Install Jentic One Beta

Connect the AWS Compute Optimizer to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS Compute Optimizer, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

For Agents

Fetch right-sizing and idle-resource recommendations across EC2, Auto Scaling, EBS, Lambda, ECS-Fargate, and RDS, and export them to S3.

Use for: I need to find oversized EC2 instances I can downsize, I want to export Lambda right-sizing recommendations to S3, Get the recommendations for a specific Auto Scaling group, List all idle EBS volumes in this account

Not supported: Does not handle automatic right-sizing actions, billing analysis, or general performance monitoring - use only to fetch right-sizing recommendations and export them.

Use Cases

Patterns agents use AWS Compute Optimizer API for, with concrete tasks.

★ EC2 Right-Sizing for Cost Reduction

FinOps and platform teams need to identify EC2 instances that are over-provisioned. AWS Compute Optimizer's GetEC2InstanceRecommendations returns recommended instance types ranked by estimated monthly savings and performance risk, based on at least 14 days of CloudWatch metrics. Acting on the top recommendations typically yields 20-40% compute cost reduction.

Call GetEC2InstanceRecommendations for the current account and return the top 10 instances by estimated monthly savings.

Lambda Memory Tuning

Lambda billing scales with allocated memory and duration. AWS Compute Optimizer's GetLambdaFunctionRecommendations recommends a memory size that minimizes cost while keeping latency within risk bounds. Applying the recommendation is a single UpdateFunctionConfiguration call per function.

Call GetLambdaFunctionRecommendations and return the recommended memory size and projected savings for a given function ARN.

Idle Resource Cleanup

Engineering organizations accumulate idle EC2 instances, EBS volumes, and Auto Scaling groups that incur cost without delivering value. AWS Compute Optimizer's GetIdleRecommendations surfaces these resources with confidence-rated idle classifications so they can be stopped, deleted, or scheduled.

Call GetIdleRecommendations and return all resources classified as Idle along with their estimated monthly savings.

Agent-Driven FinOps Reports

An AI agent supporting a FinOps team can pull recommendations across EC2, Auto Scaling, EBS, Lambda, ECS, and RDS in one pass and generate a prioritized savings plan. Through Jentic, each operation is one structured call - no boto3 setup or pagination boilerplate.

Call GetRecommendationSummaries, then GetEC2InstanceRecommendations and GetLambdaFunctionRecommendations, and return the top 20 savings opportunities ranked by estimated monthly impact.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your AWS access key and secret are stored once, encrypted, by your own Jentic One instance and injected at execution time when the request is signed. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'find oversized EC2 instances and Lambda functions' or 'list idle resource recommendations', and Jentic returns the matching Compute Optimizer operation with its input schema, so the agent calls the correct endpoint without browsing the AWS service reference.

FAQs

Specific to using AWS Compute Optimizer API through Jentic.

Why is there no official OpenAPI spec for AWS Compute Optimizer?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call AWS Compute Optimizer via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the AWS Compute Optimizer API use?

AWS Signature v4 (HMAC) with IAM permissions on compute-optimizer:Get* and compute-optimizer:Export* actions. Jentic isolates the AWS credentials and signs each request from its vault.

Can I get Lambda memory recommendations with the AWS Compute Optimizer API?

Yes. GetLambdaFunctionRecommendations returns one or more memory-size options per function, with estimated cost savings and a performance risk rating. Recommendations require at least 14 days of CloudWatch invocation metrics.

What are the rate limits for the AWS Compute Optimizer API?

Per-account, per-region TPS limits apply to all Get* operations. Use ExportEC2InstanceRecommendations and similar export operations to fetch large recommendation sets without paginating thousands of Get calls.

How do I export right-sizing recommendations through Jentic?

Search Jentic for 'export EC2 right-sizing recommendations to S3', load the ExportEC2InstanceRecommendations schema, and execute it with the destination S3 bucket and object key. Compute Optimizer writes the CSV file and returns the job ID.

Is the AWS Compute Optimizer API free?

The basic recommendations are free. Enhanced infrastructure metrics for EC2 require an opt-in and incur a small per-resource monthly charge. Export operations are free aside from S3 storage of the output.

Can I limit what my agent is allowed to do with the AWS Compute Optimizer API?

Yes. Because you run Jentic One yourself, your own rules decide which Compute Optimizer operations and credentials the agent may use, and scoping here is by operation since the API selects each action through the X-Amz-Target header rather than a URL path. You can restrict the agent to read-only calls like GetEC2InstanceRecommendations, GetLambdaFunctionRecommendations, or GetRecommendationSummaries, so write and export actions such as ExportEC2InstanceRecommendations are not available unless you explicitly add them. The AWS access key and secret stay stored on your instance and are injected only when a permitted request is signed.
