For Agents

Programmatically create a transmission, list scheduled transmissions. Covers 27 operations with apiKey authentication.

Install Jentic One Beta

Connect the SparkPost API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the SparkPost 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 | sh

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 instance

Jentic 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 SparkPost API for, with concrete tasks.

★ Communications Operations

Use the SparkPost API to perform communications operations programmatically. The API provides 27 endpoints covering core functionality including create a transmission, list scheduled transmissions, get transmission details.

Call POST /transmissions to create a transmission

Automated Transmissions Management

Automate transmissions operations by combining multiple SparkPost API endpoints. Agents can list scheduled transmissions and then get transmission details in a single workflow.

Call GET /transmissions to list scheduled transmissions, then verify the result

AI Agent Integration via Jentic

AI agents discover and call SparkPost 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 'create a transmission', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your SparkPost API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'send an email' or 'get deliverability metrics over time', and Jentic returns the matching SparkPost operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

Time to first call

FAQs

Specific to using SparkPost API through Jentic.

What authentication does the SparkPost API use?

The SparkPost API uses an API key passed in the `X-API-Key` header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.

Can I create a transmission with the SparkPost API?

Yes. Use the POST /transmissions endpoint. The API returns structured JSON responses that agents can parse and act on directly.

What are the rate limits for the SparkPost 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 create a transmission through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create a transmission'. Jentic returns the matching SparkPost API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

How many endpoints does the SparkPost API have?

The SparkPost API exposes 27 endpoints covering transmissions, metrics, templates operations.

Can I limit what my agent is allowed to do with the SparkPost API?

Yes. Because you run Jentic One yourself, your own rules decide which SparkPost operations and credentials the agent may use, so you can grant only what it needs, such as creating a transmission or reading deliverability metrics. A destructive operation like deleting a scheduled transmission stays out of reach unless you explicitly add it. Note that transmission recipients travel in the request body rather than a resource path, so scoping is done at the operation level rather than per recipient.
