Use this to browse all content your workspace has produced, filter by execution or output type, and retrieve CDN URLs for downstream use (publishing, further processing, etc.). Only assets from completed executions with status `completed` are returned. Results are ordered by creation time, newest first. Returns generated assets (images, videos, text) from past executions in your workspace. Use this endpoint when you need to browse outputs across multiple executions, build a media library view, or let users pick previously generated assets as inputs for new runs. Results are paginated and can be filtered by media type. ## OpenAPI ````yaml GET /v1/assets 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/assets: get: tags: - Track summary: List Assets description: > List generated assets (images, videos, audio, text) from completed executions in your workspace.
