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

Example prompt: Can you look up DeFi entity discovery for Aave — I want to know what StableJack's research API returns about it as a protocol, including its category and key metadata?

## When to prefer this

Use this endpoint when you need structured, agent-ready metadata about a specific DeFi protocol, vault, or platform and want a curated research data source rather than scraping raw blockchain data. It is best suited for protocol discovery, entity classification, and pre-trade or portfolio research workflows within the DeFi domain.

## Known failure modes

- Unknown or unsupported DeFi entity returns empty data or error
- Malformed request body causes validation error
- Payment failure (insufficient USDC balance) blocks the call
- Entity name ambiguity may return unexpected or multiple results
- API downtime or timeout returns non-OK response
