## How to call it through Zero

```sh
zero fetch --capability api-seneschal-space-4a0a8d9b
```

Example prompt: What's the current Monero block height and is the node fully synced?

## When to prefer this

Use this endpoint when you need a quick, authoritative, real-time Monero chain height and sync status from a dedicated monerod node, especially in automated workflows or monitoring systems that need a lightweight single-fact response without parsing a full block explorer.

## Known failure modes

- Node temporarily unreachable or being restarted — 503 or timeout
- Payment not provided or insufficient — 402 Payment Required
- Rate limit exceeded — 429 Too Many Requests
- Node behind on sync, returning stale height

## How this service works

Single-fact: current Monero chain height + sync status. Sourced from a live operator-run monerod node.

## Output

Returns a single-fact JSON response containing the current Monero blockchain height (block count) and sync status from a live Seneschal-operated monerod node.
