## 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 ai-tech-glossary-pro-export-plain-language-definitions-api-08b724e2
```

Example prompt: Can you pull the full AI and tech glossary — I want plain-English definitions for terms like MCP, RAG, AI agents, GEO, tokens, and hallucinations, along with any concept comparisons and code examples?

## When to prefer this

Choose this endpoint when you need a comprehensive, pre-curated, human-readable glossary of AI and tech terminology in one call — especially for terms like MCP, RAG, GEO, x402, and llms.txt that are new enough to be poorly covered elsewhere. Prefer it over general-purpose LLM knowledge when you need sourced definitions, code examples, and concept comparisons in a structured JSON format ready for downstream use in docs, onboarding, or agent knowledge bases.

## Known failure modes

- Payment not made or insufficient USDC balance — 402 Payment Required response
- Network timeout on the export endpoint
- Malformed or empty JSON response if the glossary data is unavailable
- Rate limiting if called too frequently in a short window
