Changelog

Reverse-chronological. Breaking changes call out the migration explicitly.

2026-06 — v1 launch

Initial Inferio public release. Headline pieces of the surface:

API

  • POST /api/v1/ocr/upload-sessions — create a session
  • POST /api/v1/ocr/upload-sessions/{id}/files — upload PDFs / images
  • POST /api/v1/ocr/requests — kick off OCR against a built-in template or custom JSON schema
  • GET /api/v1/ocr/{requests,documents} — cursor-paginated list APIs
  • POST /api/v1/ocr/{documents,requests}/{id}/retry — re-run a page or whole batch (failed/rejected only; never double-bills successful pages)
  • GET /api/v1/ocr/dashboard — today / yesterday aggregates + realtime live counts

Auth: Bearer token (inf_dev_* or inf_live_*) + X-Merchant-ID header on every call. See Authentication.

Document templates (pre-tuned JSON schemas)

  • Trade invoice (JP) — T-number + 8/10% tax, NTA live validation
  • Letter of credit — 40+ fields including Incoterms
  • Bank statement — IBAN / BIC + balances
  • Payroll record — salary / deductions / tax
  • KYC / ID document — MRZ + identity fields
  • Receipt / expense — merchant / tax / category
  • Custom schema — bring your own JSON shape

Webhooks

  • ocr.request.created, ocr.document.processing, ocr.document.completed — three events per request lifecycle
  • HMAC-SHA256 signed (X-Inferio-Signature: t=...,v1=...)
  • 5-minute replay window
  • 24h key-rotation grace
  • 6-attempt retry over ~24h, dead-letter outbox for failures past that

Compliance

  • Real-time T-number verification against the JP National Tax Agency public API (every invoice extraction includes t_number_valid)
  • Cryptographically timestamped archive — Electronic Bookkeeping Law compliant by default, 7-year retention
  • Per-field confidence scores 0.0–1.0; anything below 0.75 surfaces in the correction UI before sync

Dashboard

  • Drag-drop upload (up to 20 files per session)
  • Real-time request status + per-document review queue
  • freee + MoneyForward OAuth sync — extracted invoices land as journal entries
  • Webhook endpoint manager with test-event button + rotate-with-grace secrets
  • Audit-trail export per request

Known gaps (roadmap)

  • Idiomatic Node / Python / Go SDKs — REST API works today; SDKs ship next
  • Per-endpoint scoped API tokens (today’s tokens are merchant-wide)
  • On-prem model deployment for max data isolation (enterprise-only today, formalised path coming)
  • SOC 2 Type II certification — in progress
