The live Realie API serves the v3 data generation only — the previous generation’s data is retired. This tab documents the v2-compatible response shape: the flat field layout existing integrations receive, produced from v3 data through a compatibility layer. The new standard is the full nested record documented in the v3 API reference; migrate with the v2 → v3 migration guide.
The v2 shape is not a separate dataset: requests to the documented endpoints return v3-generation data in the v2-compatible response shape. There is no version header or parameter that returns the old data — it no longer exists. What that means in practice:
  • Endpoint pages in this tab still work — the playground calls the live API — but responses reflect the v3 data generation, so field values (and a small number of field names) can differ from the frozen examples here. Coded values stored before August 19, 2026 decode against the Pre-v3 Code Tables (Frozen) archive; current values decode with the v3 Feature Field Key.
  • Most v2 integrations run unchanged. The response shape is v2-compatible; the deltas are catalogued field-by-field in the migration guide.
  • No sunset date has been announced for this reference. It will remain available while v2-era integrations are active.
