P50 = typical speed. P95 = worst case 95% of the time. Measured by Tickerr's independent inference checks. Requires ≥10 checks to display.
TTFT over 24 hours
ⓘ Authenticated streaming API calls via native fetch. TTFT = milliseconds from request start to first streamed token chunk. Throughput = output tokens ÷ generation time. Checks run from Vercel us-east-1. Independent of the provider's official status page.

Claude API not working? Common error codes
If Claude's API is returning errors, the table below explains what each code means and how to fix it. If errors are widespread, check the live status above — a service incident will appear there within minutes.
| Error | What it means & what to do |
|---|---|
| HTTP 429 | Rate limit hit — check your plan tier, add exponential backoff |
| HTTP 529 (overload_error) | Anthropic is overloaded — retry after 30–60 seconds |
| HTTP 500 (api_error) | Unexpected server error — retry once, then check this page |
| HTTP 503 | Service unavailable — check for active incidents below |
Note: Tickerr monitors Claude's status endpoint, not individual API calls. An HTTP 429 or 500 in your app may be specific to your account tier — check the rate limits page for plan-specific thresholds.
About Claude status
Claude is Anthropic's AI assistant and API, available in Haiku, Sonnet, and Opus tiers. This page tracks two independent signals: HTTP availability (is Anthropic's infrastructure reachable?) and live API inference (is the Claude API actually working for developers?). Tickerr makes authenticated API calls to all six Claude models — claude-haiku-4-5, claude-haiku-3-5, claude-sonnet-4-6, claude-sonnet-4, claude-opus-4-6, and claude-opus-4 — every 5 minutes, measuring TTFT (time-to-first-token) and output throughput. This catches model-layer failures that don't show up as HTTP outages, covering roughly 35% of incidents. Common Claude API errors: HTTP 529 overloaded_error (Anthropic at capacity — retry after 30–60s), HTTP 429 rate_limit_error (you've hit plan limits — check the rate limits page), HTTP 500 api_error (unexpected server error — retry once). If the Claude API is not working or returning 529 overloaded responses, check the live status above — Tickerr typically detects these within 5 minutes. Claude API latency (TTFT) typically runs 300–800ms for Haiku models and 600ms–2s for Opus under normal load. Anthropic's official status page at status.anthropic.com is updated within 15–30 minutes of a confirmed incident; Tickerr's independent inference monitoring surfaces issues faster.
