## How to call it through Zero

```sh
zero fetch --capability canadabuys-open-tender-notices-bd61cbff
```

Example prompt: Can you find the latest open Canadian government tenders related to 'construction' on CanadaBuys — show me up to 10 results with their closing dates and procurement methods?

## When to prefer this

Use this endpoint when you need to discover or monitor open Canadian federal government procurement opportunities, particularly when filtering by keyword. It is best suited for agents doing procurement intelligence, supplier sourcing, or contract monitoring against the Government of Canada's official CanadaBuys open data feed. Prefer this over manual CSV downloads or scraping CanadaBuys directly.

## Known failure modes

- No results returned if keyword matches no open notices
- Query too short (under 3 chars) or too long (over 60 chars) returns validation error
- Limit out of range (must be 1–10) returns error
- CanadaBuys source CSV temporarily unavailable causes fetch failure
- Stale results if CanadaBuys has not yet refreshed the CSV

## How this service works
