# Create a simulation suite

POST https://api.synthflow.ai/v2/simulation_suites
Content-Type: application/json

Create a new simulation suite attached to a specific agent. The suite can only be executed on the agent specified by model_id.

Reference: https://docs.synthflow.ai/api-reference/platform-api/simulations/create-simulation-suite

## Authentication

- `Authorization` header (bearer token, required)

## Servers

- `https://api.synthflow.ai/v2` (Global, default)
- `https://api.us.synthflow.ai/v2` (United States)
- `https://api.eu.synthflow.ai/v2` (European Union)

## Request

### Body (application/json)

- `name` (string, required) — Name of the simulation suite
- `model_id` (string, required) — Agent model ID this suite is for. The suite can only run on this specific agent.
- `language` (string, optional, default: en-US) — Language locale for the persona agent and test cases (e.g., 'en-US', 'es-ES', 'fr-FR'). Must be a valid locale code. Note that 'multi' is not allowed for simulation suites.
