# FAQ

## How do I get access?

Nozomi is available to approved users. [**Request access via this form →**](https://form.typeform.com/to/pGXN0ryV?utm_source=docs\&utm_medium=cta\&utm_campaign=nozomi_access\&utm_content=faq)

## Rate Limits

Each API key has an associated rate limit. Rate limits are applied **per region** — sending the same transaction to multiple regions does not count against your limit.

#### QoS Priority

If your transactions have a high failure rate, Nozomi applies a QoS penalty to your priority. For example, if only 10% of your transactions land successfully over the last 30 minutes, your effective priority is discounted to 10%.

To maintain high QoS priority:

* Check account state before submitting to avoid predictable failures.
* Avoid sending transactions that will fail due to stale blockhashes.
* Monitor your landing rate and reduce volume if it drops.

## Custom Limits

High-volume users can request custom rate limits and priority configurations. Reach out via Discord.

## Does Nozomi Simulate Transactions?

No. Nozomi does not simulate transactions. It routes directly to the TPU for the fastest possible delivery.
