Why Lonca?

Live-verified

Every endpoint typed from a real SIT sandbox response, not just an OpenAPI spec.

Spec-faithful

Every method signature mirrors what Hepsiburada / Trendyol publish — including quirks like per-host path casing.

No magic

Plain fetch, plain TS. No code generation; no opaque proxies. Read the source.
