Content

Overview

Recoup’s content API gives you seven independent primitives for generating and editing visual content. Each primitive does one thing well. You orchestrate them. Every primitive works without a template. Pass your own prompt, reference images, and parameters directly. Templates are optional shortcuts — opinionated creative recipes that pre-fill parameters for a specific look.

Primitives

Primitive	Endpoint	What it does
Generate Image	POST /api/content/image	Create an image from a text prompt, optionally with a reference image for face/style
Generate Video	POST /api/content/video	Create a video — 6 modes: prompt, animate, reference, extend, first-last, lipsync
Generate Caption	POST /api/content/caption	Generate on-screen text for social media videos
Transcribe Audio	POST /api/content/transcribe	Transcribe audio to timestamped lyrics/text
Edit Content	PATCH /api/content	Trim, crop, resize, overlay text, or add audio — one processing pass
Upscale	POST /api/content/upscale	Upscale image or video resolution (up to 4x)
Analyze Video	POST /api/content/analyze	AI video analysis — describe scenes, check quality, evaluate content

There is also POST /api/content/create which runs the full pipeline in one call — use it when you want a video without creative control over each step.

How It Works

Without a template (malleable mode)

Pass your own parameters directly to any primitive. Maximum creative control.

# Generate an image with your own prompt
curl -X POST https://api.recoupable.dev/api/content/image \
  -H "x-api-key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "A moody portrait in a dimly lit room, front-facing phone camera"}'

# Generate a video from that image
curl -X POST https://api.recoupable.dev/api/content/video \
  -H "x-api-key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"image_url": "IMAGE_URL_FROM_ABOVE", "prompt": "subtle breathing motion, nearly still"}'

With a template (shortcut mode)

Pass a template ID and the primitive fills in prompts, reference images, and style rules automatically. You can still override any parameter.

# Same image, but the template provides the prompt and reference images
curl -X POST https://api.recoupable.dev/api/content/image \
  -H "x-api-key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"template": "artist-caption-bedroom", "reference_image_url": "YOUR_FACE_IMAGE"}'

Use GET /api/content/templates to see available templates with descriptions.

Templates

A template is a complete creative recipe — it defines what a piece of content looks like across every primitive:

Image config: prompt, reference images, style rules (camera, lighting, composition)
Video config: mood variations, movement descriptions
Caption config: tone, formatting rules, example captions
Edit config: crop ratio, text overlay style, audio mixing

Templates are optional. They save time by pre-filling parameters with curated defaults. When you see customers repeatedly creating the same kind of content, that pattern becomes a template.

Override priority

When using a template, your explicit parameters always win:

Your params — highest priority. What you pass overrides everything.
Artist context — if the artist has a style guide, it personalizes the template.
Template defaults — lowest priority. The recipe’s built-in values.

Video Modes

The video primitive supports 6 generation modes:

Mode	What it does	Required inputs
`prompt`	Create from text description	`prompt`
`animate`	Animate a still image	`image_url`, `prompt`
`reference`	Use image as style reference (not first frame)	`image_url`, `prompt`
`extend`	Continue an existing video	`video_url`, `prompt`
`first-last`	Transition between two images	`image_url`, `end_image_url`, `prompt`
`lipsync`	Sync face to audio	`image_url`, `audio_url`

Set mode explicitly, or omit it and the API infers the mode from the inputs you provide.

Iteration

Each primitive is independent. Redo any step without rerunning the whole pipeline:

Bad image? Regenerate with a different prompt or reference
Caption too long? Regenerate with length: "short"
Video glitchy? Analyze it, then regenerate with adjusted params
Clip too short? Use extend mode to continue it
Low quality? Upscale the image or video
Everything good but wrong caption? Just re-run the edit step

Content Agent (Slack Bot)

The Recoup Content Agent is a Slack bot that generates social-ready artist videos on @mention. It plugs into the content creation pipeline and delivers results directly in your Slack thread.

@Mention Syntax

@RecoupContentAgent <artist_account_id> [template] [batch=N] [lipsync]

Parameter	Required	Description
`artist_account_id`	Yes	UUID of the artist account
`template`	No	Content template name. Optional — when omitted, the pipeline runs with default settings. See GET /api/content/templates for options.
`batch=N`	No	Number of videos to generate (1-30, default 1)
`lipsync`	No	Enable lipsync mode (audio baked into video)

Examples

Basic — single video with default template:

@RecoupContentAgent abc-123-uuid

Custom template:

@RecoupContentAgent abc-123-uuid artist-caption-bedroom

Batch with lipsync:

@RecoupContentAgent abc-123-uuid batch=3 lipsync

Architecture

Component	Location	Purpose
Slack webhook	`POST /api/content-agent/slack`	Receives @mention events
Callback endpoint	`POST /api/content-agent/callback`	Receives polling results
Bot singleton	`lib/content-agent/bot.ts`	Chat SDK with Slack adapter + Redis state
Mention handler	`lib/content-agent/handlers/`	Parses args, validates artist, triggers pipeline
Poll task	`poll-content-run` (Trigger.dev)	Monitors content runs, posts results via callback

Data Flow

Slack event → POST /api/content-agent/slack handles the webhook
Mention handler parses the command, calls GET /api/content/validate to check artist readiness
Content creation triggered via POST /api/content/create — returns runIds
Poll task (poll-content-run) monitors the Trigger.dev runs every 30 seconds (up to 30 minutes)
Callback → POST /api/content-agent/callback receives results and posts video URLs back to the Slack thread

Setup

1. Create a Slack App

Go to api.slack.com/apps and create a new app
Under OAuth & Permissions, add bot scopes:
- chat:write — post messages
- app_mentions:read — receive @mention events
Under Event Subscriptions:
- Enable events
- Set the request URL to https://api.recoupable.dev/api/content-agent/slack
- Subscribe to app_mention bot event
Install the app to your workspace

2. Configure Environment Variables

Variable	Where	Description
`SLACK_CONTENT_BOT_TOKEN`	API (Vercel)	Bot OAuth token (`xoxb-...`) from Slack app
`SLACK_CONTENT_SIGNING_SECRET`	API (Vercel)	Signing secret from Slack app Basic Information
`CONTENT_AGENT_CALLBACK_SECRET`	API + Tasks	Shared secret for callback authentication (generate a random string)
`RECOUP_API_KEY`	API + Tasks	Recoup API key for authenticating pipeline requests
`RECOUP_API_BASE_URL`	Tasks (Trigger.dev)	API base URL (e.g., `https://api.recoupable.dev`)

3. Verify

Mention the bot in any Slack channel where it’s been added:

@RecoupContentAgent <your-artist-account-id>

You should see:

An immediate acknowledgment message
A video URL reply in the thread after ~5-10 minutes

Troubleshooting

Issue	Cause	Fix
No response from bot	Event subscription URL not configured	Check Slack app Event Subscriptions
”Artist not found”	Invalid `artist_account_id`	Verify the UUID exists in the platform
”No GitHub repository found”	Artist missing repo config	Ensure the artist account has a linked GitHub repo
Timeout after 30 min	Pipeline took too long	Check Trigger.dev dashboard for the failed run
”Unsupported template”	Invalid template name	Use `GET /api/content/templates` to list available templates
