Enhanced AI-Powered Search: The DRep AI API uses advanced natural language processing to understand complex queries about Cardano’s Delegated Representatives, including their voting patterns, attributes, and governance participation.
The DRep AI API enables you to find DReps based on comprehensive criteria, including their attributes (voting power, delegators, participation rate, alignment scores) and their detailed voting behavior on specific proposals using natural language queries.

Request Headers

x-api-key
string
required
Your API key for authentication

Request Body

query
string
required
Natural language query describing the DReps you want to find. Supports complex queries with AND/OR logic, proposal-specific searches, and attribute-based filtering.Example queries:
  • "Find DReps with more than 100M ADA voting power"
  • "Show active DReps who voted yes on the Cardano NCL proposal"
  • "Find DReps who voted yes on treasury proposals and no on parameter changes"
  • "Show DReps registered in 2024 with high participation rates"

Advanced Features

Smart Caching: The API uses intelligent caching to speed up repeated queries. First-time complex queries may take 10-15 seconds, while cached queries return in under 2 seconds.
Query Performance: Complex queries involving multiple proposals or detailed vote pattern analysis may take 10-15 seconds on first execution. Subsequent identical queries will be much faster due to caching.
