Developers

Build on the rails behind community lending.

The Qardon API exposes member onboarding, contributions, applications, repayments, and ledger reads. Production access is gated. Join the waitlist — we open the API to vetted institutional integrators first.

Open source

What we share publicly.

Our policy is conservative: the proprietary platform stays private; small developer tools, SDKs, and audit-helpful utilities ship public when ready.

⚑

Client SDKs

TypeScript and Swift SDKs for institutional integrators. MIT-licensed. Release schedule follows the production API.

≡

OpenAPI specs

Versioned OpenAPI 3.1 specs for every endpoint group. Auto-generated docs and codegen-friendly.

◎

Audit utilities

Form 990 Schedule R helpers, ECOA decision-tree linters, OFAC list ingestion tools — useful even outside our platform.

GitHub organization opens when we publish the first repository.
