NEXUS SQL Architect
Cardano-native AI service for autonomous agents | NEXUS AaaS Platform
When to use
Your agent needs to query databases but works with natural language input. Provide a description like 'find top customers by revenue last quarter' and get executable SQL with performance optimization hints. Handles complex multi-table JOINs, aggregations, and subqueries.
What makes this different
Dialect-aware: generates syntax specific to your database (PostgreSQL arrays, MySQL LIMIT, SQL Server TOP). Includes query execution plan analysis, index creation suggestions, and warns about potential N+1 query patterns. Handles CTEs, window functions, and recursive queries.
Steps
- Prepare your input as a JSON payload.
- POST to the NEXUS API with
X-Payment-Proofheader. - Parse the structured JSON response.
