Upload videos first using the Upload Media endpoint to get media_ids. Video input requires additional credits for video analysis (cost scales with video length).

Source URLs

Provide website URLs to give the AI additional context for research. PowerPost scrapes each URL and uses the content to generate more informed captions.

Request Body

Field	Type	Required	Description
`prompt`	string	Yes	What you want to post about (max 2,000 characters)
`post_types`	string[]	Yes	Target post types (at least one)
`research_mode`	string	Yes	`regular` or `deep`
`source_urls`	string[]	No	URLs to scrape for context (max 10)

Example

curl -X POST https://powerpost.ai/api/v1/content/generate \
  -H "x-api-key: pp_live_sk_YOUR_KEY" \
  -H "X-Workspace-Id: YOUR_WORKSPACE_ID" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Announce our new product launch",
    "post_types": ["instagram-reel", "linkedin-post"],
    "research_mode": "regular",
    "source_urls": ["https://example.com/product-page"]
  }'

Each URL adds to the generation cost. URLs must use HTTPS. Private/internal URLs are filtered out for security.

Common Parameters

Headers

Header	Value
`x-api-key`	Your API key
`X-Workspace-Id`	Your workspace ID
`Content-Type`	`application/json`

Post Types

Specify which post types to generate for. The platform is derived automatically from each post type.

Platform	Post Types
Instagram	`instagram-feed`, `instagram-reel`, `instagram-story`
TikTok	`tiktok-video`, `tiktok-photos`
YouTube	`youtube-video`, `youtube-short`
X	`x-post`
Facebook	`facebook-post`, `facebook-reel`, `facebook-story`
LinkedIn	`linkedin-post`

Multiple post types from the same platform (e.g., instagram-reel and instagram-feed) produce one shared caption for that platform. The post type declares your publishing intent.

Research Modes

Mode	Description
`regular`	Quick generation with basic research
`deep`	Extended research for higher engagement

Writing Styles

Create custom writing styles in Settings → Writing Styles. A writing style captures your brand voice so generated content sounds like you.

Pass the writing_style_id to apply a style:

{
  "prompt": "We just shipped dark mode",
  "post_types": ["instagram-reel"],
  "research_mode": "regular",
  "writing_style_id": "c3d4e5f6-a7b8-9012-cdef-345678901234"
}

If omitted, the generation uses your active writing style (if you have one set), or defaults to no style.

Response

  "status_url": "/api/v1/content/generations/550e8400-e29b-41d4-a716-446655440000"
}

Field	Type	Description

`status`	string	Initial status (always `processing`)
`credits_used`	number	Credits deducted for this generation
`remaining_credits`	number	Your credit balance after deduction
`status_url`	string	Relative URL to poll for results

Use the Get Generation endpoint to poll for results.

Credit Costs

Credit costs depend on:

Research mode — Deep research costs more than regular
Platform count — More unique platforms require more credits
Input type — Image and video require extra credits for processing
Video duration — Longer videos cost more

See the Credits endpoint to check your current balance.

Errors

Code	Description
400	Invalid request body
