Does Metrion add latency to my requests?
Does Metrion add latency to my requests?
Yes, a small amount. Metrion is hosted in EU West (Ireland), so there is an additional network hop between your application and the AI provider. In practice, the overhead is typically a few milliseconds and is negligible compared to the provider’s own response time.You can see the actual end-to-end latency for every request on the Logs page and in the Latency tab of your dashboard.
Is my provider API key secure?
Is my provider API key secure?
Yes. In stored mode, your key is encrypted at rest. The encryption key is stored separately from the database, so your key material is never accessible in plain text. Metrion never logs or exposes key values anywhere in the application.In pass-through mode, your key is forwarded directly to the provider on each request and is never stored by Metrion.
Does Metrion work with streaming?
Does Metrion work with streaming?
Yes. Streaming (
stream: true) works for all supported providers. Pass it in your request body exactly as you would with the provider’s API directly — no additional configuration is needed on your end.What happens if I hit the Free plan limit?
What happens if I hit the Free plan limit?
After 10,000 requests in a calendar month, the proxy returns a
429 Too Many Requests response for any further requests. Your existing data — logs, dashboard stats, and usage history — remains fully accessible.The counter resets automatically on the first of each month. To remove the monthly cap entirely, upgrade to Pro.Can I use Metrion without storing my provider keys?
Can I use Metrion without storing my provider keys?
Yes. Use pass-through mode: pass your provider API key directly as the
api_key (for Anthropic) or Authorization: Bearer token (for OpenAI-compatible providers). Metrion detects that it is not a Metrion token and forwards it to the provider.Your usage is still tracked and visible in your dashboard. Your key is never stored.What providers are supported?

How do I track usage per user or bot?
How do I track usage per user or bot?
Add the
x-metrion-user header to your requests with a string identifier — a user ID, an agent name, or a workflow label. This value appears in the Requester column in your logs and can be filtered from the dashboard.See Request Headers for code examples.How do I export my data?
How do I export my data?
- Logs export (Pro): On the Logs page, click Export CSV to download your request logs.
- Full account export: Go to Settings → Profile → Download my data to download a complete JSON export of your account, including alert rules, usage records, and logs.
Does Metrion modify my requests or responses?
Does Metrion modify my requests or responses?
No. Metrion forwards your request body to the provider as-is and returns the provider’s response unchanged. The only exception is the
anthropic-version header, which Metrion sets to a fixed value server-side for Anthropic requests.Metrion reads usage metadata (token counts, latency) from the response to populate your dashboard, but does not alter the response content.Where is my data stored?
Where is my data stored?
