## 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 us-company-search-6fecce75
```

Example prompt: Can you look up the SEC registrant name and CIK for Nvidia so I can pull its filings?

## When to prefer this

Use this endpoint when you need to resolve a company name or ticker to its official SEC CIK and registrant name before calling other SEC EDGAR-based tools. Prefer it over generic search engines when you need exact, structured identifiers for US-listed companies rather than web results or financial data.

## Known failure modes

- No matches found for obscure or misspelled company names
- Ambiguous queries may return many loosely related results
- Non-US or OTC-only companies may not appear
- Rate limiting or service unavailability from the hosted provider
- Limit parameter out of range (must be 1-50)

## How this service works

Find US-listed companies by name or ticker (e.g. 'nvidia', 'bank of america', 'TSLA'): ticker, exact SEC registrant name and CIK, best matches first. Use to resolve a company name before calling other SEC tools.

## Output

A ranked list of matching US-listed companies, each with their ticker symbol, official SEC registrant name, and CIK number — ordered by relevance to the search query.
