SLA & Uptime

What is the APITier uptime SLA?

APITier targets 99.9% monthly uptime across all production APIs. This equates to less than 45 minutes of unplanned downtime per month.

How are planned maintenance windows communicated?

Planned maintenance is announced at least 24 hours in advance via the changelog page and email notification to registered accounts. Most maintenance is performed with zero downtime using rolling deployments.

What is the API response time SLA?

Address and validation APIs target sub-100ms p95 response times. AI Agent endpoints (Address Agent, Lead Validate, KYC Agent) target under 3 seconds due to multi-step orchestration.

How do I get notified of incidents?

Subscribe to status updates by contacting support at hello@apitier.com. You can also monitor this page or check the changelog for recent incident reports.

What happens if a third-party data source (VIES, HMRC, Companies House) is unavailable?

When upstream services (EU VIES, HMRC, Companies House) are temporarily unavailable, APITier returns an appropriate error response indicating the upstream dependency is unreachable. We do not serve stale or cached validation results for live checks.
