Logo URL

https://logos-api.apistemic.com/domain:stripe.com

How to Build It

1
Use the customer's or vendor's domain from your billing data.
2
Add format=png: many PDF generators cannot read WebP, our default format.
3
Download the logo once per document, so that the PDF does not depend on the URL later.

Code Examples

Copy and adapt them, the logo URLs work as they are.

Python: logo for a PDF

def fetch_logo_png(domain: str) -> bytes:
    response = requests.get(f"https://logos-api.apistemic.com/domain:{domain}", params={"format": "png"})
    response.raise_for_status()
    return response.content
