The full engineering changelog lives in the backend repo (backend/docs/api/CHANGELOG.md). This page mirrors the user-facing highlights. We follow Keep a Changelog and semantic-ish versioning — breaking changes always ship under a new URL prefix (/api/v2/*), and /api/v1/* stays live for at least 12 months after any major version bump.

​
Unreleased (v1.0.0-alpha)

  • Sales search modes: sales runs use the economy search mode by default and report the mode used in a new search_mode response field. Organizations can ask support to enable quality, which also reads whole public groups. See Search modes.
  • Sales discovery — POST /sales/runs investigates potential buyers from a business prompt. Poll GET /sales/runs/{run_id} for the answer and public source evidence. Supports organization-scoped idempotency and optional waiting up to 25 seconds. See the Sales agent guide.
  • Sales run execution — the API deployment starts its sales queue consumer automatically, so accepted searches are processed in the background.
  • Generic LLM invocation — POST /llm/invoke accepts messages and returns text, JSON, or JSON matching your schema. Reuses API-key authentication and organization credits; optional user/session IDs provide attribution.
The initial API surface. Everything below is new.

​
Endpoints

  • Self-service signup — POST /signup creates a workspace org and your first API key in one call (Firebase-authed).
  • Organization key management — POST / GET / DELETE /organizations/{org_id}/api-keys.
  • Identity — GET /verify validates a key and returns org context.
  • Preflight — POST /preflight dry-runs a request through the LLM validator without spending credits.
  • File uploads — POST /files for generic files.
  • Image uploads — POST /images with tags/caption, plus full CRUD (GET /images, GET /images/{id}, DELETE /images/{id}).
  • Generation (natural language) — POST /excel/generate, POST /word/generate, POST /slides/generate. Sync (default) or async: true. Resume via run_id.
  • Excel analysis — POST /excel/analyze returns a JSON answer against an uploaded workbook.
  • Slide outlines — POST /slides/outline for preview-before-generate workflows.
  • Tasks — GET /tasks/{task_id} for async polling.
  • Runs — GET /runs, GET /runs/{id}, GET /runs/{id}/download, POST /runs/{id}/export (PDF / CSV / PNG / etc.).
  • Webhooks — POST / GET / DELETE /webhooks for subscriptions, plus per-request webhook_url on generation endpoints.
  • Embedded editor — every completed run includes an edit_url your app can iframe.

​
Features

  • Sync and async modes on every generation endpoint — sync promotes to async automatically at the 300s ceiling.
  • Run resume semantics — pass run_id to iterate on the same document without re-explaining what it is.
  • Preflight LLM validator — rejects requests referencing missing assets before spending real credits.
  • HMAC-signed webhooks — SHA-256, replay-protection timestamp, 7 retry attempts with exponential backoff.
  • Credit ledger — every movement logged for audit.
  • Org-scoped tenancy — every resource lookup enforces (caller_org == resource_org) — no cross-tenant leaks.

​
Supported formats

  • Excel: .xlsx primary, exports to pdf / csv / png / html
  • Word: .docx primary, exports to pdf / html / txt / odt
  • Slides: .pptx primary, exports to pdf / png / odp

​
Current limitations

  • Personal vs. workspace key scoping — available via the dashboard key-creation flow; every key inherits the creator’s current workspace role.
  • Text and static visuals only — no audio or video generation.
  • Slides: max 30 slides per call. Larger decks should be built in chunks via run_id resume.
  • Webhooks fire on run.completed and run.failed only.

​
Versioning policy

  • URL-based: breaking changes land at /api/v2/*; /api/v1/* stays live for at least 12 months.
  • Additive changes (new endpoints, new optional fields, new enum values, new error codes) are always safe within v1.
  • Breaking changes require a deprecation window:
    • Announce here + email notice.
    • Response includes X-Deprecated: true and Sunset: <date> headers for 12+ months.
    • Removal only on the v2 boundary.
