## 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-supplier-government-contracts-ottawa-437bbe95
```

Example prompt: Pull up the government contracting history for supplier CA-12345 in Canada — show me page 1 and filter to contracts that ended before 2024-01-01.

## When to prefer this

Use this endpoint when you need structured, paginated government contracting history for a specific supplier in a given country, sourced from the public contract register. Ideal for B2G market intelligence, vendor due diligence, competitive research, and procurement analytics. Prefer this over general web search when you need clean, computable contract data keyed to a supplier ID.

## Known failure modes

- Invalid or unknown supplier ID returns empty data or 404
- Unsupported country code returns an error
- Invalid date format for ends_before causes a 400 error
- Page number out of range returns empty results
- Payment failure (x402) prevents access to the endpoint
