You can modify the label, usage context, and all generated content fields. ## OpenAPI ````yaml /openapi.json patch /brand-voices/{id} openapi: 3.0.3 info: title: Mavera API version: 1.0.0 description: >- # Getting Started The Mavera Responses API provides persona-powered AI responses using the **OpenAI Responses API format**. Use `client.responses.create()` with the OpenAI SDK — just set the base URL to `https://app.mavera.io/api/v1`. ## Authentication All API requests require a Bearer token. Create an API key in **Settings > Developer > API Keys**. ``` Authorization: Bearer mvra_live_your_key_here ``` ## Quick Start ### Step 1: Get a Persona ID Every response request requires a `persona_id`. First, list available personas: ```bash curl https://app.mavera.io/api/v1/personas \ -H "Authorization: Bearer mvra_live_your_key_here" ``` This returns personas you can use. Copy the `id` field from any persona. ### Step 2: Create a Response Use the persona ID in your request: ```bash curl https://app.mavera.io/api/v1/responses \ -H "Authorization: Bearer mvra_live_your_key_here" \ -H "Content-Type: application/json" \ -d '{ "model": "mavera-1", "persona_id": "YOUR_PERSONA_ID", "input": "Hello!" }' ``` ## Rate Limits Per-key sliding window limits based on your subscription tier: | Tier | Requests / min | |------|---------------| | Starter | 60 | | Basic | 120 | | Professional | 240 | | Enterprise | 600 | When rate limited, the response includes a `Retry-After` header indicating how many seconds to wait. ## Credits Each API call consumes credits from your subscription. The `usage.credits_used` field in the response shows the cost of each request. contact: name: Mavera Support url: https://mavera.io x-logo: url: /Mavera_Logo_Full.png altText: Mavera servers: - url: https://app.mavera.io/api/v1 description: Production - url: https://dev.mavera.io/api/v1 description: Development security: - BearerAuth: [] tags: - name: System description: Health checks and operational status. - name: Responses description: >- Generate persona-powered AI responses using the OpenAI Responses API format.
