## 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 payai-entity-search-company-name-disambiguation-e57a744f
```

Example prompt: Can you search for 'Tesla' as a US company and give me its SEC CIK, LEI, Wikidata QID, and ticker — show me the top 3 ranked matches?

## When to prefer this

Use this endpoint as a cheap first step when you have only a company name and need to identify its official cross-reference IDs (LEI, CIK, QID, ticker) before calling a more expensive full entity resolution API. Prefer this when disambiguating between similarly named companies, filtering by country, or when you need to map a fuzzy human-typed name to a canonical legal entity identifier.

## Known failure modes

- No candidates found for obscure or misspelled company names
- Ambiguous names return many low-confidence candidates requiring further filtering
- Country filter may exclude valid matches if the wrong country code is provided
- Rate limiting or payment failure resulting in HTTP 402
- Names with special characters or abbreviations may reduce match quality

## How this service works

Disambiguate a company by name: fuzzy legal-name search returning ranked candidates, each with the ids known for it (Wikidata QID, GLEIF LEI, SEC CIK, ticker), country and a match score. Cheaper first step before entity/resolve.

## Output

A ranked list of up to 10 candidate companies matching the queried name, each with cross-referenced identifiers (Wikidata QID, GLEIF LEI, SEC CIK, stock ticker), the company's country, and a numerical match confidence score. This is a lightweight disambiguation step intended to precede full entity resolution.
