The Usage page shows what your lines used this period, any extra charges so far (such as texts sent through the API or Zapier, and carriers' texting registration fees passed on at cost), usage by line, and earlier periods.

## Questions and answers

### Are calls and texts charged per minute or per text?

No. Calling and texting from Onyx Phone and the apps, and voicemail transcripts, are included in your plan. The only extra charges are texts sent through the API or Zapier, and the carriers' texting registration fees, passed on at cost.

### How often does usage update?

About every 15 minutes.

### Where do I see my bill?

On the Billing page, with your plan, card, and invoices. See Billing.

### Why is there a charge for texts sent through Zapier?

Texts that other software sends through the Onyx Phone API or Zapier are billed per segment. Texts your team sends from the website and the apps are included in your plan.
