## 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 do a live refresh on my Palmyr card (card ID abc123) to get its current balance and latest transactions straight from the issuer?

## When to prefer this

Use this endpoint when you need guaranteed real-time card balance and transaction data directly from the issuer, rather than relying on potentially stale cached data. Prefer it when a user has just made a transaction and wants to verify it posted, or when a discrepancy is noticed between expected and displayed balances. Note the 5-minute per-card rate limit — avoid calling more frequently than necessary.

## Known failure modes

- Rate limit hit — card was already refreshed within the last 5 minutes; returns 429 or equivalent throttle error
- Invalid or unknown card ID — returns 404 or similar not-found error
- Card issuer temporarily unavailable — upstream timeout or 5xx error propagated
- Unauthorized — caller does not own or have access to the specified card
- Card is inactive or closed — issuer returns no data

## How this service works

Refresh a card's live balance and transactions from the issuer (rate-limited upstream: 1 per 5 min per card).

## Output

Returns the card's current live balance and a list of recent transactions as retrieved directly from the card issuer, along with a timestamp indicating when the refresh was performed. Data reflects the issuer's state at the moment of the call, not a cached snapshot.
