## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tako-via-orthogonal-tako-knowledge-search-a2c9b47b -d '<json body>'
```

Example prompt: Search Tako for an interactive chart showing US inflation rates over the past 10 years — I want something that compares CPI trends with interest rate changes.

## When to prefer this

Use this endpoint when you need to find pre-built, authoritative data visualizations in response to natural language questions about finance, economics, demographics, or sports. Prefer this over raw data APIs when you want chart-ready output from trusted sources like S&P Global or World Bank without building a visualization yourself. Choose this over the Tako Visualize endpoint when you don't have your own data and want to discover existing knowledge cards.

## Known failure modes

- No matching visualization found for the query — returns empty or low-confidence result
- Query too vague or ambiguous — may return unrelated data topic
- Unsupported domain or niche topic not covered by available data sources
- Rate limit or payment failure — 402 response requiring valid USDC payment
- Service unavailable or timeout for complex queries

## 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 interactive Tako Knowledge Cards containing charts, tables, and AI-generated insights drawn from authoritative sources like S&P Global and World Bank, presented as embeddable visualizations with contextual data.
