Otto AI · Crypto News
x402.ottoai.services
Importance-ranked crypto headlines with per-article source links and publish times, plus a sentiment-scored market brief. Regenerated hourly; meta carries the snapshot's age and a fresh/stale verdict.
Otto AI · Equity News
x402.ottoai.services
Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary. Only articles that name the company are served — labelled `primary` when the headline names it, `mentioned` when only the summary does — so a symbol-tagged story about another company never fills the list. Redirect URLs withheld; no sentiment is fabricated.
