## Good to know

- Picking several channels publishes a separate cast in each one.
- Casts are measured in bytes, up to 1,024, so accented letters, non-Latin text and emoji fit fewer characters.

## Farcaster questions, answered.

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

### Can I post to Farcaster channels?

Yes. Search for channels in the post settings and PostQueen publishes one cast in each channel you pick. Leave it empty to cast to your home feed.

### How long can a cast be?

Up to 1,024 bytes, so accented letters, non-Latin text and emoji fit fewer characters. PostQueen checks the length before scheduling. Links are sent as plain text.

### Can I attach video to a cast?

No. Casts carry images only, up to 4 per cast.

### Can my AI agent post to Farcaster?

Yes. Once your account is connected, your AI agent can schedule casts, channel posts and reply chains through PostQueen’s MCP server or CLI.
