WorldMonitor composes a per-user intelligence brief on Railway, stores each
edition in Redis at brief:{userId}:{issueSlot}, writes a latest pointer at
brief:latest:{userId}, and exposes these routes for dashboard readback,
public sharing, and Telegram/Slack carousel rendering. Default cadence is
daily, but each alert rule’s digestMode can schedule daily, twice-daily, or
weekly editions.
For source selection, filtering, deduplication, LLM grounding, and bias
controls, see News Digest and Briefing Methodology.
All read routes require a valid Clerk session and a PRO tier, except the public share route (/api/brief/public/{hash}).
Latest brief (authenticated)
GET /api/latest-brief
Returns a short summary of the caller’s most recent composed brief, or
{ status: "composing" } if the requested/current slot has not produced a
brief yet.
| Status | Response |
|---|
| 200 OK | { status: "ready", issueDate, issueSlot, dateLong, greeting, threadCount, magazineUrl } |
| 200 OK | { status: "composing", issueDate, issueSlot? } — no brief for the current/requested slot yet |
| 401 | Missing / invalid Clerk JWT |
| 403 | pro_required |
| 503 | BRIEF_URL_SIGNING_SECRET not configured |
issueDate remains the display/date field (YYYY-MM-DD). issueSlot is the
frozen edition key (YYYY-MM-DD-HHMM) used for Redis lookup and HMAC binding;
it is present on ready responses and on misses for an explicitly requested
slot. The magazineUrl is freshly signed against {userId, issueSlot} so it
only works for the authenticated owner.
GET /api/brief/{userId}/{issueSlot}
Full magazine reader for issueSlot (YYYY-MM-DD-HHMM). HMAC-signed URL
required. The slot format lets two same-day digest sends produce distinct
frozen editions.
Sharing
POST /api/brief/share-url?slot=YYYY-MM-DD-HHMM
Materialises a public share pointer for the caller’s brief on slot. If the
slot is omitted, the route resolves brief:latest:{userId}. Idempotent — hash
is a pure function of {userId, issueSlot, BRIEF_SHARE_SECRET}.
| Status | Response |
|---|
| 200 | { shareUrl, hash, issueSlot } |
| 400 | invalid_slot_shape / invalid_payload |
| 401 | UNAUTHENTICATED |
| 403 | pro_required |
| 404 | brief_not_found — reader can’t share what doesn’t exist |
| 503 | service_unavailable |
GET /api/brief/public/{hash}
Unauthenticated public read of a previously-shared brief. The hash resolves to a brief:public:{hash} → {userId, issueSlot} Redis pointer; if absent, the brief was never shared. Share pointers are written lazily (on share, not on compose).
Carousel (images for social)
GET /api/brief/carousel/{userId}/{issueSlot}/{page}.png
Server-rendered PNG page (page = 1..N) of the brief, intended for Telegram sendMediaGroup, Slack chat.postMessage, LinkedIn, etc.
- Rendered via
@resvg/resvg-js with the bundled Linux native binding.
Content-Type: image/png, 1080×1350 (4:5 portrait).
- Not gated — uses the HMAC’d path as the capability.
Ancillary
GET /api/story?date=YYYY-MM-DD
Public read-only “story view” (web reader) for a shared brief. SEO-friendly HTML response.
GET /api/og-story?date=YYYY-MM-DD
Open Graph preview image for /api/story. Returns image/png, cached aggressively.
POST /api/chat-analyst
Streaming chat endpoint for the “Ask the analyst” in-dashboard assistant. Takes a user prompt + recent-signal context; returns SSE tokens.
- Auth: Clerk JWT + PRO
- Streams:
text/event-stream
- Back-end:
intelligence/v1/chat-analyst-* handlers compose context + prompt
POST /api/widget-agent
Single-shot completion endpoint used by embedded widget iframes. Auth via X-WorldMonitor-Key (partner keys). Rate-limited per key.
