Jentic publishes the only available OpenAPI specification for the Bannerbear API, keeping it validated and agent-ready. Bannerbear automates image and video generation from designer-built templates, exposing endpoints for one-off images, batched collections, animated GIFs, screenshots of URLs, and rendered videos. Each render request supplies modifications (text, image swaps, colour overrides) to a template, and Bannerbear returns hosted output assets ready to embed in social posts, landing pages, or email. The API is widely used for personalised marketing creatives and dynamic OG images.

Use Cases

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

★ Personalised Marketing Creatives at Scale

Generate thousands of personalised images for email, social, and ad campaigns by feeding customer data into Bannerbear templates. Marketing teams design templates once in Bannerbear's editor and then drive variations through POST /v2/images, swapping recipient names, product photos, and colour themes. This replaces handcrafted Photoshop work and cuts campaign turnaround from days to minutes.

POST /v2/images with template UID 'tpl_abc' and modifications mapping the customer's name, product image URL, and brand colour, then return the image_url from the response.

Dynamic Open Graph and Social Cards

Generate per-page Open Graph images for blog posts, product pages, and shareable links using Bannerbear templates. Drop a request to POST /v2/images at publish time or render on demand from a serverless function for share-time previews. Pair with /v2/screenshots when an actual rendered page snapshot is preferable to a templated card.

POST /v2/images for blog post 'how-to-rank-on-google' with the post title and author headshot, then store the returned image_url on the post record for OG meta tags.

Short-Form Video and Animated Ad Production

Produce short-form videos and animated GIFs at scale by sending modifications to /v2/videos and /v2/animated_gifs. Bannerbear handles transcoding, frame composition, and audio overlay, so marketing teams iterate on creative variants without owning a video pipeline. Useful for social ads, product highlight reels, and animated email banners.

POST /v2/videos with template UID 'vid_promo' and modifications for product name, price, and a stock background, then poll GET /v2/videos/{uid} until status is completed.

AI Agent Creative Producer via Jentic

Wire an AI agent to Bannerbear through Jentic so it can act as an on-demand creative producer. The agent searches Jentic for an intent like 'generate a marketing image', loads the Bannerbear schema, and executes the call with the API key held in the Jentic vault. The agent can compose copy, choose templates, and return finished image URLs to a chat UI or email draft.

Search Jentic for 'create a marketing image', execute POST /v2/images against template 'tpl_promo' with copy generated by the agent, and post the rendered image_url to Slack.

Why though Jentic?

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

Credential isolation

Bannerbear bearer API keys are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped execution access and the raw key never appears in the LLM context window or logs.

Intent-based discovery

Agents search by intent (for example, 'create a marketing image' or 'render a short video') and Jentic returns the matching Bannerbear operations with their input schemas and required template parameters.

Time to first call

Direct Bannerbear integration: 1-2 days for auth, render polling, and asset storage. Through Jentic: under 30 minutes — search, load schema, execute, and handle the returned asset URL.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Choose Placid for PDF output and a different template editor experience; choose Bannerbear for its broader media surface and mature batch collection workflow.

Alternative

Creatomate

Pick Creatomate when video is the primary output and timeline-based composition matters; pick Bannerbear when you need balanced image and video generation in one API.

Use Cloudinary alongside Bannerbear when you need ongoing transformations, optimisation, and CDN delivery of generated assets.

FAQs

Specific to using Bannerbear API API through Jentic.

Why is there no official OpenAPI spec for Bannerbear?

Bannerbear does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Bannerbear 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 Bannerbear API use?

Bannerbear uses HTTP bearer authentication with a project-scoped API key passed in the Authorization header. When called through Jentic, the key is stored encrypted in the Jentic vault and injected at request time so it never enters the agent's context.

Can I generate videos with the Bannerbear API?

Yes. POST /v2/videos with a video template UID and modifications, then poll GET /v2/videos/{uid} until the status is completed. The response includes the hosted MP4 URL ready to embed or download.

What are the rate limits for the Bannerbear API?

Bannerbear enforces rate limits per project plan rather than a single global value. Image renders are typically the most permissive; video and screenshot endpoints have lower concurrent-render limits. Inspect the response headers for current quota and back off when retries are signalled.

How do I render an image through Jentic?

Install the Jentic SDK with pip install jentic, search for 'create a marketing image', and execute the matched POST /v2/images operation with the template UID and modifications. Jentic injects the bearer token, calls Bannerbear, and returns the image_url to the agent.

Does Bannerbear support URL screenshots?

Yes. POST /v2/screenshots with a target URL and viewport options to render a full-page screenshot. Then call GET /v2/screenshots/{uid} to retrieve the hosted image URL once the render completes.
