Agentic AI Over Custom API Data

HardPython

Problem

Design an agentic AI system with a custom API data endpoint and custom database implementation to process data and present the user a query interface to ask questions about the processed data from the API data source.

Implement the deterministic query core as query_api_data(records, queries). Each record is a dictionary with an integer id; queries use field=value, field~term, AND, OR, parentheses, optional SORT field ASC|DESC, and optional LIMIT n. Return matching record IDs for each query, using indexes rather than scanning every record for each request.

Constraints

  • 1 <= records.length <= 5000
  • 1 <= queries.length <= 1000
  • Every record contains a unique integer id
  • Record values are strings, integers, or lists of strings
  • Query parentheses are balanced and operators are uppercase or lowercase
  • A query contains at least one field=value or field~term expression

Function Signature
