Document workflows

Everything an agent does to a document, in one shop, pay-per-call:

Prepare (deterministic, no LLM)

POST /v1/pdf-info    $0.001  pages, metadata, scanned-or-not
POST /v1/pdf-pages   $0.002  pull just the pages you need
POST /v1/pdf-merge   $0.003  combine 2-10 PDFs

Read (hallucination-guarded)

POST /v1/parse  PDF -> structured Markdown; scanned pages get
                dual-engine consensus OCR with calibrated confidence
POST /v1/ocr    single image -> text, Japanese-strong

Check

POST /v1/verify             invoice arithmetic + registration checks
POST /v1/document-pipeline  all of the above in one $0.05 call

Tip: run pdf-info first - it tells you whether a document is scanned before you pay parsing prices.
