Bannerbear
Bannerbear is a simple API and platform for generating images and videos. Developers and marketers use it to automate the creation of visual content for social media, ads, and more. It's useful for dynamically creating visuals at scale.

Bannerbear Overview
Use action names and parameters as needed.
Working with Bannerbear
This skill uses the Membrane CLI to interact with Bannerbear. Membrane handles authentication and credentials refresh automatically β so you can focus on the integration logic rather than auth plumbing.
Install the CLI
Install the Membrane CLI so you can run membrane from the terminal:
npm install -g @membranehq/cli@latest
Authentication
membrane login --tenant --clientName=
This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.
Headless environments: The command will print an authorization URL. Ask the user to open it in a browser. When they see a code after completing login, finish with:
membrane login complete
Add --json to any command for machine-readable JSON output.
Agent Types : claude, openclaw, codex, warp, windsurf, etc. Those will be used to adjust tooling to be used best with your harness
Connecting to Bannerbear
Use membrane connection ensure to find or create a connection by app URL or domain:
membrane connection ensure "https://bannerbear.com" --json
This is the fastest way to get a connection. The URL is normalized to a domain and matched against known apps. If no app is found, one is created and a connector is built automatically.
If the returned connection has state: "READY", skip to Step 2.
#### 1b. Wait for the connection to be ready
If the connection is in BUILDING state, poll until it's ready:
npx @membranehq/cli connection get --wait --json
The --wait flag long-polls (up to --timeout seconds, default 30) until the state changes. Keep polling until state is no longer BUILDING.
The resulting state tells you what to do next:
READY β connection is fully set up. Skip to Step 2.CLIENT_ACTION_REQUIRED β the user or agent needs to do something. The clientAction object describes the required action:clientAction.type β the kind of action needed:
- "connect" β user needs to authenticate (OAuth, API key, etc.). This covers initial authentication and re-authentication for disconnected connections.
- "provide-input" β more information is needed (e.g. which app to connect to).
- clientAction.description β human-readable explanation of what's needed.
- clientAction.uiUrl (optional) β URL to a pre-built UI where the user can complete the action. Show this to the user when present.
- clientAction.agentInstructions (optional) β instructions for the AI agent on how to proceed programmatically. After the user completes the action (e.g. authenticates in the browser), poll again with membrane connection get to check if the state moved to READY.
CONFIGURATION_ERROR or SETUP_FAILED β something went wrong. Check the error field for details.Searching for actions
Search using a natural language description of what you want to do:
membrane action list --connectionId=CONNECTION_ID --intent "QUERY" --limit 10 --json
You should always search for actions in the context of a specific connection.
Each result includes id, name, description, inputSchema (what parameters the action accepts), and outputSchema (what it returns).
Popular actions
| Name | Key | Description | | --- | --- | --- | | List Animated GIFs | list-animated-gifs | List all animated GIFs in the project. | | Get Animated GIF | get-animated-gif | Retrieve a single animated GIF by its unique ID. | | Create Animated GIF | create-animated-gif | Generate an animated GIF slideshow from a template with multiple frames. | | Get Template | get-template | Retrieve a single template by its unique ID. | | List Templates | list-templates | List all templates in the project. | | List Screenshots | list-screenshots | List all screenshots in the project. | | Get Screenshot | get-screenshot | Retrieve a single screenshot by its unique ID. | | Create Screenshot | create-screenshot | Capture a screenshot of a public webpage. | | List Videos | list-videos | List all videos in the project. | | Get Video | get-video | Retrieve a single video by its unique ID. | | Create Video | create-video | Generate a video from a video template with modifications. | | List Images | list-images | List all images in the project. | | Get Image | get-image | Retrieve a single image by its unique ID. | | Create Image | create-image | Generate an image from a template with modifications. | | Get Account | get-account | Check your account status including quota levels and current usage. |
Running actions
membrane action run --connectionId=CONNECTION_ID --json
To pass JSON parameters:
membrane action run --connectionId=CONNECTION_ID --input '{"key": "value"}' --json
The result is in the output field of the response.
Proxy requests
When the available actions don't cover your use case, you can send requests directly to the Bannerbear API through Membrane's proxy. Membrane automatically appends the base URL to the path you provide and injects the correct authentication headers β including transparent credential refresh if they expire.
membrane request CONNECTION_ID /path/to/endpoint
Common options:
| Flag | Description |
|------|-------------|
| -X, --method | HTTP method (GET, POST, PUT, PATCH, DELETE). Defaults to GET |
| -H, --header | Add a request header (repeatable), e.g. -H "Accept: application/json" |
| -d, --data | Request body (string) |
| --json | Shorthand to send a JSON body and set Content-Type: application/json |
| --rawData | Send the body as-is without any processing |
| --query | Query-string parameter (repeatable), e.g. --query "limit=10" |
| --pathParam | Path parameter (repeatable), e.g. --pathParam "id=123" |
Best practices
membrane action list --intent=QUERY (replace QUERY with your intent) to find existing actions before writing custom API calls. Pre-built actions handle pagination, field mapping, and edge cases that raw API calls miss.π Tips & Best Practices
