until complete
let state;
do {
  await new Promise(r => setTimeout(r, 2000));
  state = await fetch(`/api/jobs/${job_id}`).then(r => r.json());
} while (state.status !== 'completed' && state.status !== 'failed');

const result = await fetch(`/api/jobs/${job_id}/result`).then(r => r.json());
