How this service works
Machine-readable paid news search and pulse intelligence over x402 v2.
Output
A JSON object containing the search query, time window, and a list of news article results. Each result includes the article URL, title, publication timestamp, source domain, source name, language, country, and tone (when available). Also includes a result count, request ID, an as_of timestamp, and attribution to the underlying provider (GDELT Project).
Example use cases
Real-time earnings coverage tracker
“Search for all news articles mentioning 'Apple earnings' from the last 24 hours and summarize the headlines and their tones — I want to know if coverage is positive or negative.”
Competitor brand monitoring
“Find recent news articles about Tesla over the past day, including which countries and languages they're in, so I can see how international press is covering them.”
Breaking geopolitical event lookup
“Pull the latest news results about the Taiwan Strait from the past 24 hours — I need the article titles, source domains, and publication times.”
Technical details
Endpoint
POSThttps://pulse402.6ynqsr8bxd.workers.dev/v1/news/searchWhen to prefer
Choose this endpoint when you need machine-readable, structured news search results with source metadata (domain, language, country, tone) suitable for AI agent pipelines, and when you want micropayment-based access without API key subscription overhead. Prefer it over traditional news APIs when you need GDELT-backed global coverage or when operating in an x402 payment environment. It is especially useful for agents that need to search news on demand without committing to a subscription tier.
Side effects
- Payment not processed or x402 handshake fails — request is rejected before search executes
- Query returns zero results if the topic has no indexed coverage in the requested time window
- Tone and country fields may be null for many results depending on GDELT data availability
- Invalid or missing query parameter causes a 400-level error
- Time window parameter not recognized — defaults or errors depending on implementation
- Service unavailability on the Cloudflare Workers host returns 5xx errors
