5 templates, each a real render from the API. Change the text, then render one with an API call, a signed URL or a batch from a spreadsheet.
Course completions, graduations, certifications and awards. Each template takes the recipient, the course or award, the date and a signature line; render it as an image to share or as a one-page vector PDF to print.
A certificate on paper with a double border, the recipient's name in serif italics, the course, date, issuer and a seal.
A round portrait wearing a drawn mortarboard on the school colour, with the class year outlined large behind the name and degree.
A credential card: badge on a halo with a check mark, the certification name, holder, skill tags and the verify link in mono.
A medal on striped ribbons with the placement on its banner, then the award, the recipient in large type and the issuer with the year.
A shareable quiz or assessment result: the score in a scalloped accent seal, the result name as the headline, a short description and ten-cell trait meters.
Send the template slug, your text and the size, and the image URL comes back in seconds. Every template lays itself out for every size preset (og 1200×630, square 1080×1080, portrait 1080×1350, story 1080×1920, pinterest 1000×1500, youtube 1280×720), so `sizes` gives you several formats from one request.
