## 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 mti-knowledge-search-vietnam-trade-natural-farming-guides-b76f2144
```

Example prompt: Search the MTI Vietnam trade and farming knowledge base for 'organic rice export certification requirements' and give me up to 3 excerpts in English with their source links.

## When to prefer this

Choose this endpoint when you need curated, domain-specific knowledge about Vietnam trade regulations or natural/organic farming practices from a vetted 11-guide corpus. Prefer this over general web search when you need reliable sourced excerpts with direct guide links rather than broad internet results, or when working specifically in Vietnamese or English within the Mekong/Vietnam agricultural trade domain.

## Known failure modes

- Missing required 'query' parameter returns an error
- Query exceeding 300 characters may be rejected
- No matching results found returns an empty excerpts array
- Invalid 'lang' value (not 'en' or 'vi') may cause unexpected results
- 'limit' outside 1–3 range may be clamped or rejected
- Payment failure (x402) results in 402 response before search executes
