# Fish Audio

Expressive multilingual and production-grade text-to-speech with RunAPI-managed MP3 delivery.

Fish Audio provides focused speech synthesis models for conversational, narrative, and production voice workflows. RunAPI exposes s1 and s2-pro through one synchronous text-to-speech contract.

## Install a model skill

```sh
npx skills add runapi-ai/<line> -g
```

Replace `<line>` with a model slug from this provider, then use the skill docs, schemas, pricing notes, and setup steps while adding the model feature.

## FAQ

### Is this an official Fish Audio integration?

RunAPI exposes a managed API surface with transparent per-call pricing, fully documented capability and parameters, and clear error behavior. You get the same model output quality without managing a direct provider relationship or provider-side account.

### Do I need a Fish Audio account?

No. Your RunAPI API key is enough for managed access to all Fish Audio models. You do not need to create a separate account, manage provider-specific credentials, or handle provider-side billing.

### What&#39;s the latency overhead from proxying through RunAPI?

Typically under 20 ms. RunAPI keeps the proxy layer close to model execution regions to minimize added latency. Media generation time is dominated by the model itself, not the proxy.

### Are images / videos cached?

Generated outputs are stored and retrievable by task ID. You can fetch completed results at any time using the task status endpoint or the RunAPI dashboard. Output URLs remain accessible for the retention period shown in the API docs. Inputs are not cached or stored.

### Can I bring my own key?

Not currently. Calls use RunAPI-managed access, which simplifies authentication and lets RunAPI handle rate limiting, retries, and billing consolidation on your behalf.

### How is billing consolidated?

All API calls across all providers appear on a single monthly USD invoice. There is no per-provider billing, no subscription, and no minimum spend. Failed generations are never charged.

### What SDKs can I use with Fish Audio models?

Official SDKs are available for Python, Node.js, PHP, Java, Ruby, and Go. Each SDK handles authentication, async task polling, and typed responses. For LLM models, the OpenAI and Anthropic SDKs also work by pointing the base URL to RunAPI.

### What are model skills and how do they work?

Model skills are installable packages that load a model&#39;s docs, typed schemas, pricing notes, and setup steps directly into your coding workspace. Install a skill with one command and your agent has the right context before you write integration code. Skills work with Claude Code, Codex, Gemini CLI, Cursor, and VS Code.

### How do I switch between Fish Audio models?

Change the model parameter in your API request. All Fish Audio models share the same API key, the same request shape, and the same billing. No code changes, no re-authentication, and no separate billing setup are required when switching between models or between variants of the same model. You can also switch to models from other providers by changing the same parameter — the API surface is unified across the entire catalog.
