## 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-79a5eefe -d '<json body>'
```

Example prompt: Search FullEnrich for up to 10 software development companies headquartered in New York with between 50 and 500 employees — I need their legal names and headcount for a prospecting list.

## When to prefer this

Use this endpoint when you need to discover or look up companies by name, industry, headcount, or headquarters — especially for B2B sales prospecting, market research, or resolving brand names to legal entity names. Prefer this over generic web search when you need structured, filterable company data rather than unstructured text results. Best when you know the industry classification in LinkedIn taxonomy terms (Software Development, Research Services) rather than casual labels like SaaS or AI.

## Known failure modes

- 400 error if only limit/page is provided without names, industries, or headquarters_locations filters
- 400 error if filter values are not provided as [{value: '...'}] objects
- No results returned if brand name used instead of legal name (e.g. Cursor instead of Anysphere)
- Incorrect industry category if common terms like SaaS or AI are used instead of LinkedIn-style classifications like Software Development or Research Services
- Pagination failure if search_after token from a previous response is not passed correctly

## How this service works

FullEnrich Company Search — by name, industry, headcount, HQ. Requires names, industries, or headquarters_locations as [{ value: "..." }] (plain strings coerced); limit/page alone → 400. Paginate via search_after. Legal names not brands (Anysphere≠Cursor). Software Development not SaaS; Research Services not AI.

## Output

Returns a list of structured company profiles including legal company names, industry classifications, headcount ranges, and headquarters locations. Also returns a search_after token for paginating through additional results.
