Install Jentic One Beta

Connect the AWS Savings Plans to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS Savings Plans, 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 AWS Savings Plans API.

List available Savings Plan offerings filtered by term, payment option, and product family with DescribeSavingsPlansOfferings

Inspect per-instance discount rates that a given offering applies to with DescribeSavingsPlansOfferingRates

For Agents

Browse, purchase, and inspect AWS Savings Plans commitments to lock in discounted rates on EC2, Fargate, and Lambda usage.

Use for: List all 1-year No Upfront Compute Savings Plan offerings, Get the EC2 instance discount rates that apply under a specific offering, Purchase a 3-year All Upfront Compute Savings Plan at $5 per hour, Show all active Savings Plans on this AWS account

Not supported: Does not provision EC2 instances, query usage metrics, or manage Reserved Instances - use for browsing, purchasing, and inspecting AWS Savings Plans commitments only.

Use Cases

Patterns agents use AWS Savings Plans API for, with concrete tasks.

★ FinOps commitment planning

FinOps teams use DescribeSavingsPlansOfferings and DescribeSavingsPlansOfferingRates to compare 1-year vs 3-year and No Upfront vs All Upfront offerings against their forecasted EC2, Fargate, and Lambda spend. The API returns the exact effective hourly rate per instance family and region, which lets the team model break-even and pick the commitment level that matches their lowest sustained spend.

Call DescribeSavingsPlansOfferings filtered by planTypes=ComputeSP and durations=31536000, then for each offering call DescribeSavingsPlansOfferingRates filtered by usageTypes for EC2 m5.large in us-east-1.

Savings Plan purchase and queueing

Cloud-finance teams use CreateSavingsPlan to lock in a commitment at a specific dollar-per-hour rate, optionally with a future start date so the commitment activates aligned with a budget cycle. DeleteQueuedSavingsPlan allows cancellation before the queued plan activates - useful when forecasts shift between commitment and activation.

Call CreateSavingsPlan with savingsPlanOfferingId for the 1-year No Upfront Compute SP, commitment='5.00', and a clientToken for idempotency.

Existing commitment inventory and audit

Cost-allocation teams use DescribeSavingsPlans to inventory all active and expired commitments on the account, then DescribeSavingsPlanRates to see the per-usage-type rate each commitment applies. Combined with tags applied via TagResource, this drives chargeback reporting that maps Savings Plan benefit to the business unit funding the commitment.

Call DescribeSavingsPlans with no filter to enumerate all plans, then for any plan with end date within 90 days flag it for renewal review.

Agent-driven Savings Plan operations through Jentic

AI agents built into FinOps tooling use Jentic to call DescribeSavingsPlansOfferings, CreateSavingsPlan, and DescribeSavingsPlans without holding raw AWS credentials. Jentic stores keys in your Jentic One instance, signs each request with SigV4, and returns the structured response - letting the agent gather offerings, model spend, and present a recommendation to a human approver before purchase.

Search Jentic for 'list AWS Savings Plan offerings', load DescribeSavingsPlansOfferings, and execute it filtered to the durations and product types matching the team's commitment policy.

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 each request is signed with SigV4 at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'list AWS Savings Plan offerings' or 'find plans expiring soon', and Jentic returns the matching operation like DescribeSavingsPlansOfferings or DescribeSavingsPlans with its input schema so the agent calls it without browsing the AWS docs.

FAQs

Specific to using AWS Savings Plans API through Jentic.

Why is there no official OpenAPI spec for AWS Savings Plans?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call AWS Savings Plans 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 Savings Plans API use?

Savings Plans uses AWS Signature Version 4 HMAC signing with an access key ID and secret access key, optionally with a session token. The service is global, so requests are signed against the us-east-1 endpoint. Through Jentic, your AWS credentials live in your Jentic One instance and Jentic signs each request server-side.

Can I buy a Reserved Instance with the AWS Savings Plans API?

No. This API is for Savings Plans only - Compute SP, EC2 Instance SP, and SageMaker SP. Reserved Instances are purchased through the EC2 API (PurchaseReservedInstancesOffering) and have a different commitment model tied to specific instance families.

What are the rate limits for the AWS Savings Plans API?

AWS does not publish a fixed RPS for Savings Plans in the spec; standard AWS API throttling applies and the service returns ThrottlingException on overage. The deeper limit is product-side: there are quotas on the number of Savings Plans an account can hold, available in the AWS service quotas console.

How do I purchase a Savings Plan with the AWS Savings Plans API through Jentic?

Search Jentic for 'purchase an AWS Savings Plan', load the CreateSavingsPlan operation, and call POST /CreateSavingsPlan with savingsPlanOfferingId, commitment in dollars-per-hour, and a unique clientToken for idempotency. Confirm the result with DescribeSavingsPlans. Install with pip install jentic.

Can I cancel a Savings Plan after it activates with the AWS Savings Plans API?

No - once a Savings Plan activates it cannot be cancelled or refunded; you are committed for the chosen 1-year or 3-year term. Only queued plans (those with a future start date that have not yet activated) can be cancelled, via DeleteQueuedSavingsPlan.

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

Yes. Because you run Jentic One yourself, your own rules decide which Savings Plans operations and credentials the agent may use, so you scope it to only the operations it needs. For read-only FinOps modelling you can allow DescribeSavingsPlansOfferings, DescribeSavingsPlansOfferingRates, and DescribeSavingsPlans while leaving out a committing purchase like CreateSavingsPlan unless you explicitly add it. Since the API takes offering ids, commitments, and filters in the POST request body rather than the URL path, this operation-level control is how you decide whether the agent can browse plans or actually buy one.
