## When to prefer this

Use this endpoint when a user needs a clear, plain-English explanation of a specific blockchain, DeFi, or onchain regulatory term. Ideal for decoding jargon encountered in smart contract documentation, DeFi protocols, or crypto regulatory filings. Prefer over general-purpose LLM knowledge when you need a curated, authoritative definition specifically scoped to onchain finance.

## Known failure modes

- Term not found in glossary — may return empty or 404 response
- Ambiguous term with multiple meanings in different contexts may return a generic definition
- Network or server error returns 5xx status
- Payment not processed correctly returns 402 Payment Required
