🟡 P2: Verify SDK telemetry headers are working post-Kaggle launch

[karlwaldman]

After the Kaggle notebook launch, verify that the SDK telemetry headers we added are being captured in production.

Context:
We published:

• Python SDK v1.0.2 with telemetry headers (X-SDK-Language, X-SDK-Version, X-Client-Type)
• Node.js SDK v0.3.2 with same headers

What to Check (24-48 hours after Kaggle launch):

Query production database:

-- Check if SDK telemetry is being captured
SELECT 
  sdk_language,
  sdk_version,
  COUNT(*) as requests
FROM api_requests
WHERE created_at > NOW() - INTERVAL '24 hours'
  AND sdk_language IS NOT NULL
GROUP BY sdk_language, sdk_version
ORDER BY requests DESC;

-- Identify Kaggle traffic
SELECT 
  COUNT(*) as kaggle_requests,
  sdk_language,
  user_agent
FROM api_requests
WHERE created_at > NOW() - INTERVAL '24 hours'
  AND (
    user_agent LIKE '%kaggle%' 
    OR user_agent LIKE '%OilPriceAPI-Python%'
  )
GROUP BY sdk_language, user_agent;

Success Criteria:

• ✅ SDK telemetry headers appear in database
• ✅ Can distinguish SDK users from manual API calls
• ✅ Can identify Kaggle notebook traffic
• ✅ Download spike correlates with Kaggle views

Follow-up Actions:

• Track SDK adoption metrics weekly
• Create dashboard for SDK usage
• Identify power users for outreach
