Is Twelve Data down?

No — the Twelve Data API is operational. Our last check succeeded in 86ms.

APIzone continuously probes a public Twelve Data API endpoint from its own independent infrastructure and records response status and latency. Status is derived from consecutive failures and latency deviation — not from Twelve Data's own status page — so it reflects what we independently observe.

Degraded means the Twelve Data API is reachable but not fully healthy: some recent checks are failing, or response times are far above the normal baseline. It's a warning state between fully operational and down.

Over the last 90 days, APIzone has measured 99.93% uptime for the Twelve Data API. See the uptime breakdown above for 24-hour, 7-day, 30-day, and 90-day figures.
