## 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 bizintel-api-opencorporates-company-lookup-24eb350f -d '<json body>'
```

Example prompt: Can you look up the official corporate registration number for Stripe, Inc. in the OpenCorporates registry?

## When to prefer this

Use this endpoint when you need to retrieve official corporate registration numbers and legal entity names from the OpenCorporates global registry. Prefer this over general web search when you need structured, registry-sourced data with a confidence score and freshness date. Best for due diligence, B2B enrichment, or verifying a company's legal existence without needing to manage API keys.

## Known failure modes

- Company not found in OpenCorporates registry — returns found: false with empty companies array
- Ambiguous company name matching multiple entities — returns multiple results requiring disambiguation
- Registry temporarily unsupported — returns supported: false
- Payment failure over x402/USDC — request rejected before processing
- Rate or network timeout on the workers.dev edge node

## How this service works

Searches corporate entities in open directories to resolve active corporate status and jurisdiction.

## Output

Returns a JSON object with a 'found' boolean, a list of matching companies each containing their official name and company number, a confidence level (e.g. 'high'), a data freshness date (e.g. '2026-06'), any warnings, and a disclaimer about the informational nature of the data.
