For Agents
Investigate, archive, and act on Amazon GuardDuty findings and manage detectors, member accounts, threat intel sets, and malware scan plans across an AWS organisation.
Use for: I need to enable GuardDuty in a new region with all data sources turned on, List high-severity findings across the organisation in the last 7 days, Archive a finding once an analyst has confirmed it is a false positive, Add an IP CIDR to a trusted IP set so internal scanners stop triggering alerts
Not supported: Does not handle log ingestion, vulnerability scanning, or incident response automation — use for GuardDuty threat detection management and finding triage only.
Jentic publishes the only available OpenAPI specification for Amazon GuardDuty, keeping it validated and agent-ready. Amazon GuardDuty is a continuous threat detection service that analyses VPC flow logs, CloudTrail events, DNS logs, EKS audit logs, and EBS volume data to surface suspicious activity in AWS accounts. The API covers full lifecycle management of detectors, findings, threat intelligence sets, IP allow lists, member accounts, malware protection plans, and publishing destinations across 67 operations.
Install Jentic One Beta
Connect the Amazon GuardDuty to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amazon GuardDuty, 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 | sh2
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 instanceJentic 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 GuardDuty API.
Create and configure GuardDuty detectors with selected data sources and feature toggles
List and retrieve security findings with filtering by severity, type, and resource
Archive and unarchive findings to triage incidents at scale
Manage trusted IP sets and threat intel sets that suppress or escalate detections
Invite, accept, and manage GuardDuty member accounts under a single administrator
Configure malware protection scan plans for EC2 instances and EBS volumes
Publish findings to S3, EventBridge, or Security Hub via destinations and filters
Use Cases
Patterns agents use Amazon GuardDuty API for, with concrete tasks.
★ Centralised Multi-Account Threat Detection
Configure a delegated GuardDuty administrator account that aggregates findings from every member account in an AWS organisation. The API exposes EnableOrganizationAdminAccount, CreateMembers, InviteMembers, and ListMembers so an agent can onboard or audit accounts at scale. Findings flow into the administrator account where they can be filtered, archived, or republished.
Call EnableOrganizationAdminAccount for the security account, then CreateMembers with a list of AccountDetail entries and InviteMembers to send the invitation
Automated Finding Triage
Pull GuardDuty findings on a schedule, classify them by severity and type, archive low-severity false positives, and route the remainder to a SIEM or ticketing system. ListFindings supports rich filter criteria, GetFindings returns full detail for a batch, and ArchiveFindings closes off resolved cases. UpdateFindingsFeedback feeds analyst decisions back to AWS.
Call ListFindings with FindingCriteria filtering severity >= 7 and updatedAt within the last 24 hours, then GetFindings for the returned IDs
Custom Threat Intelligence Feeds
Add organisation-specific threat intelligence by uploading IOC lists to S3 and registering them as ThreatIntelSets. GuardDuty correlates incoming events against the lists and raises a CustomThreatIntel finding when a match occurs. The API also manages IPSets — trusted ranges that suppress noisy detections from known scanners or load balancers.
Call CreateThreatIntelSet with a Location pointing to an S3 object containing IOCs in TXT format, Activate=true, and a Format of TXT
AI Agent Security Operations
Through Jentic, an AI agent can act as an SOC analyst — paginating through findings, archiving false positives by pattern, updating IP allow lists, and triggering malware scans on suspicious EC2 instances. The 67 GuardDuty operations are exposed as Jentic tools so the agent picks the right one from intent.
Search Jentic for 'archive guardduty finding', load the ArchiveFindings schema, and execute it with the DetectorId and a list of FindingIds

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
AWS access keys for GuardDuty are stored encrypted in the Jentic vault. Agents never see the raw credentials — Jentic signs each request with SigV4 server-side.
Intent-based discovery
Agents search Jentic with intents like 'list guardduty findings' or 'archive a finding' and get the matching operation back with its input schema.
Time to first call
Direct integration: 1-2 days to wire up the AWS SDK and IAM policies for security operations. Through Jentic: under an hour.

FAQs
Specific to using Amazon GuardDuty API through Jentic.
Why is there no official OpenAPI spec for Amazon GuardDuty?
AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amazon GuardDuty via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Amazon GuardDuty API use?
The API uses AWS Signature Version 4 (HMAC) request signing. Through Jentic, AWS credentials are stored encrypted in the vault and requests are signed server-side, so the agent never holds raw access keys.
Can I list and filter GuardDuty findings with the API?
Yes. Call ListFindings on /detector/{detectorId}/findings with a FindingCriteria object that filters by severity, type, resource, or updatedAt. Pass the returned IDs to GetFindings to retrieve full finding details.
What are the rate limits for the Amazon GuardDuty API?
AWS applies per-account, per-region request quotas to GuardDuty operations and these vary by call. List operations have higher throughput than mutation operations like CreateDetector or InviteMembers. Check AWS Service Quotas for current limits.
How do I archive a finding through Jentic?
Search Jentic for 'archive guardduty finding', load the ArchiveFindings schema, and execute with the DetectorId and a list of up to 50 FindingIds. The archived findings remain queryable but no longer count as active.
Can I add custom threat intelligence to GuardDuty?
Yes. Upload an IOC list to S3 in TXT, STIX, OTX_CSV, ALIEN_VAULT, PROOF_POINT, or FIRE_EYE format and call CreateThreatIntelSet with the Location, Format, and Activate=true. GuardDuty raises a Custom finding type when an event matches an entry.
