True API Unification

One API. Every Model. We Handle the Differences.

Every model has quirks: different parameter names, varying output formats. Providers add complexity with async vs. sync APIs and more. Lumenfall normalizes everything so you write once and it works everywhere.

Automatic Transformation

Request 1024x1024 – We translate

Different models use different size parameters. Some want pixels, others want aspect ratios or megapixel tiers. You always use your preferred format. We convert it for each model.

You send

size: "1024x1024"
Lumenfall transforms per model

Model receives

// fal.ai FLUX Pro:
aspect_ratio: "1:1", megapixels: "1"
// OpenAI GPT Image 1:
size: "1024x1024"

Stay with the SDK you're already using. You don't change, we change for you.

Why Lumenfall

Everything you need to ship AI features, nothing you don't

Stop wrestling with multiple provider APIs, billing accounts, and reliability concerns. Get back to building.

One API, every model

All important generative AI models - Nanobanana, Imagen, Flux, Stable Diffusion and more - through a single, OpenAI-compatible interface. No SDK juggling.

One bill, zero markup

Pay what you use at official provider rates. One wallet, one invoice. Full cost visibility per request.

Built-in resilience

330+ edge locations with automatic failover. When one provider hiccups, traffic reroutes instantly. 5ms overhead.

Production Ready

Built for Scale, Reliability & Speed

01

Automatic Failover, Zero Downtime

When providers fail, your app doesn't.

Your requests automatically reroute to the next available provider—no code changes, no manual intervention, no failed generations. Sub-second detection means users never know a failover happened.

Sub-Second Detection

The moment a request fails, we're already retrying with the next provider.

Invisible to Users

Your end users never know a failover happened. They just get their image.

Transparent, Usage-Based Pricing

Pay only for what you use at official provider rates. No platform fees, no markup - just the actual cost of generation.

Zero Markup

Get all the advantages of Lumenfall—unified API, automatic polling, format conversion—while only paying for the tokens you use. No service fees, no hidden costs.

Pure Usage-Based

No subscriptions, no tiers, no minimum commitments. Generate one image or one million—you're billed exactly for what you use, down to the token.
