These are the channels you can publish content to via `POST /v1/publishing/publish`. Each channel includes the platform, account name, username, and whether an Instagram business account is linked (for Facebook pages with Instagram). Only valid (non-expired) connections are returned. Discover connected distribution destinations — Instagram, TikTok, YouTube, and other social accounts linked to your workspace. Call this before `POST /v1/publishing/publish` to get the `accountIds` you'll need. Each channel shows the platform, username, and account type. ## OpenAPI ````yaml GET /v1/publishing/channels openapi: 3.1.0 info: title: Lamina Apps API version: 1.0.0 description: > Professional creative content production for AI agents. Create brand-aligned images, videos, and designs from natural-language briefs using 30+ specialized AI pipelines. Unlike raw model APIs (DALL-E, Flux, Kling), Lamina automatically applies brand guidelines, selects the optimal multi-model pipeline, scores output quality, and delivers permanent CDN-hosted URLs with composability metadata for chaining. ## Authentication All endpoints require an API key passed via one of these headers: - `x-api-key: lma_your_key` (recommended) - `Authorization: Bearer lma_your_key` API keys are workspace-scoped. Create them in **Settings -> API Keys**. ## Quick Start (One-Call Path) `POST /v1/create` with `{ "brief": "product photo of sneakers", "sync": true }` — returns completed output inline with CDN URL. ## Quick Start (Advanced) 1. `GET /v1/apps` -- browse 30+ specialized creative apps 2. `GET /v1/apps/{appId}` -- inspect input parameters 3. `POST /v1/apps/{appId}/runs?webhook=` -- run with your inputs 4. Receive results via webhook, poll `GET /v1/runs/{runId}`, or stream via `GET /v1/runs/{runId}/stream` ## Rate Limits All `/v1/*` endpoints are currently limited to 100 requests per minute per IP. On `429`, read the `RateLimit-*` and `Retry-After` headers before retrying. ## How Inputs Work When running an app, provide inputs as a JSON object keyed by parameter **name** (from the app details response). - **text** parameters: send a string value (e.g. a prompt or description) - **options** parameters: send the **label** of the option (e.g. `"Caucasian"`), not an internal value - **url** parameters: send a publicly accessible URL to an image or video Every parameter is returned with `required: true`. Parameters with a `default` can safely be omitted -- the app will use the default value. ## Endpoint Groups | Group | Purpose | |-------|---------| | **Apps** | Discover and inspect available content creation apps | | **Runs** | Run workflows, track progress, and retrieve results | | **Assets** | Browse generated images, videos, and text from past executions | | **Intelligence** | Brand context, performance prediction, recommendations, and trends | | **Publishing** | Publish content to connected social channels | | **Content** | One-call agent operations: create, score, brief, batch | | **Account** | Credit balance and rate limit visibility | | **Templates** | Content creation templates and strategies | | **Webhooks** | Webhook signature verification | servers: - url: https://app.uselamina.ai description: Production security: - apiKey: [] tags: - name: Create description: Create content from briefs, run specific apps, and use templates - name: Discover description: Find and inspect available apps and their input schemas - name: Track description: Monitor execution progress, retrieve results, and browse generated assets - name: Intelligence description: >- Brand context, performance prediction, content recommendations, and trend signals - name: Distribute description: Publish content to social channels and transfer assets to CDN - name: Score description: Evaluate content quality, brand alignment, and engagement potential - name: Account description: Credit balance, rate limits, and health checks - name: Webhooks description: Webhook signature verification for secure callback handling paths: /v1/publishing/channels: get: tags: - Distribute summary: List Channels description: > List social accounts connected to the workspace.
