Introduction

Consistent company logos for apps, spreadsheets, and documents.

Brandmarks provides company logos and square marks on consistent canvases, with matching color and white variants. Start with the catalog to check whether your company is included. Coverage is a curated collection, not every business on the web.

The API is in invite-only beta. Request access; keys are issued manually. There is no self-service dashboard yet. The examples use the current Worker hostname; a dedicated API hostname is not configured in this repository.

What is available today?

Ticker and domain lookup, company search, company metadata, SVG and PNG assets, and four API themes are implemented. Webhooks, ISIN/crypto/exchange/index lookup, team administration, and self-service account deletion are not available. These pages describe current behavior, not promised delivery dates.
