For Agents
Model industrial assets, ingest sensor telemetry, and query historical and aggregated property values from factory, energy, and utility equipment.
Use for: I need to ingest temperature readings from a fleet of pumps, Retrieve the latest pressure values across every asset in a refinery, Get the aggregated hourly average of a turbine power output, List all assets in a SiteWise asset model hierarchy
Not supported: Does not handle MQTT messaging, edge code deployment, or general device shadow management - use for industrial asset modelling, sensor data ingestion, and historical querying only.
Jentic publishes the only available OpenAPI specification for AWS IoT SiteWise, keeping it validated and agent-ready. AWS IoT SiteWise is a managed service that collects, organises, and analyses data from industrial equipment at scale. It models physical assets such as wind turbines, production lines, and chemical reactors as digital twins, ingests time-series property values from MQTT or OPC-UA gateways, and exposes the data through 73 endpoints covering assets, asset models, properties, gateways, portals, and dashboards. The service runs aggregations on the fly and supports SiteWise Monitor portals so operators can browse live and historical metrics without standing up custom dashboards.
Install Jentic One Beta
Connect the AWS IoT SiteWise to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS IoT SiteWise, 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Famazonaws.com%2Fiotsitewise" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Famazonaws.com%2Fiotsitewise" | 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 AWS IoT SiteWise API.
Model industrial equipment as asset hierarchies via /asset-models and /assets endpoints
Stream property values in batch through /properties/batch/putAssetPropertyValue
Query aggregated, historical, and latest property values across asset fleets
Provision and configure SiteWise Edge gateways for on-premises OPC-UA collection
Create SiteWise Monitor portals, projects, and dashboards for operator visibility
Associate time-series aliases with asset properties for cross-source data unification
Run interpolation queries to fill gaps in irregular sensor sampling intervals
Use Cases
Patterns agents use AWS IoT SiteWise API for, with concrete tasks.
★ Industrial Asset Modelling
Represent physical equipment such as turbines, conveyors, and compressors as structured digital assets with typed properties, hierarchies, and computed metrics. AWS IoT SiteWise stores asset models that describe the schema of equipment classes, then instantiates assets that inherit those models. Engineers can roll up child asset metrics to parent assets, enabling fleet-wide and site-wide views without custom data pipelines.
Create an asset model named WindTurbine with properties for RotorSpeed, PowerOutput, and BladePitch, then instantiate three assets bound to that model
Sensor Data Ingestion at Scale
Collect time-series telemetry from thousands of sensors using SiteWise Edge gateways, MQTT publishers, or direct API writes. The /properties/batch/putAssetPropertyValue endpoint accepts up to 10 entries per call with multiple value timestamps each, suitable for high-frequency industrial workloads. Data flows into time-series storage with built-in retention, and computed properties evaluate transforms and metrics as new values arrive.
Push a batch of 50 timestamped pressure readings from sensor S-204 into the BoilerPressure property of asset asset-9f3b
Operator Dashboards and Portals
Provide manufacturing and energy operators with live visibility into plant performance through SiteWise Monitor portals. Portals organise projects and dashboards backed by SSO, and dashboards reference asset properties directly so they update as new telemetry arrives. The /portals, /projects, and /dashboards endpoints let teams provision the entire visibility layer from infrastructure-as-code rather than the console.
Provision a SiteWise Monitor portal named 'Plant 7 Operations' with a project containing one dashboard wired to the BoilerPressure and SteamFlow properties
Historical Trend and Aggregate Analysis
Investigate equipment behaviour by querying aggregated metrics over arbitrary time windows. The /properties/batch/aggregates and /properties/batch/history endpoints return min, max, average, sum, and standard deviation across one or many assets at minute, hour, or day resolution. Reliability engineers use these queries to spot drift, schedule maintenance, and feed analytics notebooks without exporting raw data.
Fetch the hourly average of property prop-rotor-speed for asset asset-9f3b across the last 24 hours
AI Agent Industrial Operations
AI agents call AWS IoT SiteWise through Jentic to read live and historical equipment data, instantiate assets when new gear is commissioned, and surface anomalies to maintenance staff. Through Jentic, an agent searches for the right SiteWise operation by intent, loads the schema, and submits the call with credentials kept in your Jentic One instance. This avoids the multi-day overhead of building bespoke SigV4 request signing into agent runtimes.
Search Jentic for 'get latest sensor reading from industrial asset', load the BatchGetAssetPropertyValue schema, and execute it for asset asset-9f3b property prop-temp

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the IoT SiteWise API by hand means building AWS Signature Version 4 signing, selecting the right regional host from iotsitewise.{region}.amazonaws.com, wiring IAM roles, and handling AWS throttling and retries yourself. Through Jentic you install once, import AWS IoT SiteWise from the API Directory, store the AWS access key and secret once, and your agent calls it.
Permission scoping
IoT SiteWise carries asset and property ids in the request body of its batch read and write operations, so limit the agent to the operations it needs, such as BatchGetAssetPropertyValue for reads or CreateAssetModel for setup. You choose the operations it may call, so destructive ones like DeleteAsset or DeletePortal are not included unless you add them.
Credential isolation
Your AWS access key and secret for IoT SiteWise are stored once, encrypted, by your own Jentic One instance and 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 'read the latest reading from an industrial sensor' or 'create an iot asset model', and Jentic returns the matching IoT SiteWise operation with its input schema so the agent calls the right endpoint without reading the AWS reference.

FAQs
Specific to using AWS IoT SiteWise API through Jentic.
Why is there no official OpenAPI spec for AWS IoT SiteWise?
AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call AWS IoT SiteWise 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 IoT SiteWise API use?
AWS IoT SiteWise uses AWS Signature Version 4 (SigV4) HMAC request signing. Each request must be signed with an access key, secret key, and optional session token scoped to the IoT SiteWise IAM permissions. Through Jentic, these credentials are stored encrypted in the vault and applied at execution time, so the agent never sees raw secrets.
Can I ingest time-series sensor data with the AWS IoT SiteWise API?
Yes. Use POST /properties/batch/putAssetPropertyValue to submit up to 10 entries per call, where each entry can carry multiple timestamped values. For higher throughput, deploy a SiteWise Edge gateway and configure OPC-UA or MQTT data sources, which write into the same property records via the gateway endpoints.
How do I model a piece of industrial equipment with AWS IoT SiteWise through Jentic?
Search Jentic for 'create iot sitewise asset model', load the schema for POST /asset-models, and submit the model definition with measurement, transform, and metric properties. Then call POST /assets to instantiate the asset bound to that model. Jentic handles SigV4 signing for both calls.
What are the rate limits for the AWS IoT SiteWise API?
Rate limits vary by operation and AWS Region. Asset property data writes default to 10 entries per request and ingestion quotas scale per region; read operations such as BatchGetAssetPropertyValue have separate transactions-per-second limits documented in the AWS service quotas console. Check your account's IoT SiteWise quotas before high-volume runs.
Can the AWS IoT SiteWise API run aggregations across many assets at once?
Yes. POST /properties/batch/aggregates accepts entries that span multiple asset IDs and property IDs and returns aggregate values such as average, sum, minimum, maximum, count, and standard deviation across the window you specify.
Does AWS IoT SiteWise support on-premises data collection?
Yes. SiteWise Edge gateways run on AWS IoT Greengrass and connect to OPC-UA servers and other industrial protocols at the plant. Use the /20200301/gateways endpoints to register gateways, then attach data source configurations to push values into the cloud.
Can I limit what my agent is allowed to do with the AWS IoT SiteWise API?
Yes. Because you run your own self-hosted Jentic One instance, your rules decide which of the 73 IoT SiteWise operations the agent may call, so you can allow reads such as BatchGetAssetPropertyValue while withholding writes and setup calls like CreateAssetModel. Destructive operations such as DeleteAsset and DeletePortal are excluded unless you explicitly add them. Since asset and property ids travel in the request bodies of the batch read and write operations, you constrain access at the operation level and pair it with AWS credentials scoped to the matching IoT SiteWise IAM permissions.
