Changelog

Changes to the ODEN API, newest first. Backwards-incompatible changes will always be called out here.

v1.0.0 — 2026-07-30#

First public version of the API.

• POST /search — the single search endpoint: synthesized answer plus ranked citations as JSON.
• Parameters: query, answer, depth (advanced / basic), include_snippets.
• Response: query, trace_id, cached, and results with answer and citations[] (title, url, score, optional snippet).
• Bearer-token authentication with per-key usage metering.
• Free (1,000/mo), Pro (€29/mo, 6,000) and one-time top-ups.
• GET /health — service status, no auth.

This is the baseline. Future entries will record new parameters, response fields and any behaviour changes with the date they shipped.
