## How to call it through Zero

```sh

Example prompt: Before I start querying Tako, can you show me all the data topics and indexes it supports — like what finance, health, or sports metrics I can search across?

## When to prefer this

Use this endpoint before issuing Tako search queries to understand what data topics and indexes are available. Ideal for agents that need to validate whether a particular domain (e.g. health, sports, climate) is searchable before committing to a query. Prefer this over guessing index names or querying blindly.

## Known failure modes

- Invalid index_ids parameter returns error or empty results
- Service unavailable returns HTTP 5xx
- Payment failure (x402) blocks access if USDC not provided
- Specific index_id not found returns empty or partial response
