# Canada Open Data Catalogue Search

> Canada Open Data Catalogue Search is a paid API for AI agents from api.companyrecords-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Searches the Canadian federal open data catalogue (open.canada.ca) for datasets matching a keyword, returning catalogue metadata such as title, publisher, licence, last modified date, resource count, and dataset link.

## 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 canada-open-data-catalogue-search-5e3b145c
```

Example prompt: Search the Canadian federal open data catalogue for up to 8 datasets about 'climate change' and give me their titles, publishers, licences, and links.

## When to prefer this

Choose this endpoint when you need to discover or enumerate Canadian federal government datasets by topic, and only need catalogue-level metadata (title, publisher, licence, freshness, link) rather than the actual dataset contents. Prefer this over general web search when you specifically want open.canada.ca datasets with structured, machine-readable metadata. Not suitable for retrieving the underlying data files or for searching provincial/municipal Canadian datasets.

## Known failure modes

- Query string shorter than 2 or longer than 80 characters returns a validation error
- No matching datasets found returns an empty results list
- CKAN API upstream outage may cause timeout or 5xx error
- Rows parameter outside 1–10 range may be rejected or clamped
- Non-English or non-French search terms may yield fewer results

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a list of up to 10 (default 5) dataset catalogue entries from the Canadian federal open data portal, each including: dataset title, publisher name, licence type, last modified date, number of resources, and a direct link to the dataset page on open.canada.ca. This is catalogue metadata only — not the actual data files themselves.
