## 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 legal-memoryapi-org-09d89fd6
```

Example prompt: Can you pull up the full case details for the federal lawsuit Goldman Sachs v. SEC, docket number 1:23-cv-09170, from the Southern District of New York?

## When to prefer this

Use this endpoint when you already know a specific case ID, docket number, or precise case name and need full details about that single case. Prefer this over the search/company-lookup sibling endpoints when you have a specific identifier rather than needing to discover cases. Best for retrieving structured docket metadata for a known federal proceeding.

## Known failure modes

- Case ID or name not found — returns 404 or empty result
- Ambiguous case name matches multiple records — may return unexpected case
- Case exists in state court (not federal) — not covered by this endpoint
- Payment failure (x402 protocol) — call blocked if USDC payment not processed
- Invalid docket format — malformed ID returns error
