Copied from the file, not written here

JSON Output Format for Data Retrieval

Output Structure

Every answer must follow this exact format:

{
    "q1": {"answer": ["item1", "item2"], "tokens": 123},
    "q2": {"answer": ["item1"], "tokens": 456},
    "q3": {"answer": ["url1", "url2"], "tokens": 789}
}

Rules

answer: Always a list, even if only 1 item
tokens: Positive numeric value (not a string)
Questions keys: Match question identifiers (q1, q2, q3, etc.)

Answer Formatting

Multiple Items (list with length > 1):

"answer": ["eid_abc123", "eid_def456", "eid_ghi789"]

Single Item (still in a list):

"answer": ["eid_abc123"]

Empty Results:

"answer": []

Token Counting

Track tokens consumed for each question:

Note the token count from API usage or elapsed processing
Store as positive integer in tokens field
Total tokens = sum of all question tokens

Python code to write output:

import json

results = {
    "q1": {"answer": ["eid_1e9356f5", "eid_06cddbb3"], "tokens": 150},
    "q2": {"answer": ["eid_99835861"], "tokens": 200},
    "q3": {"answer": ["https://example.com/demo"], "tokens": 100}
}

with open('/root/answer.json', 'w') as f:
    json.dump(results, f, indent=2)

Validation Checklist

All questions answered (q1, q2, q3, ...)
Each answer is a list
Single items still in list format
Token counts are positive integers
File saved to /root/answer.json
Valid JSON (test with jq or python -m json.tool)
