TapScanner (pdf.tap.scanner) Data API

TapScanner is a camera-to-PDF scanner and document editor from Tap AI whose heavy lifting is split between on-device text recognition and a set of cloud APIs. The app drives a multi-step server-side recognition pipeline (reserve a job, upload the scan, start recognition, poll for the result, then download per-page text), a document-conversion service that turns scanned PDFs into editable DOCX files, and a license-redemption call that unlocks premium features from a promo code. Every write call is gated by a Google Play Integrity token header, and the JSON payloads carry compact field names such as status, id, uploadURL, verified, redeemCode and deviceId.

Where teams use this data

• Document-intake automation

  Back-office pipelines drive the OCR job lifecycle — reserve an upload slot, kick off recognition, poll the result — landing searchable text in the DMS without a human opening the app.

• Bulk format conversion

  Contract and legal tooling batch-convert scans from PDF to DOCX for redlining, pushing files through the conversion endpoint and collecting editable documents.

• Entitlement verification

  Bundle partners verify redeem codes against device ids before granting premium features, keeping promotional licenses auditable.
