## 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 fullenrich-company-search-183a3fbd -d '<json body>'
```

Example prompt: Search FullEnrich for software development companies headquartered in San Francisco with between 50 and 500 employees — give me the first 10 results with their legal names and domains.

## When to prefer this

Use this endpoint when you need to search or discover companies by firmographic attributes such as industry, headcount, or HQ location, especially when building lead lists, doing market research, or resolving brand names to legal entity names. Prefer this over contact enrichment endpoints when the goal is company-level discovery rather than individual person data.

## Known failure modes

- 400 error if only limit/page is provided without names, industries, or headquarters_locations
- Incorrect results if brand names (e.g. Cursor) are used instead of legal names (e.g. Anysphere)
- Wrong industry classification if SaaS is used instead of Software Development, or AI is used instead of Research Services
- Empty results if exact_match is used on a domain mismatch (e.g. searching ElevenLabs by brand instead of domain)
- Pagination may not work with page parameter on cached results — must use search_after cursor

## How this service works

FullEnrich Company Search — by name, industry, headcount, HQ. Requires names, industries, or headquarters_locations; limit/page alone → 400. Paginate via search_after (page ignored on cache). Legal names not brands (Anysphere≠Cursor). Software Development not SaaS; Research Services not AI. exact_match string-only — check domain for ElevenLabs, Runway.

## Output

Returns a list of company records matching the search criteria, each containing the legal company name, industry classification, employee headcount range, headquarters location, and company domain. Also includes a search_after cursor for paginating through large result sets.
