## Good to know

- Paste your private key in hex. A key in nsec form is read the wrong way and signs as the wrong identity.
- Your key is stored on PostQueen’s server so it can sign notes at the scheduled time.
- A note counts as sent when any of the five relays accepts it.

## Nostr questions, answered.

Anything else? Write to [support@postqueen.ai](mailto:support@postqueen.ai) and a person answers.

### Which key format does PostQueen need?

Your Nostr private key in hex form. Don’t paste the nsec form: it is read as hex and signs as the wrong identity. Convert it to hex first.

### Is my Nostr key stored?

Yes. PostQueen stores the key on its server so it can sign each note at the time you scheduled. Connect a key you are comfortable using this way.

### Which relays receive my notes?

Five well-known relays: nos.lol, relay.damus.io, relay.snort.social, temp.iris.to and vault.iris.to. A note counts as published when any of them accepts it. You can’t pick your own relays.

### Can my AI agent post to Nostr?

Yes. Add PostQueen to your AI agent through the MCP server or the CLI and ask it for notes or threads; PostQueen signs and broadcasts them at the scheduled time.
