# Changelog

**Added** — Public API v1 launch: searches, papers, documents, chats,
extractions, paraphrases, ai-detections, topics, citations, files,
jobs, usage.

**Added** — `SciSpace-Version: 2026-08-01`, the first dated version. Pin it; requests without the
header resolve to the oldest supported version. See versioning.

**Added** — Cursor pagination on every list endpoint, idempotency keys on every `POST`, and the
`X-Request-Id` / `X-RateLimit-*` / `X-Credits-*` response headers. See conventions.

**Added** — Webhook endpoints with signed deliveries, so async work no longer needs polling.
See webhook-endpoints.
