Getting started with Donala
Set up your memory space, connect your Postgres DB, and make your first API call in under 5 minutes.
Memory spaces explained

Instructions and scheduling
Lock in persistent AI behaviour with immutable instructions and set up time-based reminders.
Integration
The whole setup is one call
Donala connects to the PostgreSQL database for your memory. Create a memory, connect its database, then add its key to your server-side integration.
- ⌗One API key, one connection string
- ⬡Write and recall in any language
- ▦Memory persists across restarts
- ⌥GDPR: delete a tenant in one call
curl -X POST https://api.donala.ai/api/memory/write/ \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"id":"msg-001","session_id":"sess-abc",
"role":"user","content":"Hello","scope":"global"}'
curl -X POST https://api.donala.ai/api/memory/recall/ \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query":"hello","limit":8}'→ Create a new production key in Dashboard → API Keys, copy it once, then place it in your application's server-only DONALA_API_KEY environment variable. Existing key prefixes are not usable credentials.
