For Agents
Provision, scale, fail over, back up, and restore AlloyDB for PostgreSQL clusters and instances on Google Cloud.
Use for: Provision a new AlloyDB cluster in europe-west1, Add a read-pool instance to an existing AlloyDB cluster, Trigger an on-demand backup of an AlloyDB cluster, Restore an AlloyDB cluster from a backup
Not supported: Does not run application SQL queries, manage Postgres roles, or handle non-AlloyDB database services — use for AlloyDB cluster and instance lifecycle only.
The AlloyDB API is the control plane for AlloyDB for PostgreSQL on Google Cloud — Google's PostgreSQL-compatible managed database service tuned for transactional and analytical workloads. It provisions and manages clusters and primary or read-pool instances, runs failover and switchover, drives backups and exports, and supports cluster restore. Application data access still goes through the standard PostgreSQL wire protocol; this API is for lifecycle and operations.
Install Jentic One Beta
Connect the AlloyDB API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AlloyDB API, 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 AlloyDB API.
Create an AlloyDB cluster with primary instance and configure machine type and region
Add or remove read-pool instances to scale read capacity for an existing cluster
Run a controlled failover or switchover on a cluster to test disaster recovery
Trigger an on-demand backup of a cluster and restore from a backup or point-in-time
Export cluster data to Cloud Storage in PostgreSQL dump or CSV format
List long-running operations in a project and cancel an in-flight one
Inject faults into a cluster to validate application failure handling
Use Cases
Patterns agents use AlloyDB API for, with concrete tasks.
★ Provision Production Postgres Infrastructure
Platform teams use the AlloyDB API to spin up production PostgreSQL clusters as part of an environment provisioning pipeline rather than hand-clicking in the Cloud Console. The flow creates a cluster, adds a primary instance, then attaches one or more read-pool instances. The cluster appears as a standard Postgres endpoint that application services connect to with their existing drivers.
POST /v1/projects/{project}/locations/{loc}/clusters with cluster body, then POST /v1/{+parent}/instances with instanceType=PRIMARY, then create READ_POOL instances under the same parent.
Disaster Recovery Drills
Reliability teams need to prove that an AlloyDB-backed service tolerates failover. The API exposes :failover and :switchover on instances and :injectFault on clusters, so a DR drill can be expressed as a runbook that triggers the failover, watches the long-running operation, and verifies that application traffic recovered. This replaces ad-hoc console clicks during scheduled DR exercises.
POST /v1/{+name}:failover on the primary instance, poll the returned operation under /v1/{+name}/operations until done, and verify the cluster's primary IP rotated.
Backup, Restore, and Export Pipeline
A backup automation tool can use the AlloyDB API to schedule on-demand backups of every cluster, list backup objects per project, restore from any backup or point-in-time into a new cluster, and export data to Cloud Storage for archival. This lets compliance-driven teams meet RPO/RTO targets without manual operator steps.
Create a backup with POST /v1/{+parent}/backups, then test restore by POSTing /v1/{+parent}/clusters:restore with backupSource pointing at the backup name.
Agent-Driven Database Operations
An agent integrating AlloyDB through Jentic can express database lifecycle steps as natural-language intents — provision a cluster, add a read pool, take a backup. Jentic isolates the Google Cloud service account and exposes the operation schemas, so an agent stitches a multi-step DR or environment-bootstrap workflow without writing OAuth or LRO polling boilerplate.
Use the Jentic search query 'create an AlloyDB cluster' to discover the operation, then create the cluster, primary instance, and one read-pool instance and report back the connection details.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
AlloyDB uses OAuth 2.0 access tokens minted from a Google Cloud service account. Jentic stores the service account JSON in the encrypted MAXsystem vault and issues short-lived tokens, so the agent never sees the key.
Intent-based discovery
Agents search Jentic with intents like 'create an AlloyDB cluster' or 'fail over an AlloyDB instance' and Jentic returns the matching operation across the 28-endpoint surface with its input schema.
Time to first call
Direct AlloyDB integration takes 2-3 days to handle OAuth, project scoping, and long-running operation polling. Through Jentic, a provision or backup workflow runs in under an hour.

FAQs
Specific to using AlloyDB API through Jentic.
What authentication does the AlloyDB API use?
OAuth 2.0 with the cloud-platform scope, typically via a Google Cloud service account that has the AlloyDB Admin or Editor role. Jentic stores the service account credential in the MAXsystem vault and issues short-lived access tokens to the agent, keeping keys out of agent context.
Can I run application SQL queries through this API?
No. The AlloyDB API is the control plane only — provisioning, lifecycle, backup, and operations. Application data access uses the standard PostgreSQL wire protocol against the cluster's IP and port with a Postgres driver.
What are the rate limits for the AlloyDB API?
AlloyDB control-plane operations are governed by the per-project Google Cloud quota for the AlloyDB service. Long-running operations such as create cluster and restore are throttled to a small number of concurrent operations per project; check IAM and Admin, Quotas in the Cloud Console.
How do I provision an AlloyDB cluster through Jentic?
Search Jentic for 'create an AlloyDB cluster', load the schema for /v1/projects/{project}/locations/{location}/clusters, and execute it. Run pip install jentic and use the async search, load, execute pattern. Then create a primary instance via /v1/{+parent}/instances.
How do I run a failover for testing?
Call POST /v1/{+name}:failover on the primary instance. The API returns a long-running operation; poll /v1/{+name}/operations until done is true. Use :switchover for planned, lower-impact failover.
Is AlloyDB free?
AlloyDB is paid: charges are per vCPU-hour for primary and read-pool instances, per GB of storage, and per GB of backup. See AlloyDB pricing in the Google Cloud Console for the current per-region rates.
