The Black Forest Labs (BFL) key powers the image-making AI: VisionScaper AI, and the AI Erase, Make it real, and Season and Light tools.

• A Black Forest Labs account with credits added. Use the provider’s dashboard and follow its current instructions.
• WordPress admin access.

1. Open Settings → VisionScaper and find the AI section.
2. Paste your key into Black Forest Labs API key.
3. Leave BFL model as flux-2-klein-4b unless you have a reason to change it. The screen says to leave it as that.
4. Set AI image generations per customer per day.
5. Optionally tick No daily limit for site administrators (for testing).
6. Press Save Changes.

• AI image features turn on for signed-in customers.
• The credits indicator shows in the customer’s account menu.
• The credit store (see Stripe setup) only works when this key, the Stripe key and the store switch are all set.

The settings screen notes an approximate per-image cost for the default model. Prices change. Check the provider’s current pricing before you set the daily limit and any credit packs.

• Test with your own admin account first.
• Keep the daily limit modest at first.
• Customers who run out of free credits can buy more, if you turn the store on.
• Use a separate key for this site so you can revoke it without affecting anything else.

• AI image buttons stay disabled: the BFL key box is empty.
• Images fail after working before: your BFL credit may be used up.
• Pictures use a model you did not expect: check the BFL model box for stray text.
• A customer says “no credits left”: they have used their daily limit. It resets each day.
