Documents are the core assets in DocIntell. When you upload a PDF, it’s stored in our Cold Vault — an immutable, SEC 17a-4 compliant storage system.
Document Lifecycle
Upload
Send a PDF to POST /v1/documents. The file is validated (PDF only, max 100MB).
Cold Vault Storage
The original file is stored in Google Cloud Storage with Object Retention Lock.
This creates an immutable record that cannot be deleted during the retention period.
Extraction Queue
A job is created and published to our processing queue. You receive a 202 Accepted response.
Processing
Extraction workers process the document using AI models.
Hot Index
Extracted data is stored in our Hot Index for fast queries (under 100ms).
Two Storage Tiers
DocIntell uses a Hot/Cold architecture to balance performance with compliance requirements.
| Tier | Purpose | Key Features |
|---|
| Cold Vault | Immutable compliance storage | GCS with Object Retention Lock, SEC 17a-4 compliant, WORM |
| Hot Index | Fast queryable database | Cloud SQL, sub-100ms queries, multi-tenant with RLS |
Retention Periods
When uploading, specify the retention period (1-10 years, default 7):
curl -X POST https://api.docintell.com/v1/documents \
-H "Authorization: Bearer dk_live_YOUR_API_KEY" \
-F "file=@document.pdf" \
-F "retention_years=7"
Once set, retention periods cannot be shortened. Documents are automatically deleted after expiry.
