#### Merchant Identifier Search -- AI Powered endpoint that understands intent, not just inputs {#merchant-identifier-search--ai-powered-endpoint-that-understands-intent-not-just-inputs}

Introducing the new **Merchant Search API endpoint**, built to transform how clients match and resolve merchant data.
Powered by advanced AI, this endpoint goes beyond traditional matching to interpret context, infer intent, and deliver precise results even when the input isn't perfect.
It leverages AI-powered entity recognition, semantic reasoning, and multi-signal matching to intelligently process client inputs and return highly accurate matches across complex, real-world scenarios.
