## How to call it through Zero

```sh
zero fetch --capability particle-pro-list-company-competitors-8e4ae114
```

Example prompt: Can you pull up a ranked list of Apple's top competitors — ranked by how much news coverage and market prominence they have? Use 'apple' as the company ID and show me the top 10.

## When to prefer this

Choose this endpoint when you need a ranked, multi-signal competitive landscape for a specific company — particularly when prominence ordering (news coverage + market cap + podcast + Wikidata) matters more than a raw alphabetical or category-only list. Prefer it over generic web searches when you need structured, paginated competitor data tied to a specific company identifier.

## Known failure modes

- Unknown company slug or domain returns a 404 or empty competitors list
- Invalid cursor value causes a pagination error
- Rate limiting or payment failure (x402) blocks the request
- Company with very low profile may return few or no competitors
- Malformed 'id' path parameter results in a 400 bad request

## How this service works

List company competitors. Returns a paginated list of competitors for a company, ordered by prominence (news coverage volume, market cap, podcast appearances, Wikidata notability) so the largest / most-newsworthy competitors come first.

## Output

A paginated list of competitor companies for the specified company, each ordered by a composite prominence score derived from news coverage volume, market capitalization, podcast appearances, and Wikidata notability. The response includes an opaque pagination cursor for fetching subsequent pages.
