The Bing News Search API returns a list of world news from a search query which can be filtered by local news, topic, and searchable metadata. Results include information such as authoritative images, related news, and provider. This API provides a list of news similar to the "Bing.com/News" site, but the experience is not exact. Currently, a free plan that limits calls to 1000 transactions per month is available. The News Search API uses JSON format for data exchange, and API Keys for authentication.
