Provider status guide
Is OpenRouter down?
Check official OpenRouter status and troubleshoot common API errors before blaming your code, key, quota, model name, network, or the provider.
Common errors
What usually breaks
401
Invalid or missing API key
Authentication failed before the request reached the model.
402
Insufficient credits
The account or routed provider does not have enough credits to complete the request.
403
Permission denied
The key is recognized but not allowed to use this model, endpoint, region, or project.
429
Rate limit or quota exceeded
Your request rate, token throughput, or quota exceeded the provider's limit.
502
Upstream provider error
A gateway or routing provider could not get a valid response from the model backend.
503
Unavailable
The service or model is temporarily unavailable.
Troubleshooting checklist
Before calling it a OpenRouter outage
- Check the official provider status page.
- Confirm your API key is valid and belongs to the right project.
- Confirm your account has credits, quota, and model access.
- Confirm the model name and endpoint path are correct.
- Retry with exponential backoff instead of immediate loops.
- Test with cURL outside your app.
- Try another model or provider if production is impacted.
- Enable fallback routing before the next incident.
Decision tree
Official status is green, but my OpenRouter API still fails
- Run a minimal cURL command with the same key and model outside your app.
- If cURL fails with 401 or 403, check key scope, project, account access, and model permissions.
- If cURL returns 429, check quota, billing, token-per-minute limits, and concurrency.
- If only browser requests fail, treat it as CORS or preflight until cURL proves otherwise.
- If one model fails but another works, check model availability or fallback routing.
- If production fails but local works, compare environment variables, outbound network rules, and region.
FAQ
OpenRouter API status questions
Is OpenRouter down right now?
LLMPing links to the official OpenRouter status source and shows troubleshooting guidance. If live fetch is unavailable, use the official status page for the latest provider-owned incident data.
How do I check OpenRouter API status?
Start with the official status page, then run a minimal cURL request outside your app to separate provider issues from key, quota, model, network, or code issues.
Why is my OpenRouter API request failing?
Common causes include invalid API keys, missing model access, rate limits, quota, wrong endpoint path, CORS, provider incidents, or upstream model capacity.
What should I do if OpenRouter returns 429?
Check billing and quota, reduce concurrency, add exponential backoff with jitter, lower token usage, and route urgent production traffic to a fallback model or provider.
