These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For podcasts announcing a guest, guests sharing "I'm on this show", and hosting platforms that make a card per episode. A long guest_name shrinks to fit, the role and the episode title are clamped to two and three lines, and the show name and link end in an ellipsis. A missing photo becomes initials on a tinted mic-grille pattern; without a cover the seal shows the show's initials; with neither host_name nor host_photo the guest takes the whole photo panel and the cable is not drawn. Wide frames put the photo panel on the left and the text on the right; square and portrait frames put the panel on top, and story and Pinterest frames turn the seam nearly horizontal, guest above host, so both faces keep a wide crop.
Fields
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.

guest_name |
text | The guest's name, the largest text on the card. default: Guest name | Elena Marsh |
guest_title |
text | The guest's role, e.g. Head of Platform at Aurora Audio. | Head of Platform at Aurora Audio |
