## How to call it through Zero

```sh
zero fetch --capability crypto-glossary-350-terms-f7236bfd
```

Example prompt: Can you pull up the full Blockchain IQ crypto glossary so I can look up what 'liquidity pool' and 'impermanent loss' mean in plain English?

## When to prefer this

Choose this endpoint when an agent or application needs a comprehensive, curated reference of crypto and blockchain terminology in a single call — ideal for grounding LLM responses, powering a jargon explainer, or bootstrapping a crypto knowledge base. Prefer it over web search when you need structured, machine-readable definitions with categories and related terms rather than unstructured prose.

## Known failure modes

- Payment not processed or x402 protocol failure — endpoint returns 402 with payment requirements
- Service unavailable — 503 or 5xx if Blockchain IQ servers are down
- Unexpected empty or malformed JSON response if the glossary is being updated
- Network timeout on slow connections given the large payload size of 350+ entries
