news.search

Live news search. Returns recent headlines with title, URL, snippet, publisher source, relative age, and a breaking-news flag — real-time coverage past any model training cutoff. Supports count (1-20), offset, country (2-letter), and freshness (pd=past day, pw=past week, pm=past month, py=past year). Use for current events, market-moving developments, monitoring, and "what happened with X" questions. For general web results see /api/search/web; for Hacker News specifically see /api/news/hn-top.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/news/search?q=example&count=10&offset=0&country=example&freshness=pd'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/news/search?q=example&count=10&offset=0&country=example&freshness=pd' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/news/search?q=example&count=10&offset=0&country=example&freshness=pd'
