Individual API providers have outages. AgentKey insulates your agent from them: when a provider becomes unavailable, AgentKey automatically routes to a backup that serves the same capability — with no interruption and nothing for you to do.

How routing works

AGENTKEY ROUTER
  ├─ Tavily      ✓ Active     → routing here
  ├─ Brave       ✕ Down       → skipped
  └─ Perplexity  ◦ Standby    → ready to take over
Within a capability (for example, web search), AgentKey keeps multiple providers behind the same interface. If the active one fails, the next healthy provider takes over transparently.

​
What this means for you

  • No code changes — failover happens at the routing layer.
  • One stable interface — you call a capability, not a specific vendor.
  • Higher uptime — a single provider’s outage no longer breaks your agent.
