What we monitor

Claude API — Direct API access

Claude Console / Workbench — Dev dashboard

AWS Bedrock — Claude models — Alternate infrastructure

Google Vertex AI — Claude models — Alternate infrastructure

Message Batches API — Async

Model families

Claude Opus 4.6, Claude Opus 4.1Claude Sonnet 4.6, Claude Sonnet 4.5Claude Haiku 4.5Claude Sonnet 3.7 (deprecated)Model IDs differ across Claude API, Bedrock, and Vertex — verify per-platform

Common limits & quotas

Rate limits per tier; API returns real-time remaining quota via anthropic-ratelimit-* headers
Prompt caching reduces input token costs significantly for repeated contexts
Message Batches API offers ~50% cost reduction for async workloads

Ecosystem dependencies

Claude Code depends on Anthropic API + authCursor, Continue.dev route to Claude models by default for many usersEnterprise deployments often prefer Bedrock/Vertex for SLA and compliance

Operator notes

The anthropic-version header is required on every request — missing it returns a 400 that juniors often misdiagnose as an endpoint outage
Monitor anthropic-ratelimit-* headers proactively — don't wait for 429s
Prompt caching changes effective rate limits dramatically; measure with caching enabled
For high-volume prod: provision Bedrock or Vertex as a fallback route; it's a different infrastructure, often unaffected by direct API incidents

Fallback alternatives

What to use if this service is down

Direct Anthropic API is degraded

AWS Bedrock-hosted Claude can reduce downtime if your org is on AWS

Low cost if already provisioned

Easy switch

Anthropic and Bedrock both down

Google Vertex AI-hosted Claude is a third infrastructure path

Moderate effort

All Anthropic paths unavailable

OpenAI API or Google Gemini API can reduce downtime for general chat

Low cost with abstraction layer

Easy switch

Long-context workloads specifically

Gemini 2.5 Pro handles very long contexts

Easy switch

How we monitor

downforai.com probes each AI service every 2–5 minutes from multiple independent locations. We measure HTTP response codes, latency (p50 & p95), and endpoint availability across the surfaces listed above. Status is classified as Operational, Degraded, or Outage based on a weighted combination of probe results. Uptime is calculated over 30-minute buckets and the last 24 hours. User reports are factored into our diagnosis as a secondary signal. We are independent of all providers listed and receive no compensation to report any particular status.
