## How to connect a Krea API key to Phersa

1. ### Step 1: Get a Krea API key

    Sign in at krea.ai, open API tokens in your settings and create a token. That token is your Krea API key. Krea bills generations to your Krea account, so make sure it has enough balance.

    [krea.ai/settings/api-tokens →](https://www.krea.ai/settings/api-tokens)
2. ### Step 2: Add the key in Phersa

    In Phersa, open Settings, go to API keys and choose Krea. Paste the key and click Save & verify.

3. ### Step 3: Let Phersa check it

    Before saving, Phersa tests the key with Krea, and a key Krea rejects is not stored. Saved keys are encrypted. Krea has no balance API, so check your balance in Krea.

4. ### Step 4: Generate

    In the app, pick a model that runs on Krea. You see the cost in dollars before you generate, such as $0.08 for a 1K Nano Banana 2 image.

### MCP server details

- Provider keys are added in Phersa Settings only. The Phersa MCP server cannot read, add or change them.
- settings-keys-status shows which providers, including Krea, are connected.
- jobs-create defaults to dry\_run=true and returns a plan without spending. dry\_run=false starts a real generation that spends the user's Krea balance.

## What is different about Krea in Phersa

- Krea prices API generations in US dollars. It has no balance API, so Phersa cannot show your Krea balance; check it in Krea.
- Grok Imagine Video 1.5 on Krea takes one start image with no image fee, and costs $0.14 and $0.25 per second at 720p and 1080p.
- Grok Imagine Image 2.0 on Krea starts at $0.042 (1K · Low), vs $0.04 on SpaceXAI, and adds $0.0105 per reference image, up to 3.
- GPT Image 2.5 Sunburst on Krea is one model for text and for edits, with a size and a quality and up to 10 reference images. Krea publishes no price for it, so this page and the Generate button show no dollar.
- Gemini Omni 1.1 Flash on Krea makes 3 to 10 second clips with up to 10 reference images. Krea does not take a resolution setting, so the price shown follows fal's and WaveSpeedAI's per-second rates.
- Nano Banana 2 on Krea costs $0.08, $0.12 and $0.16 at 1K, 2K and 4K, the same whether you start from text or reference images (up to 14).

## Krea questions

### What is Krea?

Krea (krea.ai) is a generative AI creative suite for making and editing images and videos, with a developer API. Its app plans use compute units, while API calls draw from a separate prepaid US dollar balance. Krea was started by Victor Perez and Diego Rodriguez.

[Visit krea.ai ↗](https://www.krea.ai)

### How much does Nano Banana 2 cost on Krea?

On Krea, Nano Banana 2 costs $0.08 for a 1K image, $0.12 for 2K and $0.16 for 4K.

### Does Phersa charge extra on top of Krea?

No. Generations bill to your own Krea account at Krea's price, and Phersa adds no markup. The Phersa plan is a separate $99 per month.

[See Phersa pricing →](https://phersa.com/#pricing)

### Does Krea have a free tier or free credits?

Not for the API. Krea's Free plan gives 100 compute units a day in the web app, but API calls use a separate prepaid US dollar balance with a $5 minimum top-up. Terms can change.

[Check Krea API billing ↗](https://www.krea.ai/features/api)

### Which models can I use with a Krea key in Phersa?

Images: Nano Banana 2, GPT Image 2.5 Sunburst and Grok Imagine Image 2.0. Video: Gemini Omni 1.1 Flash and Grok Imagine Video 1.5. Voice Swap runs on ElevenLabs Voice Changer, so it needs an ElevenLabs key.

[Voice Swap with ElevenLabs →](https://phersa.com/elevenlabs)

### How do I connect my Krea API key to Phersa?

Create an API token at krea.ai/settings/api-tokens. In Phersa, open Settings, go to API keys, choose Krea and paste it. Phersa checks the key with Krea before saving it.

### Is Krea cheaper than SpaceXAI for Grok Imagine Video 1.5?

At 720p and 1080p, they cost the same. Prices are for an 8-second clip. Krea does not charge for the start image, where SpaceXAI adds $0.01 per reference image.

[See SpaceXAI prices →](https://phersa.com/spacexai)

### Does Phersa show a price for GPT Image 2.5 Sunburst on Krea?

No. Krea's API docs publish no dollar amount for GPT Image 2.5 Sunburst, so the Generate button and this page leave it blank. Krea still bills your account. For Gemini Omni 1.1 Flash, Krea does not take a resolution setting, so Phersa shows fal's and WaveSpeedAI's per-second rates.

### Why doesn't Phersa show my Krea balance?

Krea has no balance API, so Phersa cannot read it. Your key still works for every model; check your balance in Krea.

### What happens when my Krea balance runs out?

Krea refuses the job, and Phersa shows the error, usually “Out of credits”. Top up your Krea account, then generate again.

### Is my Krea API key safe in Phersa?

Phersa tests the key with Krea before saving it, stores it encrypted and uses it only for generation. AI agents connected over MCP cannot read or change it. Removing the key in Settings deletes it permanently.
