For Agents
Store and query schemaless attribute data in Amazon SimpleDB domains. Agents can create domains, put and batch-put attributes, fetch attributes by item, and run Select queries.
Use for: I need to create a SimpleDB domain to store user profile attributes, Write a batch of items into a SimpleDB domain in one call, Retrieve all attributes for a specific item from SimpleDB, Run a Select query against SimpleDB to filter items by attribute value
Not supported: Does not handle relational joins, transactions, full-text search, or large-object storage - use for small-to-medium schemaless attribute data only.
Jentic publishes the only available OpenAPI specification for Amazon SimpleDB, keeping it validated and agent-ready. Amazon SimpleDB is a schemaless, automatically indexed key-value data store that exposes domain, item, and attribute primitives over a query API. Agents can create domains, put and get attributes on items, run select-style queries, and perform batched mutations without managing servers, indexes, or replication. SimpleDB targets small-to-medium structured datasets where simplicity and elasticity matter more than transactional joins.
Install Jentic One Beta
Connect the Amazon SimpleDB to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amazon SimpleDB, 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%2Famazon-simpledb" | 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%2Famazon-simpledb" | 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 SimpleDB API.
Create and delete SimpleDB domains that hold structured item-attribute data
Write attributes to items using PutAttributes and BatchPutAttributes for bulk loads
Read attributes for a specific item with GetAttributes including consistent-read mode
Run Select queries with SQL-style predicates over a domain to return matching items
Inspect domain size, item count, and attribute statistics via DomainMetadata
Delete attributes or whole items selectively with DeleteAttributes and BatchDeleteAttributes
Use Cases
Patterns agents use Amazon SimpleDB API for, with concrete tasks.
★ Lightweight Metadata Store for Application Objects
Use SimpleDB as a schemaless catalog for object metadata that does not justify a relational database. Applications create one domain per logical entity, write attributes via PutAttributes, and query with Select to retrieve matching items. SimpleDB indexes every attribute automatically, so adding new fields needs no migration and queries do not require pre-defined indexes.
Create a domain named 'product-catalog', PutAttributes for item 'sku-1001' with name, price, and category, then run Select to fetch all items where category = 'audio'.
Configuration and Feature Flag Storage
Store feature flags, environment-scoped configuration, and small lookup tables in SimpleDB so multiple services can read and update them without operating a database. BatchPutAttributes loads many flags at once and consistent reads ensure freshly written values are returned on the next GetAttributes call. Suitable for small-to-mid scale systems where feature flag volume is bounded.
BatchPutAttributes into the 'feature-flags' domain to set 10 flag values for the staging environment, then GetAttributes with ConsistentRead=true to verify the writes.
Bulk Cleanup and Domain Lifecycle Management
Operations teams use SimpleDB to maintain domains over time: rotating expired records with BatchDeleteAttributes, decommissioning domains with DeleteDomain, and auditing capacity via DomainMetadata. Because SimpleDB pricing scales with stored attributes, periodic cleanup keeps cost predictable.
Call DomainMetadata on 'audit-logs', then BatchDeleteAttributes for any item whose timestamp attribute is older than 90 days.
AI Agent Schemaless Workspace via Jentic
AI agents using Jentic can treat SimpleDB as scratch storage for task state, intermediate results, and per-session memory. Through Jentic, the agent searches for the SimpleDB write or query operation by intent, loads the input schema, and executes against the vault-stored AWS credentials. No SDK or signing logic is needed in the agent runtime.
Search Jentic for 'put attributes on a SimpleDB item', load the PutAttributes schema, and write three attributes for item 'session-42' in the 'agent-memory' domain.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring Amazon SimpleDB by hand means implementing AWS SigV4 signing and the older Query API serializer that encodes each action and its attributes into form parameters against the sdb.amazonaws.com endpoint. Through Jentic you install once, import Amazon SimpleDB from the API Directory, store your AWS access key and secret once, and your agent calls it.
Permission scoping
SimpleDB passes the domain name and item attributes as Query API parameters in the request rather than in a URL path, so scope your agent to the operations it needs: for example allow PutAttributes, GetAttributes, and Select for a read-write workspace. You choose the operations it may call, so DeleteDomain and BatchDeleteAttributes are not included unless you add them.
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 'put attributes on a SimpleDB item' or 'run a Select query over a domain', and Jentic returns the matching operation like PutAttributes or Select with its input schema so the agent calls it without browsing the AWS reference.

FAQs
Specific to using Amazon SimpleDB API through Jentic.
Why is there no official OpenAPI spec for Amazon SimpleDB?
AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amazon SimpleDB 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 Amazon SimpleDB use?
Amazon SimpleDB uses AWS Signature Version 4 (HMAC-based request signing) with an access key ID and secret access key. Through Jentic, these credentials are stored encrypted in the vault and never enter the agent's context - the agent receives a scoped session and Jentic signs each request before it reaches the SimpleDB endpoint.
Can I run SQL-style queries against the Amazon SimpleDB?
Yes. The Select action accepts a SQL-like expression over a single domain (for example, 'select * from product-catalog where category = "audio"') and returns matching items with their attributes. Joins across domains are not supported - design one domain per logical entity.
What are the rate limits for the Amazon SimpleDB?
SimpleDB throttles based on per-domain throughput rather than fixed per-second limits. Each domain is capped at 10 GB of data and roughly 25 writes per second per item; BatchPutAttributes accepts up to 25 items per call. Beyond that, requests are throttled with a ServiceUnavailable response and should be retried with exponential backoff.
How do I write a batch of items into SimpleDB through Jentic?
Through Jentic, search for 'batch put attributes simpledb', load the BatchPutAttributes input schema, then execute a single call with up to 25 items in the Items array. Jentic handles the SigV4 signing and returns the response with no additional AWS SDK setup.
Is the Amazon SimpleDB free?
SimpleDB has a free tier covering the first 25 machine hours, 1 GB of storage, and 1 GB of data transfer per month. Beyond that, AWS charges for machine hours consumed by queries, stored data, and data transfer. Pricing is documented at https://aws.amazon.com/simpledb/pricing/.
Can I limit what my agent is allowed to do with the Amazon SimpleDB API?
Yes. Because you run Jentic One yourself, you decide which SimpleDB operations your agent may call, and your own rules govern that scope. For a read-write workspace you can allow PutAttributes, GetAttributes, and Select while leaving destructive actions like DeleteDomain and BatchDeleteAttributes out, so the agent cannot invoke them. Your AWS access key and secret stay encrypted on your instance and are signed into each request at execution time rather than exposed to the agent.
