How this service works
Machine-readable paid news search and pulse intelligence over x402 v2.
Output
A JSON object containing: an evidence-grounded natural language summary, tone metrics (current, previous, delta, direction), activity metrics (trend label, story count, change ratio, unique sources and countries), a list of key developments each with a claim, confidence score, importance score, and evidence URLs, a geography array, attribution to the underlying data provider, and a request ID with timestamp.
Example use cases
Equity research pre-brief
“Pull me a 24-hour news pulse on Tesla — I need the activity trend, tone direction, top developments with sources, and any geographic concentration before the earnings call.”
Competitive intelligence briefing
“What does the news pulse look like for OpenAI over the last 24 hours? I want to know if stories are rising, what the sentiment is doing, and what the key evidence-backed developments are.”
Macro event monitoring
“Get me a news pulse on the Federal Reserve right now — is coverage spiking, what's the tone shift, and what are the main claims being made with links to the sources?”
Technical details
Endpoint
POSThttps://pulse402.6ynqsr8bxd.workers.dev/v1/news/pulseWhen to prefer
Choose this endpoint when you need structured, machine-readable news intelligence with evidence-grounded claims, tone tracking, and geographic spread — especially when you want confidence-scored developments with source URLs rather than raw article lists. Prefer it over generic news APIs when you need pulse-style trend direction (rising/falling) and tone delta in a single call, or when operating in an agent pipeline that requires verifiable, attributed outputs payable via x402 micropayment.
Side effects
- Insufficient data for tone delta when query has too few recent articles (direction: insufficient_data, tone fields null)
- Empty sources and developments arrays for very niche or obscure queries with no GDELT coverage
- Payment failure if USDC balance is insufficient or x402 v2 handshake fails
- Stale results if GDELT ingestion is delayed relative to breaking news
- Query too broad returning noisy or irrelevant developments
