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-Proof header.
Parse the structured JSON response.
