What is listed in the model catalog?

The catalog lists every supported AI model API with its provider, modality (video, image, audio, LLM, or utility), model IDs, parameter constraints, per-call pricing, and an installable model skill. Each model page shows code samples for curl, Python, Node.js, Ruby, and Go, plus skill install commands for Claude Code, Codex, and Gemini CLI.

Can I call different providers with one key?

Yes. A single RunAPI API key works across all supported video, image, music, audio, and LLM models from every provider in the catalog. You do not need separate accounts, separate credentials, or separate billing relationships with any provider. Add a new model from a different provider to your app by changing one model ID parameter — the API key, request shape, and billing all stay the same.

Do I need a separate account per provider?

No. One RunAPI key unlocks the entire catalog. You do not need accounts with Anthropic, OpenAI, Google, Kuaishou, Suno, Black Forest Labs, or any other provider. RunAPI handles provider authentication, rate limiting, and billing consolidation into a single monthly invoice.

How is pricing billed?

Per-call or per-unit metered, billed monthly in USD. There is no subscription, no minimum spend, and no hidden fees. Failed generations are never charged and credits do not expire. The pricing page shows exact per-model costs, and the check_pricing API endpoint returns real-time rates programmatically so you can build cost-aware workflows that check prices before calling a model.

What modalities does the catalog cover?

The catalog spans five modalities. Video generation includes text-to-video, image-to-video, video editing, and video extension from providers like Kling, Veo, Seedance, Hailuo, Wan, Runway, and Luma. Image generation covers text-to-image, image editing, remix, and in-context editing from Flux, Imagen, GPT Image, Seedream, Ideogram, Nano Banana, and more. Music and audio includes full song generation from Suno, text-to-speech and dialogue from ElevenLabs, and sound effects. LLM covers chat, code generation, reasoning, and embeddings from Claude, GPT, Gemini, DeepSeek, GLM, Kimi, MiniMax, and Qwen. Utility includes image and video upscaling from Topaz and Recraft, background removal, and avatar generation.

What are model skills?

Model skills are installable packages that load a model's docs, typed schemas, pricing notes, and setup steps directly into your coding workspace. They work with Claude Code, Codex, Gemini CLI, Cursor, and VS Code. Install a skill with a single command like npx skills add runapi-ai/kling -g and your coding agent immediately has the right context — parameter constraints, endpoint paths, billing units, and code samples — before you write integration code.

Can I self-host the SDK?

Yes. The SDK packages on npm, Packagist, pip, and RubyGems are MIT-licensed. You can self-host, vendor, or fork them. The SDKs are thin clients that handle authentication, async task polling, and typed responses. They connect to the RunAPI endpoint at https://runapi.ai and work with any standard HTTP client.

How do I add a model to my application?

Browse the catalog, pick a model, and install its skill with a single command. The skill loads docs, typed schemas, pricing notes, and setup steps into your coding workspace so your agent has the right context. Then use the provided code samples to integrate the model — set your RunAPI API key, call the endpoint with the model ID and parameters, and handle the response. The entire flow from catalog browsing to a working API call takes under 10 minutes. SDKs are available for Python, Node.js, PHP, Java, Ruby, and Go.

How quickly are new models added to the catalog?

New models are added within days of a provider release. When a provider ships a new model or variant, RunAPI adds API support, per-call pricing, documentation, a model skill, and code samples so you can call the model as soon as it is production-ready. The catalog is updated continuously — you do not need to wait for a scheduled release cycle.

What happens when a provider changes their API?

RunAPI absorbs provider API changes so your integration code does not break. When a provider updates their request format, response structure, or authentication method, RunAPI adapts the proxy layer to maintain the same stable API surface you integrated against, and the SDKs handle format translation automatically.

Where do I report API issues?

Open an issue on the public GitHub repo or email support at contact@runapi.ai. Include the task ID and model ID so the team can investigate. The status page monitors API uptime in real time.

Catalog questions

How do I browse available models?

Visit /models or use the CLI: runapi models list. Filter by modality, provider, or search by name.

Can I use multiple models in one project?

Yes. One API key works across all 240+ models. Switch between video, image, music, audio, and LLM models freely.

How are new models added?

We add new models continuously. Major releases are typically available within days of launch. Follow our changelog for updates.

Can I request a specific model?

Yes. Contact us with the model name and provider. We evaluate all requests and prioritize based on demand.

What happens when a model is retired?

We notify users 30 days before retirement. Your existing code continues working — just update the model parameter to a newer version.

How are models priced?

Text models bill per million input and output tokens; media models bill per second, per image, or per minute. Every rate is listed on the model page and in the pricing table.
