For Agents

Render templated images at scale by supplying parameters to Duply templates. Useful for personalised social cards, ad creative, and bulk visual content jobs.

Quickstart

Get started with Duply API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"generate a templated image from parameters"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with Duply API API.

List available design templates via GET /templates

Render a single image from a template via POST /generate

Render an image using URL-encoded parameters via POST /generate/url

Run a bulk render job via POST /batch and track it via GET /batch/{batchId}

List historical renders via GET /renders and download or delete a specific render

Not supported: Does not handle template design, image hosting outside Duply renders, or video editing beyond template substitution — use for templated image generation and batch rendering only.

Jentic publishes the only available OpenAPI specification for Duply API, keeping it validated and agent-ready. Duply is a templated image and video generation service that turns design templates plus dynamic parameters into rendered assets, with batch support and ready-made integrations to Zapier and Make. The API exposes 13 endpoints across templates, generation (single and URL-parameter), batch jobs, render history, and asset uploads. Authentication uses an API key passed in the Authorization header.

Use Cases

Patterns agents use Duply API API for, with concrete tasks.

★ Personalised Open Graph Images per Blog Post

Auto-generate a unique Open Graph image for each blog post or product page by populating a Duply template with the title, author, and accent colour. POST /generate returns a hosted image URL the agent stores against the post, so social shares always show on-brand creative without designer involvement.

POST /generate with template_id, layers={title:'New Post', author:'Sophie'}, store the returned image_url against the blog post record

Bulk Ad Creative from a Spreadsheet

Render hundreds or thousands of personalised ad images from a single template plus a row-per-variant data source. POST /batch dispatches the job, and GET /batch/{batchId} returns progress and the URLs for each completed render. This replaces manual design work for outreach, retargeting, and A/B test variants.

POST /batch with template_id and 1000 layer-value rows, then poll GET /batch/{batchId} until status='completed' and download each render URL

Brand-Asset Library for Generation

Maintain a Duply asset library of logos, fonts, and product photos so generated images stay on-brand without re-uploading every time. POST /assets uploads new files and GET /assets lists the library, which an agent can reference by id when calling /generate or /batch. This keeps templates portable and brand changes centralised.

POST /assets with the new logo file, then update each affected template to reference the returned asset_id

Agent-Driven Visual Content Pipeline via Jentic

Wire Duply into agent workflows that draft, render, and publish visual content. Through Jentic the agent searches by intent, loads the schema for /generate or /batch, and executes — the API key in the Authorization header stays in the Jentic vault, not the agent's prompt context.

Search Jentic for 'generate templated image', load the schema for POST /generate, and execute with the template_id and layer values supplied by the parent content workflow

Why though Jentic?

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

Credential isolation

Duply API keys are stored encrypted in the Jentic vault. Agents receive scoped access at execution, so the raw Authorization value never enters the agent's prompt context.

Intent-based discovery

Agents search Jentic by intent (for example 'generate a templated image' or 'run a batch render') and Jentic returns the matching Duply operation with its input schema.

Time to first call

Direct Duply integration: half a day for auth, layer mapping, and batch polling. Through Jentic: under 30 minutes — search, load schema, execute.

FAQs

Specific to using Duply API API through Jentic.

Why is there no official OpenAPI spec for Duply API?

Duply does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Duply API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Duply API use?

Duply uses an API key passed in the Authorization header. Through Jentic the key is stored in the encrypted vault and injected at execution, so the raw value never enters the agent's prompt context.

Can I generate images at scale with the Duply API?

Yes. POST /batch starts a bulk render job from one template plus many layer-value rows, and GET /batch/{batchId} returns progress and the resulting render URLs.

What are the rate limits for the Duply API?

The OpenAPI spec does not declare rate limits. Plans set per-minute and monthly render quotas in the Duply dashboard; have your agent handle HTTP 429 with exponential backoff.

How do I render a single templated image through Jentic?

Search Jentic for 'generate templated image', load the schema for POST /generate, and execute with template_id plus the layer values you want substituted. Install with pip install jentic.

Can I upload my own logo and fonts to Duply?

Yes. POST /assets uploads a file and returns an asset_id you can reference inside templates so renders stay on-brand. List, retrieve, and delete them under /assets.
