Which kind of brand API do you need?

Choose by the job, not by the feature list. Brand APIs do one of three jobs, and the products in each do that job well and the other two poorly.

You need	Kind of API	Start with
A company's logo beside its name	One-off lookup	Logo.dev, Brandfetch
A signup form filled in from a work email	One-off lookup	Brandfetch, Context.dev
A customer's approved files, with their rights	File management (DAM)	The API of the DAM they use
Agents making new work for the same brands	Agentic brand work	Rainbrand

One-off lookups

Use one when you need a company's logo, colours or name and that company isn't your customer: a logo on each row of a CRM, a prospect's colours on a sales deck, a signup form that fills itself in.

You send a domain and get back what the company shows in public. Nobody at that company signs up or approves anything. The data is as current as the provider's last crawl, and it stops at the public face: no voice, no rules, nothing the company hasn't published.

Brandfetch, Logo.dev, Context.dev, LogoKit and Hunter do this job.

File management (DAM)

Use one when a company keeps its approved files in a digital asset management (DAM) system and your product needs those exact files: the current logo set, approved product photos, licensed images that expire.

Your code calls the DAM's API with that company's permission. It returns files and their metadata, and in some products guideline pages. Pricing follows the company's own plan, and some APIs need particular plans. Each integration reaches the customers of one DAM.

Frontify, Bynder, Brandfolder, Canto and Cloudinary do this job.

Agentic brand work

Use one when agents make new work for the same brands again and again: posts, pages, emails, images, decks. The brands can be your own, your clients' or your customers' inside your product.

For that, an agent needs more than a logo or a folder of files. It needs the rules that apply to this task, the exact values, the files to place instead of redrawing them, and a check of what it made. When the brand changes, the next task should use the change without anyone uploading a new PDF.

Rainbrand does this job. You add a brand from its website, guide and files; agents ask for the guidance and files for each task and for a review of the result; changes are prepared as edits you apply. Its entry also lists what it doesn't do.

Can you use more than one?

Yes. They do different jobs, so they don't compete inside one product. A lookup can greet a new customer with their logo at signup while an agentic brand API guides the work you make for them, and the files can come from their DAM.
