## 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 fda-drug-approval-status-lookup-4f5740bc
```

Example prompt: Can you pull up the FDA approval details for drug application NDA212345 — I need to see the stored entity record for it.

## When to prefer this

Use this endpoint when you already have a specific FDA application entityId (e.g. 'fda-app:NDA212345') and need to retrieve its full stored detail record. Prefer this over broader search endpoints when you need a single, precise application lookup rather than a list or trend analysis.

## Known failure modes

- Missing or invalid entityId returns empty or error response
- entityId not found if the application is not yet tracked
- Malformed entityId format (not matching 'fda-app:NDA######') may return no result
- Payment not processed results in 402 response
- Rate limiting or service unavailability returns 5xx error

## How this service works

Stored detail for a single application (entityId like 'fda-app:NDA212345').

## Output

Returns a JSON object containing the stored detail entity for the specified FDA drug application, including approval status and associated metadata fields for the given NDA or BLA application ID.
