## 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 palmyr-cards-3ba1e37f
```

Example prompt: Can you pull up all my Palmyr prepaid cards and show me which ones are active along with their current balances?

## When to prefer this

Use this endpoint when you need a quick overview of all prepaid cards and their balances for an account. Prefer this over fetching individual cards (/cards/:id) when you don't yet know the specific card ID, or when you need to compare balances across multiple cards at once.

## Known failure modes

- Authentication failure — missing or invalid credentials returns 401
- No cards found — account has no prepaid cards, returns empty list
- Rate limit exceeded — too many requests in a short window
- Service unavailable — upstream card provider outage

## How this service works

List your prepaid cards (status, last4, balance — never full card numbers; those are per-card via GET /cards/:id).

## Output

A list of prepaid card summaries for the authenticated user, each including the card's current status (e.g. active, inactive), last 4 digits of the card number, and available balance. Full card numbers are not returned by this endpoint.
