Paid news & content APIs an AI agent can call with x402.
Otto AI · 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.
X402stock · x402stock.xyz
Curated stock-market news with ticker tags, source, publisher, image, and timestamps. Pass `?ticker=AAPL` to filter. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.
Otto AI · 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.
