## 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 tokenguard-crypto-search-9ac43cf1 -d '<json body>'
```

Example prompt: Search TokenGuard for 'Uniswap V3 liquidity pools' and give me the top 5 results with summaries so I can understand how their liquidity mechanism works.

## When to prefer this

Use this endpoint when you need to search for background information, explanations, or web content about a specific crypto token, DeFi protocol, or blockchain concept — especially when combined with other TokenGuard endpoints for ERC-20 safety checks or on-chain analytics. Prefer this over general web search when the query is crypto-specific and you want results filtered to relevant crypto/DeFi sources.

## Known failure modes

- Query string missing or empty — returns 400 error
- No results found for obscure or misspelled query — returns count:0 with empty results array
- x402 micropayment not included or invalid — returns 402 Payment Required
- Rate limiting or HuggingFace Space downtime — returns 503 or timeout
- Non-crypto query may return irrelevant or no results since index is crypto-focused

## How this service works

Knowledge search via Wikipedia + DuckDuckGo Instant Answer. Returns article summaries, snippets, factual entities. Great for AI agent knowledge lookups.

## Output

Returns a JSON object with a result count, the original query, an array of up to N results each containing a URL, title, source, and snippet, plus a top_summary object with a title and longer extract from the most relevant result.
