## 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`):

Example prompt: Can you pull up US court cases and dockets that name Tesla Inc as a party? Give me up to 15 results across opinions and dockets so I can review their litigation exposure.

## When to prefer this

Use this endpoint when you need structured, normalized US court case data for a specific business entity for due diligence, compliance research, or litigation risk assessment. Prefer over general web search when you need structured docket numbers, citations, and court metadata from an authoritative public-domain source like CourtListener.

## Known failure modes

- No results found for an obscure or misspelled entity name
- Ambiguous entity name returns unrelated cases — use CIK or QID hint to narrow
- Exceeding limit parameter maximum of 25 returns a validation error
- Invalid record type enum value returns a 400 error
- Rate limit or payment failure returns 402 or 429 status
