1. Upload your files via POST /api/v1/jobs/upload — get a cost preview without spending credits
2. Confirm the job via POST /api/v1/jobs/{job_id}/confirm — credits are deducted, processing begins
3. Poll the job status via GET /api/v1/jobs/{job_id} until status is done or error
4. Download the result via GET /api/v1/jobs/{job_id}/download?type=csv_basic|md|xlsx_basic
