## How to call it through Zero

```sh
zero fetch --capability ishob-topic-content-retrieval-f9a4d7b3
```

Example prompt: Can you pull up the topic content for the slug 'crypto-risk-assessment' from ISHOB — I need the title, abstract, and canonical ID?

## When to prefer this

Choose this endpoint when you need structured topic metadata (title, abstract, canonical ID) for a specific ISHOB topic slug, especially when building AI agent workflows that reference or summarize ISHOB knowledge topics by identifier. Prefer this over generic web search when you need authoritative, structured output with a stable canonical_id for downstream linking or cataloging.

## Known failure modes

- Slug not found — returns 404 or empty result if the slug does not match any known topic
- Malformed slug input — invalid characters or format may cause a 400 error
- Payment failure — x402 payment of 0.5 USDC not completed results in 402 response
- Service unavailable — ISHOB hub temporarily down returns 5xx
- Empty abstract — some topics may have a title and canonical_id but a null or minimal abstract
