Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 quicknode-7e3edfeb -d '<json body>'
```

Example prompt: Call the Stellar mainnet RPC to get the latest ledger sequence number using the getLedgers method with no params.

## When to prefer this

Use this endpoint when you need reliable, low-latency access to the Stellar mainnet blockchain via a managed QuickNode node, especially when you need to query ledger state, account balances, transaction history, or broadcast transactions to the live Stellar network. Prefer this over running your own node or using free public endpoints when uptime and performance matter.
