## 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-company-patent-list-dc86264a -d '<json body>'
```

Example prompt: Can you pull up the patent list for Apple — I want to see what patents they currently hold, including their titles and patent numbers?

## When to prefer this

Choose this endpoint when you need a structured, AI-agent-friendly list of patents by assignee name without setting up an API key. It is well-suited for quick competitive IP lookups, due diligence workflows, or enriching company profiles with patent data. Prefer it over USPTO or EPO direct queries when you want a simple pay-per-call interface with no authentication overhead and a machine-readable confidence score.

## Known failure modes

- Unknown or misspelled company name may return empty patent list or low confidence result
- Company name ambiguity (e.g. common names) may return patents for the wrong entity
- Data may be outdated if patents were filed or granted after the data_as_of date
- Unsupported company or jurisdiction may return supported:false
- Invalid request body (missing assignee field) returns a validation error
- Payment failure via x402/USDC may prevent the call from completing

## How this service works

Retrieves patents filed under the business name from the USPTO directory.

## Output

Returns a JSON object containing an array of patents, each with a title and patent number, along with a confidence rating (e.g. 'high'), a data freshness date (e.g. '2026-06'), any warnings, a supported flag, and a disclaimer that the data is informational only and should be verified with official sources or qualified professionals.
