Olik Split
Public API · v1

Drop-in expense splitting, shared budgets and receipt OCR for your app.

One REST API. Server-side OCR, debt simplification, webhook delivery, and GDPR-ready data flows — wired in days, not months.

No card required. Test-mode keys are sandboxed end-to-end.

Server-side receipt OCR

POST an image, get structured line-items with merchant, total, currency, date and per-line categories.

Debt simplification

Net IOUs across a group in one API call. Settlement suggestions ranked by transfer count.

HMAC-signed webhooks

Stripe-style signatures with key rotation overlap. Every expense, settlement and budget event delivered with retries.

Test + live modes

Separate sandboxed tenants for development. Test keys never touch live data.

GraphQL-free, REST-first

Predictable resource URLs, JSON bodies, ISO-8601 timestamps. No client SDK required to integrate.

GDPR ready

User-scoped export and delete endpoints. DPA available. Sub-processor list published.

Built for partner integrations

Whether you ship a roommate app, a travel companion, a community manager or a group-chat add-on — the same SDK handles the splitting and reconciliation, you keep the UX.

  • Per-customer data isolation enforced at the database layer.
  • API key rotation with overlap window — zero-downtime key swaps.
  • Webhook signing secret rotation with dual-sign during cutover.
  • EU data residency · audit log on every internal mutation.
