Concepts
Short explanations of the terms the directory and guides use, from what a brand is to logo variants, attribution rules, credits, rate limits and caching.

The directory and the guides use these terms. Each page is short and answers one question.
- What is a brand, to an API?
A brand is its identity, guidance and files. Lookup APIs return part of the identity, DAM APIs return files, and agentic brand APIs return all three per task.
- Logo, symbol, icon and wordmark
A company usually has several versions of its logo, and lookup APIs name them differently. What each term means, where to show which, and the formats returned.
- Who keeps brand data current?
Lookups re-read a company's website every few months, DAMs are kept current by its team, and Rainbrand applies edits you approve. How each reports changes.
- Logo use, attribution and trademarks
Some logo APIs require a visible link on their free plans, and none gives you rights to the logos. What each provider asks for, and what the logo's owner keeps.
- Credits, rate limits and caching
How each brand API counts a request, how fast you can call it and what you may store. These details decide your bill more than the headline price does.
