Kraken.io is an image optimization and compression platform that helps reduce image file sizes without compromising quality.
Kraken.io is an image optimization and compression platform that helps reduce image file sizes without compromising quality. On Nagent, Kraken.io is exposed as a fully-configurable images & design integration that any agent can call — 3 actions, and API key authentication. No code is required to wire Kraken.io into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Kraken.io to automate the kinds of tasks images & design teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Kraken.io into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Kraken.io, with input parameters and output schema. Drop these into any step of an agent built in Helix.
KRAKEN_IO_CHECK_USER_STATUSTool to retrieve current Kraken.io account status and quota usage. Use when you need to verify plan limits and remaining quota before processing images.
Input parameters
Your Kraken.io API Key.
Your Kraken.io API Secret.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
KRAKEN_IO_OPTIMIZE_IMAGE_URLTool to optimize an image from a public URL. Use when you need to compress, resize, or convert an externally hosted image. Returns result immediately if 'wait' is true.
Input parameters
Development mode (no real optimization)
Publicly accessible URL of the image to optimize
Authentication credentials for Kraken API
Return image also in AVIF format
Return optimization result synchronously if true
Return image also in WebP format
Use lossy optimization mode
Resize options sub-object
Convert options sub-object for image format conversion
Compression quality (0-100) for lossy mode
Use lossless optimization mode
S3 storage options sub-object
Preserve image metadata (EXIF, IPTC) in output
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
KRAKEN_IO_PRESERVE_METADATATool to preserve EXIF and other metadata during Kraken.io image optimization. Use when you need to maintain metadata while compressing images.
Input parameters
Use developer mode (no real optimization)
Remote image URL to optimize, required if `file` is not provided
Authentication credentials for Kraken.io API
Binary content of the image to upload, required if `url` is not provided
Return result synchronously when true
Use lossy optimization mode
Image quality for lossy mode (0-100)
S3 storage parameters for optimized image.
Filename for the uploaded file when using `file`
Preserve all EXIF and other metadata when true
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 83 agents privately built on Nagent that already use Kraken.io.
Build on Nagent
Connect Kraken.io to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Kraken.io, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Kraken.io is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Kraken.io is connected, you configure its 3 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Kraken.io steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Kraken.io event fires, the agent kicks off automatically.
Every Kraken.io action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Kraken.io ships with 3 pre-built images & design actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Kraken.io together with other connected tools.
