{
  "service": "up",
  "mercury_latest_ledger": 62458843,
  "stellar_latest_ledger": 62458843
}

Field	Description
service	"up" if all systems are operational, "down" if any component is degraded
mercury_latest_ledger	The latest ledger Mercury has indexed
stellar_latest_ledger	The current Stellar network tip (from Horizon)

If mercury_latest_ledger is significantly behind stellar_latest_ledger, Mercury is catching up. Both fields may be absent if unavailable.

Live status updates

Mercury posts live status updates to the public live-status Discord channel. You'll see a message whenever:

• The service/API goes down or comes back online

• Ingestion falls behind the Stellar network tip and later catches back up
