Install Jentic One Beta
Connect the Email API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Email 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.

Use Cases
Patterns agents use Email API for, with concrete tasks.
★ Communications Operations
Use the Email API to perform communications operations programmatically. The API provides 25 endpoints covering core functionality including send a transactional email, get the list of transactional emails on the basis of allowed filters, get the personalized content of a sent transactional email.
Call POST /smtp/email to send a transactional email
Automated Inbound Management
Automate inbound operations by combining multiple Email API endpoints. Agents can get the list of transactional emails on the basis of allowed filters and then get the personalized content of a sent transactional email in a single workflow.
Call GET /smtp/emails to get the list of transactional emails on the basis of allowed filters, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Email API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle apiKey tokens manually.
Search Jentic for 'send a transactional email', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Email API apiKey credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw secrets never enter the agent context.
Intent-based discovery
Agents search by intent (e.g., 'send a transactional email') and Jentic returns the matching Email API operation with its input schema, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Email API integration: 1-3 days for auth handling, response parsing, and error cases. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using Email API through Jentic.
What authentication does the Email API use?
The Email API uses an API key passed in the `api-key` header. Through Jentic, these credentials are stored encrypted in the MAXsystem vault and injected at execution time, so raw secrets never enter the agent context.
Can I send a transactional email with the Email API?
Yes. Use the POST /smtp/email endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Email API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I send a transactional email through Jentic?
Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'send a transactional email'. Jentic returns the matching Email API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.
How many endpoints does the Email API have?
The Email API exposes 25 endpoints covering inbound, smtp operations.
