## 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 xrpl-account-preflight-check-f2e4af5b
```

Example prompt: Before I send XRP to rN7n3473SaZBCG4dFL83w7PV3xKGMo9osk, can you check if that address exists on the XRP Ledger and is able to receive payments?

## When to prefer this

Use this endpoint when you need a lightweight, fast preflight check before initiating an XRP Ledger payment to confirm the destination address is valid, funded (above reserve), and capable of receiving funds — especially useful before committing to a transaction that would fail on-chain. Prefer this over full XRPL node queries when you need a simple boolean answer without parsing raw ledger responses.

## Known failure modes

- Missing required 'address' query parameter returns an error
- Invalid or malformed XRP address format may return exists: false or an error
- Network connectivity issues to XRPL nodes may cause timeouts
- Issuer address provided without a currency code may yield incomplete results
- Payment required (x402) not fulfilled causes 402 response before any data is returned

## Output

A JSON object with at minimum an 'exists' boolean indicating whether the XRPL address is found on the ledger, and a 'can_receive' boolean indicating whether the account is capable of receiving payments. May include additional metadata about trustlines or destination tag requirements depending on the query.
