Billing units vary by model, per image, per megapixel or per token. **Leonardo.Ai API.** Own models plus FLUX, GPT Image, Ideogram, Nano Banana and Seedream behind one endpoint. No per-image price list outside the logged-in calculator. ## Before you call either ### fal image models 1. Fetch `https://fal.ai/models//llms.txt` before calling a model to get its schema and price 2. POST to `https://queue.fal.run/` and poll or pass a webhook, rather than holding a call open on fal.run 3. Use an API-scoped key for agents. ADMIN keys can deploy and manage apps 4. Download outputs you need to keep. CDN retention defaults to at least 7 days, set `X-Fal-Object-Lifecycle-Preference` to change it 5. Validate inputs before submitting, a malformed request can still be billed ### Leonardo.Ai API 1. Use `POST /api/rest/v2/generations` with a `model` name such as `lucid-origin` 2. Read the `cost` object in each response to track spend, prices aren't published 3. Send `quality`, not `mode`. `mode` was retired on 2026-05-04 4. Set a webhook callback URL on the key instead of polling long jobs 5. Check the deprecations page before relying on a third-party model, removals follow the provider ## Other comparisons with fal image models or Leonardo.Ai API - [Adobe Firefly API vs fal image models](https://www.anchorterminal.com/compare/adobe-firefly-vs-fal-image.md) - [Adobe Firefly API vs Leonardo.Ai API](https://www.anchorterminal.com/compare/adobe-firefly-vs-leonardo-ai.md) - [Black Forest Labs FLUX API vs fal image models](https://www.anchorterminal.com/compare/black-forest-labs-vs-fal-image.md) - [Black Forest Labs FLUX API vs Leonardo.Ai API](https://www.anchorterminal.com/compare/black-forest-labs-vs-leonardo-ai.md) - [fal image models vs Google Imagen](https://www.anchorterminal.com/compare/fal-image-vs-google-imagen.md) - [fal image models vs Ideogram API](https://www.anchorterminal.com/compare/fal-image-vs-ideogram.md) - [fal image models vs OpenAI Image API](https://www.anchorterminal.com/compare/fal-image-vs-openai-image-api.md) - [fal image models vs Recraft API](https://www.anchorterminal.com/compare/fal-image-vs-recraft.md) - [fal image models vs Replicate image models](https://www.anchorterminal.com/compare/fal-image-vs-replicate-image.md) - [fal image models vs Stability AI Image API](https://www.anchorterminal.com/compare/fal-image-vs-stability-ai-image.md) - [Google Imagen vs Leonardo.Ai API](https://www.anchorterminal.com/compare/google-imagen-vs-leonardo-ai.md) - [Ideogram API vs Leonardo.Ai API](https://www.anchorterminal.com/compare/ideogram-vs-leonardo-ai.md) - [Leonardo.Ai API vs OpenAI Image API](https://www.anchorterminal.com/compare/leonardo-ai-vs-openai-image-api.md) - [Leonardo.Ai API vs Recraft API](https://www.anchorterminal.com/compare/leonardo-ai-vs-recraft.md) - [Leonardo.Ai API vs Replicate image models](https://www.anchorterminal.com/compare/leonardo-ai-vs-replicate-image.md) - [Leonardo.Ai API vs Stability AI Image API](https://www.anchorterminal.com/compare/leonardo-ai-vs-stability-ai-image.md)
