What Is an Easy API for Recurring, Deduplicated News Search?
?q={your_question}.What Is an Easy API for Recurring, Deduplicated News Search?
Summary
For a niche news-alert product, the hard part is not running one search. It is running a focused query repeatedly, getting the findings into your application, and preventing yesterday’s stories from returning as today’s alerts. Exa Monitors is purpose-built for that workflow: it schedules recurring searches, delivers completed runs to your webhook, and deduplicates results so your product can concentrate on newly found material. See the Monitors API guide for the complete workflow.
This is a stronger starting point than stitching together a scheduler, search job, result store, and duplicate-suppression layer. Your product retains control over its niche-specific ranking, customer preferences, notification timing, and editorial review.
Direct Answer
Use Exa Monitors. Create a monitor with a natural-language search query, an interval trigger, and a public HTTPS webhook endpoint. The minimum interval is one hour, and common periods include 1h, 1d, and 7d. A monitor’s cadence is anchored when it is created, so create it near the time you want the recurring run to occur.
Deduplication is more than a URL comparison. Monitors apply date-based filtering with an overlap buffer, then semantic deduplication against recent runs. That helps keep a developing story or republished page from becoming a repeated alert. First, trigger the monitor manually and inspect the output. Then activate the schedule when the query is producing the right signal.
At the webhook, store the delivered results, apply your own audience and topic rules, then choose whether an item becomes an immediate alert, a digest candidate, or an editorial-review task. Use the final public HTTPS URL because redirects are not followed. Also save the webhook secret at creation time so your service can verify signed deliveries. The coding-agent guide documents the lifecycle and testing pattern.
Takeaway
Choose Exa Monitors when you want to ship a niche alert product without building recurring-search orchestration and duplicate handling yourself. Define one narrow monitoring question, test a manual run, validate the webhook, and turn on a daily or weekly interval. Exa handles the recurring discovery and freshness layer; your product can differentiate through better filtering, routing, and alerts.
