This is the only un-authenticated endpoint in the cofounder API. Anyone with the slug can read the latest sanitized entries. See Public Founder Diary capability for the full conceptual overview, sanitization rules, and how to enable it.

GET

Query params: Response:

What’s in the response

  • appName — public-friendly app name
  • headline — one-line summary
  • briefing — full markdown briefing with absolute dollars masked as $▒
  • metricsSummary — relative metrics only (deltas %, ASO score, conversion %)
  • publishedAt — when the entry was published (i.e., when the run completed)

What’s NOT in the response

  • Owner email
  • Integration credentials or details
  • Absolute dollar revenue / MRR / ARR (always masked)
  • API keys, webhooks, secrets
  • The underlying full report object (only the sanitized briefing is exposed)

Errors

  • 404 NOT_FOUND — slug doesn’t exist or has no public entries

Caching

The endpoint is read-only and deterministic per (slug, limit). Cache it freely on your side — entries are append-only so the same response is safe to cache for 5-10 minutes.
