Particle Pro Story Search

Choose this endpoint when you need to search across news stories using both keyword relevance and semantic meaning — particularly useful for political, legislative, and current events research where you want ranked, multi-publisher coverage. Prefer this over a pure keyword search when the query is conceptual or when you need semantically related articles beyond exact keyword matches.

• Empty result set if query is too niche or no matching stories exist
• Ambiguous queries may return loosely related stories
• Rate limiting or payment failures if USDC balance is insufficient
• Query string missing or malformed returns an error
• Overly broad queries may return low-relevance results
