Tips

Knowledge Search is the main endpoint — start here for any data question
Use image_url to display charts in Slack, Discord, or other channels
embed_url gives an interactive iframe for web pages
Call List Default Schemas before Create Card to see available chart types
Set search_effort: "deep" for complex multi-metric comparisons
Data coverage: stock prices, revenue, GDP, unemployment, population, sports stats, weather, health, and more

Error Handling

400 - Invalid body or missing required fields
401 - Invalid API key
404 - Card not found (Chart Insights) or no results found (Knowledge Search)
Empty knowledge_cards array — try rephrasing or using source_indexes: ["tako", "web"]
