# BookFold

BookFold is an MPP-paid API for summarizing PDF and EPUB books.

## Flow
1. POST /v1/uploads with fileName, sizeBytes, and optional contentType.
2. Use the returned upload.clientToken to upload the file with PUT.
3. POST /v1/quotes with uploadId and detail.
4. POST /v1/jobs with quoteId.
5. If the server returns 402, pay the MPP challenge and retry the same POST /v1/jobs request.
6. Poll GET /v1/jobs/{jobId} until the status is succeeded or failed.

## Notes
- Supported input: PDF and EPUB
- Max upload size: 50 MB
