Common failure patterns and how to diagnose them

Provider details

The Anthropic API provides programmatic access to Claude models via a REST interface at https://api.anthropic.com. Also available through AWS Bedrock and Google Vertex AI as separate infrastructures.

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
Status page segments
Claude APIClaude Consoleclaude.aiClaude Code
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

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

How we monitor

DownForAI checks monitored AI service surfaces on a rotating schedule, roughly every 75 minutes per surface, from a single centralized probe infrastructure. For services with an official machine-readable status page, we use that official status signal when available. For other services, we perform a basic public-surface check. Some services block datacenter probes; in those cases we mark them as “Monitoring limited” instead of treating a failed probe as a confirmed outage. Status is classified as Operational, Degraded, or Outage. Network latency (check response time) measures how long the monitored endpoint took to respond to our probe — it is not model inference speed, time-to-first-token, or tokens-per-second performance. We are independent of all providers listed and receive no compensation to report any particular status.
