## 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 assay-systems-the-extract-ottawa-government-market-0f312c55

Example prompt: Pull The Extract for Canada and show me the buyer-supplier pairs on page 1 — I want to see which government buyers are actively contracting with suppliers in my sector.

## When to prefer this

Choose this endpoint when you need company-level government market intelligence derived from Canada's public contract register, specifically for the Ottawa/federal market. Prefer this over general web search when you want pre-computed, structured data about buyer-supplier relationships, contract lock-ins, or active buyer lists — especially for B2G sales research or competitive intelligence on government contractors.

## Known failure modes

- Invalid or unsupported country code returns an error or empty data
- Invalid 'kind' enum value rejected at input validation
- No contracts found for the specified buyer/supplier combination returns empty data object
- Payment failure (402) if x402 micropayment is not properly handled
- Rate limiting or access denial if payment is not processed
