How this service works
Search for data visualizations using natural language. Ask any question about finance, economics, demographics, sports, politics, climate, or health and get back interactive knowledge cards with charts, data, and source attribution. Example: {"inputs": {"text": "NVIDIA vs AMD revenue since 2018"}}. Returns cards with title, chart image URL, interactive webpage URL, embeddable URL, data description, and source information.
Output
Returns one or more knowledge cards, each containing: a title, a chart image URL (optionally in dark mode), an interactive webpage URL, an embeddable iframe URL, a textual description of the data, and source attribution (e.g. S&P Global, World Bank). Cards cover the queried topic with visual and contextual data.
Example use cases
Competitor revenue comparison chart
“Show me an interactive chart comparing Apple, Microsoft, and Google annual revenue from 2015 to 2024 — use curated financial data sources and balanced search depth.”
Climate trend visualization for a report
“I need a knowledge card showing global average temperature rise since 1990 by region — pull from curated climate data and give me the embeddable URL so I can drop it in my presentation.”
Sports performance stats over time
“Can you find a chart showing NBA scoring averages by team over the last 10 seasons? Use deep research mode to make sure I'm getting solid data.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/tako/v1/knowledge_searchWhen to prefer
Choose this endpoint when you need pre-built, sourced data visualizations for finance, economics, demographics, sports, politics, climate, or health — especially when you want an embeddable or shareable chart without building one from scratch. Prefer this over raw data APIs when the goal is a ready-to-display knowledge card with source attribution. Use the 'tako' source index for curated financial/economic data from S&P Global and World Bank; switch to 'web' or 'tako_deep_v2' for broader or deeper research.
Side effects
- Query is too ambiguous or unsupported topic — returns empty card set or low-relevance results
- Requested data not available in selected source_indexes — try adding 'web' or 'tako_deep_v2' to source_indexes
- Rate limit or payment failure via x402 — returns 402 Payment Required
- Invalid locale or country_code values — may default to en-US/US silently
- Deep search effort on niche queries may time out or return slowly
