## 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 agents-pubrio-com-pubrio-similar-company-search-4ce14585 -d '<json body>'
```

Example prompt: Can you find companies similar to Stripe using their domain stripe.com, filtered to fintech and AI keywords, and show me the first page of results?

## When to prefer this

Use this endpoint when you need to discover companies that are similar or analogous to a known reference company — ideal for competitive intelligence, sales prospecting, investor research, or market mapping. Prefer it over general company search when you have a specific anchor company and want ranked lookalikes with similarity scores rather than keyword-driven results.

## Known failure modes

- HTTP 416 if page or per_page exceeds subscription limits (max_search_page or max_search_per_page)
- Error if more than one singular identifier is supplied simultaneously
- Invalid or unresolvable domain/URL returns no results or an error
- Expired or insufficient credits result in an authorization or payment error
- Malformed URL inputs may be auto-converted or rejected depending on format

## How this service works

Find companies similar to a reference company. Supply exactly one singular identifier (`domain_search_id`, `domain`, `linkedin_url` or another `*_url`). Each row carries a `similarity_score` between 0 and 1.

## Output

An array of company objects each containing profile data and a similarity_score between 0 and 1 indicating how closely each company resembles the reference, along with metadata including echoed filters, request parameters, and per-call credit usage (credit, topup_credit, total_credit_cost).
