OpenRouter's /api/v1/models endpoint is the source of truth for model availability. Models can be temporarily unavailable, have degraded performance, or be permanently removed. This skill covers querying model status, building health probes, tracking availability over time, and automating failover.

| Error | Cause | Fix |
|---|---|---|
| Model not in catalog | Model renamed or removed | Use find_similar() to find replacement |
| Health check timeout (>15s) | Model overloaded or cold-starting | Distinguish slow vs down; increase timeout for probes |
| False positive down | Transient network issue | Require 2-3 consecutive failures before alerting |
| 402 on health check | Credits exhausted | Health checks cost ~$0.0001 each; ensure adequate credits |
