## 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 a2a-nexus-canadabuys-tender-data-84f3ad73
```

Example prompt: Can you pull the current IT tender listings from CanadaBuys and show me what Canadian government procurement opportunities are open right now?

## When to prefer this

Use this endpoint when you need programmatic access to Canadian federal government IT procurement data from CanadaBuys, especially in agentic workflows that require x402 micropayment-compatible APIs. Prefer this over manual CanadaBuys portal browsing when building automated tender monitoring, procurement intelligence pipelines, or vendor alert systems focused on the Canadian public sector IT market.

## Known failure modes

- Upstream CanadaBuys platform unavailability causing empty or stale results
- Rate limiting or payment failure returning 402 status
- Tender list may be empty if no active IT tenders are currently posted
- Schema changes on CanadaBuys side may affect tender object structure
- Network timeout from the postulated.store proxy layer
