Question 1

How does API billing work?

Accepted Answer

The SlideSpeak API uses a simple per-slide credit model — 1 credit per slide generated. A 10-slide presentation costs 10 credits. Credits are deducted in real time and your remaining balance is always visible in your dashboard.

Question 2

Do you offer refunds on consumed credits?

Accepted Answer

We don't offer refunds for credits that have been successfully consumed, since each request triggers compute on our end. That said, if you experience a technical issue on our side — a failed generation, an error response, or unexpected behavior — reach out to support and we'll make it right.

Question 3

Is there a free trial or a way to test the API?

Accepted Answer

A paid plan is currently required to access the SlideSpeak API. We recommend starting with the Starter plan ($49/mo) to evaluate the endpoints and output quality. If you're evaluating at scale or need a larger volume to test properly, talk to our sales team — we can work something out.

Question 4

How are credits billed for API integrations like MCP and Zapier?

Accepted Answer

Credit consumption works the same regardless of how you connect — whether you're calling the API directly, using our MCP server with an AI agent, or triggering workflows through Zapier or Make.com. One slide generated always equals one credit consumed.

Question 5

Can I track credit usage per API key?

Accepted Answer

Per-API-key usage filtering isn't available yet, but it's on our roadmap. For now, you can monitor your total credit consumption and billing history from your account dashboard.

Question 6

Do credits roll over month to month?

Accepted Answer

Credits don't roll over — your balance resets at the start of each billing cycle. We'd recommend keeping an eye on your usage in the dashboard toward the end of the month if you want to make the most of your plan. If you're consistently hitting your limit early, it's a good signal to upgrade.

Question 7

Am I charged credits for failed requests?

Accepted Answer

No. If a request fails due to a server-side error or a bug on our end, no credits are deducted. Credits are only consumed when a presentation is successfully generated. If you believe credits were incorrectly charged for a failed generation, contact our support team with the request ID and we'll investigate and restore them.
