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.
