Providers and API keys¶
A11yScanFix supports four AI providers. You pay the provider directly with your own key; A11yScanFix never charges per image and never sees your key in plain text - it is stored encrypted in your database.
Supported providers¶
All four read images. Gemini is the default. Pick any one - you only pay that provider for usage.
| Provider | Models in the plugin | Where to get an API key |
|---|---|---|
| Google (Gemini) - default | Gemini 2.5 Flash Lite (default), Gemini 2.5 Flash, Gemini 2.0 Flash | aistudio.google.com/app/apikey |
| OpenAI | GPT-4o mini (default), GPT-4o | platform.openai.com/api-keys |
| Anthropic (Claude) | Claude 3.5 Haiku (default), Claude Sonnet 4 | console.anthropic.com |
| Mistral | Pixtral 12B (default), Pixtral Large | console.mistral.ai/api-keys |
The lighter default models (Gemini Flash Lite, GPT-4o mini, Claude Haiku, Pixtral 12B) are the cheapest and fast enough for alt text. Switch to the larger model only if you want richer descriptions. Google offers a free tier through AI Studio; the others are pay-as-you-go per image.
Getting a key¶
- Create an account with your chosen provider.
- Generate an API key in their dashboard.
- Paste it into A11yScanFix -> AI Alt Text.
- The plugin verifies the key and shows a "Key works" status.
Security¶
Keys are stored encrypted in the WordPress options table and are never sent to A11yScanFix. See Settings and security.
