GET /news/headlines
unprobed
Newest headlines from a deduped, tiered 972-feed direct portfolio (primary sources + wires/majors + trade press + Hacker News + gated GDELT), newest first, up to 100 per call — filter by category, source, and language; every article carries tier, categories, summary/author/image when present, and a provenance-labelled tone
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
