Build on the Financial OS.
90+ REST endpoints. Event-driven webhooks. Provider abstraction. Build anything.
REST API
90+ endpoints covering accounts, transactions, cards, analytics, payments, and administration. JSON responses, consistent error handling.
Event Webhooks
18 event types with configurable handlers. Real-time notifications for transactions, sync events, and alerts.
Provider Abstraction
Unified API across multiple banking and card providers. Write once, work everywhere. Automatic failover built in.
JWT Authentication
Secure token-based auth with automatic rotation, rate limiting, and comprehensive audit logging.
Quick Example
`bash
List all connected accounts
curl -H "Authorization: Bearer $TOKEN" \
https://api.corefinos.com/api/accounts
Response
{
"accounts": [
{
"id": "acc_01H...",
"institution": "N26",
"name": "Main Account",
"balance": 4250.00,
"currency": "EUR"
}
]
}
`
Every endpoint follows the same patterns: consistent JSON structure, proper HTTP status codes, and detailed error messages. Authentication via short-lived JWT tokens with automatic refresh.

“The API is clean, the docs are solid, and the event system actually works. I built a custom dashboard for our finance team in a weekend.”
