Install Jentic One Beta

Connect the Amazon Elastic Compute Cloud to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amazon Elastic Compute Cloud, 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.

Capabilities

What an agent can do with Amazon Elastic Compute Cloud API.

Launch and terminate EC2 instances with RunInstances and TerminateInstances at the requested instance type and AMI

Manage EBS volumes via CreateVolume, AttachVolume, DetachVolume, and DeleteVolume tied to instances

Define VPC networking with CreateVpc, CreateSubnet, CreateRouteTable, and CreateInternetGateway

For Agents

Provision and manage EC2 instances, EBS volumes, AMIs, VPC networking, security groups, and the broad surface of AWS compute and network resources.

Use for: Launch a t3.medium EC2 instance from a specific AMI, Stop all running EC2 instances tagged Environment=dev, Create a VPC with two public and two private subnets, Authorize port 443 ingress on a security group

Not supported: Does not handle Auto Scaling Groups, Elastic Load Balancing, or container orchestration - use for EC2 instances, EBS volumes, and VPC networking primitives only.

Jentic publishes the only available OpenAPI specification for Amazon Elastic Compute Cloud, keeping it validated and agent-ready. Amazon EC2 provides resizable compute capacity in AWS, and its API is the foundational control plane for EC2 instances, EBS volumes, VPC networking, security groups, and a broad set of related compute primitives. With more than a thousand operations, the API spans instance lifecycle, AMIs, key pairs, networking (VPC, subnets, route tables, NAT, VPN), elastic IP addresses, transit gateways, and capacity reservations. Use it when an agent needs to provision compute, manage networking, or automate any AWS infrastructure-as-API workflow.

Use Cases

Patterns agents use Amazon Elastic Compute Cloud API for, with concrete tasks.

★ Provision a Fleet of Compute Instances

Use RunInstances to launch one or more EC2 instances of a chosen type from an AMI, attach them to a security group, and place them in a target subnet. The same call sets tags, IAM instance profiles, and user data, giving an agent everything needed to bring up workers, application servers, or batch hosts in one structured call.

Call RunInstances with ImageId, InstanceType t3.medium, MinCount 1, MaxCount 1, the chosen SubnetId, and a SecurityGroupIds list, then poll DescribeInstances until State.Name is running.

Stand Up a Production VPC

Compose a production-ready network by chaining CreateVpc, CreateSubnet for each AZ, CreateInternetGateway, CreateRouteTable, CreateNatGateway, and the route association calls. The result is a fully tagged VPC with predictable CIDR layout that workloads can be deployed into without console clicks.

Call CreateVpc with the requested CidrBlock, CreateSubnet for each AZ, CreateInternetGateway, AttachInternetGateway, then CreateRouteTable and CreateRoute to wire up egress.

Lock Down Inbound Access with Security Groups

Tighten access to a workload by replacing broad CIDR allow rules with narrow ones. AuthorizeSecurityGroupIngress adds the permitted port and source CIDR, RevokeSecurityGroupIngress removes outdated rules, and DescribeSecurityGroups gives an audit-friendly view of effective rules per group.

Call AuthorizeSecurityGroupIngress with the GroupId, IpProtocol tcp, FromPort 443, ToPort 443, and the approved CIDR ranges, then DescribeSecurityGroups to verify.

Agent-Driven Infrastructure as API

An AI agent connected via Jentic can interpret a runbook, locate the right EC2 operations, and provision compute and networking changes - launch instances, rotate AMIs, scale Auto Scaling-friendly groups, or rebuild VPC routes - without leaving the conversation. Jentic returns the matching EC2 operation and schema across the 1000+ operation surface so the agent can pick the right call.

Search Jentic for 'launch an EC2 instance', load RunInstances, execute it with the requested InstanceType, ImageId, SubnetId, and SecurityGroupIds, then DescribeInstances until running.

Why Jentic?

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

Credential isolation

Your AWS access keys for EC2 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 'launch an EC2 instance' or 'create a security group rule', and Jentic returns the matching EC2 operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Amazon Elastic Compute Cloud API through Jentic.

Why is there no official OpenAPI spec for Amazon Elastic Compute Cloud?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amazon Elastic Compute Cloud 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 Amazon EC2 API use?

EC2 uses AWS Signature Version 4 (HMAC) signing with an AWS access key ID and secret access key. Through Jentic, those credentials live encrypted in your Jentic One instance and are injected into signed requests at execution time, so the agent never sees the raw secret access key.

Can I launch and tag instances in one call?

Yes. RunInstances accepts a TagSpecifications parameter that applies tags to the instance and any volumes created by the launch. There is no need to call CreateTags separately for instances launched this way.

What are the rate limits for the Amazon EC2 API?

EC2 enforces per-account, per-region request limits that vary by operation; describe operations have higher limits than write operations such as RunInstances. Specific numbers are not in the spec; the AWS user guide documents them, and ThrottlingException responses should trigger exponential backoff.

How do I launch an instance through Jentic?

Search Jentic for 'launch an EC2 instance', load RunInstances, then execute it with ImageId, InstanceType, MinCount, MaxCount, SubnetId, and SecurityGroupIds. Run pip install jentic and use the async search and execute pattern.

Does this API include Auto Scaling and Elastic Load Balancing?

No. EC2 covers instances, volumes, AMIs, and VPC networking. Auto Scaling Groups and Elastic Load Balancers live in their own AWS APIs (autoscaling and elasticloadbalancingv2) and require separate operations to manage.

Can I limit what my agent is allowed to do with the AWS EC2 API?

Yes. Because Jentic One is self-hosted, your own rules decide which EC2 operations and AWS credentials the agent may use. EC2 dispatches every action through a single endpoint with the operation named in the request, so you can scope the agent to only the calls it needs, such as DescribeInstances or AuthorizeSecurityGroupIngress. Destructive operations like TerminateInstances stay out of that set unless you explicitly add them.
