Install Jentic One Beta

Connect the AWS Cost and Usage Report Service to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS Cost and Usage Report Service, 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 Cost and Usage Report Service API.

Modify an existing report definition to change format, granularity, or schema columns

List all CUR report definitions in the account

For Agents

Manage AWS Cost and Usage Report definitions that deliver hourly billing line items to S3 in CSV or Parquet.

Use for: I need to create a Cost and Usage Report that lands in my S3 bucket, I want to switch my CUR from CSV to Parquet, List all Cost and Usage Report definitions in this account, Delete an unused CUR report definition

Not supported: Does not handle interactive cost analysis, budget alerts, or forecasting - use only to manage Cost and Usage Report definitions that deliver line items to S3.

Use Cases

Patterns agents use AWS Cost and Usage Report Service API for, with concrete tasks.

★ FinOps Data Lake Foundation

FinOps teams pipe AWS billing detail into a data lake so they can attribute spend to teams, products, and tags. AWS CUR's PutReportDefinition creates an hourly-granularity Parquet report that lands in S3 ready for Athena, Redshift, or QuickSight to query. Setup takes under an hour, after which the report is delivered automatically.

Call PutReportDefinition with Format=Parquet, Compression=Parquet, TimeUnit=HOURLY, an S3Bucket and S3Prefix, and AdditionalSchemaElements=[RESOURCES].

Chargeback and Showback by Tag

Engineering organizations need to charge back AWS spend to internal cost centers using tags. Enabling AdditionalSchemaElements=RESOURCES in a CUR report and filtering by cost-allocation tags downstream is the standard pattern. ModifyReportDefinition can update an existing definition rather than recreating it.

Call ModifyReportDefinition for an existing report to enable RESOURCES in AdditionalSchemaElements and SPLIT_COST_ALLOCATION_DATA in AdditionalArtifacts.

Lifecycle Management of Old Reports

When teams reorganize, old CUR definitions accumulate and continue writing to stale S3 buckets. DescribeReportDefinitions lists all current report definitions, and DeleteReportDefinition removes ones that are no longer needed.

Call DescribeReportDefinitions, identify reports whose S3Bucket starts with 'legacy-', then call DeleteReportDefinition for each.

Agent-Configured Billing Reports

An AI agent helping a FinOps lead can configure CUR reports on demand for new accounts and consolidate definitions across an organization. Through Jentic, each operation is one structured call with no SigV4 boilerplate.

For each new account in the organization, call PutReportDefinition with a standard Parquet hourly definition writing to a per-account prefix in the central billing bucket.

Why Jentic?

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

Credential isolation

Your AWS credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'create a Cost and Usage Report that writes to S3' or 'list existing report definitions', and Jentic returns the matching AWS Cost and Usage Report Service operation with its input schema so the agent calls the right endpoint without browsing the AWS service reference.

FAQs

Specific to using AWS Cost and Usage Report Service API through Jentic.

Why is there no official OpenAPI spec for AWS Cost and Usage Report Service?

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

AWS Signature v4 (HMAC) with IAM permissions on cur:* actions and the underlying S3 bucket. Jentic stores the AWS credentials in its vault and signs the requests on the agent's behalf.

Can I create a Parquet Cost and Usage Report with the API?

Yes. Call PutReportDefinition with Format=Parquet and Compression=Parquet, plus AdditionalArtifacts including ATHENA so the report is queryable via Athena out of the box.

What are the rate limits for the AWS Cost and Usage Report API?

The API itself is configuration-only with low TPS limits - PutReportDefinition, ModifyReportDefinition, and DeleteReportDefinition are infrequent operations and each account is limited to a small number of report definitions in total.

How do I create a CUR report through Jentic?

Search Jentic for 'create a Cost and Usage Report that writes to S3', load the PutReportDefinition schema, and execute it with the report name, S3 bucket, S3 prefix, format, and refresh settings. Reports begin delivering on the next billing run.

Is the AWS Cost and Usage Report API free?

The API and CUR delivery are free. You pay only for S3 storage of the delivered files and for any Athena, Redshift, or QuickSight queries you run against them.

Can I limit what my agent is allowed to do with the AWS Cost and Usage Report API?

Yes. Because Jentic One is self-hosted, you decide which of this API's operations your agent may call, even though every request routes through a single endpoint with the action named inside it. For example, you can allow only DescribeReportDefinitions so the agent can list report definitions, while withholding PutReportDefinition, ModifyReportDefinition, and DeleteReportDefinition. The AWS credentials stay under your control and are injected only for the operations you have permitted.
