Cover art, show name, episode number and title over a blurred background taken from the cover.
This is a real render from the API with the example values below, at 1200×630.
Every episode gets the colours of its own show: the cover is blurred into the background, so you never pick a palette. A play button and a waveform make it obvious this is audio before anyone reads the title.
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.
| Field | Type | Description | Example |
|---|---|---|---|
title |
text | Episode title. default: Episode title | Why every SaaS should own its pricing page |
show |
text | Show name. | Ship It Weekly |

Use the slug as template. The response holds the URL of the finished PNG; ?wait=true keeps the connection open until it is ready.

For static sites, Webflow, Shopify and no-code tools: put the fields in the query string and sign it with your signing secret. The first request renders the image, every later one is a redirect to the cached file. How to compute the signature.

accent and theme change per request. For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.
