Errors

For error responses (400, 403, 422, etc.), see Handling Errors.

​
Using the struct field

The struct field controls which fields appear in the response’s structured_data. Each key becomes a field in structured_data, and its value tells the agent what to find. Only fields specified in struct are included in the response. You can pass either a plain-English description or an object with description and type: 
{
  "struct": {
    "suitability_score": "Overall qualification score (0-10)",
    "final_verdict": {"description": "Clear YES/NO decision", "type": "str"}
  }
}
The agent uses these descriptions to guide its evaluation. Be specific — "Overall qualification score from 0-10 based on weighted criteria" returns better results than "score". For supported types, type resolution priority, and casting examples, see Struct & Type Casting.

​
Parameters

​
qualification_criteria

Each criteria object requires:
  • criteria_name — Unique identifier for the criteria.
  • description — Detailed description of what to evaluate.
  • weight — Importance multiplier (higher = more important).
  • threshold — Optional minimum score requirement.
