Connect the Synthesia API to your agent

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

Install Jentic One Beta (Self-Hosted)

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

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 Synthesia API API for, with concrete tasks.

★ Media and Content Operations

Use the Synthesia API to perform media operations programmatically. The API provides 8 endpoints covering core functionality including create a video, list all videos, get a video by id.

Call POST /videos to create a video

Automated Avatars Management

Automate avatars operations by combining multiple Synthesia API endpoints. Agents can list all videos and then get a video by id in a single workflow.

Call GET /videos to list all videos, then verify the result

AI Agent Integration via Jentic

AI agents discover and call Synthesia 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 video', load the operation schema, and execute with Jentic-managed credentials

Why though Jentic?

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

Credential isolation

Synthesia 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., 'create a video') and Jentic returns the matching Synthesia API operation with its input schema, so the agent can call the right endpoint without browsing docs.

Time to first call

Direct Synthesia 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 Synthesia API API through Jentic.

What authentication does the Synthesia API use?

The Synthesia API uses an API key passed in the `Authorization` 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 create a video with the Synthesia API?

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

What are the rate limits for the Synthesia 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 video through Jentic?

Install the Jentic SDK with pip install jentic, authenticate at https://app.jentic.com/sign-up, then search for 'create a video'. Jentic returns the matching Synthesia API operation with its input schema. Load the schema and execute the call — credentials are injected automatically.

How many endpoints does the Synthesia API have?

The Synthesia API exposes 8 endpoints covering avatars, templates, videos operations.
