Hermai Brand API

What is Hermai Brand API?

Hermai Brand API is a developer tool that turns a customer's work email or company domain into a complete brand identity package—logo, colors, description, and a ready-to-apply application theme. Built specifically for B2B SaaS products, it lets you white-label your app so every customer's account looks like theirs from the very first login. One API call at signup returns everything your interface needs to feel personalized, with zero effort from the customer.

Who it's for

• B2B SaaS founders who want every customer's account to feel native from day one, without building a brand settings page or asking users to upload logos.
• Product engineers looking to eliminate manual onboarding steps like logo collection, color picking, and company description entry—replacing them with a single API call.
• Growth teams focused on activation and retention, who need a polished, personalized first-run experience that makes trials feel like production accounts.

Key features

One-call brand retrieval

Send a work email or company domain via POST /v1/brand/retrieve, and Hermai returns the company name, description, logo, and a set of safe, accessible colors. The mailbox name is never stored—only the domain is read, keeping privacy intact.

Ready-to-apply application theme

The response includes an application_theme object with action, on-action, tint, and focus colors, shaped for your theme system. You get contrast-checked colors you've never seen before, with a fallback that keeps your own theme if anything goes wrong.

Source evidence on every field

Each returned value includes a source URL and signal type (like json_ld), so you know exactly where the brand data came from. This makes the API safe by default—no guessing, no unverified scrapes, just traceable data.

Local skill for instant preview

A Claude Code or Codex skill lets you run one command from your app root and preview your own dashboard in five real brands—like HubSpot, Discord, or Casper—before you even get an API key. No account, no setup, just a two-minute test drive.

What stands out

"Zero customer effort. No logo uploads, no brand settings page."

That's the core promise: your customers never have to configure anything, yet their account looks like theirs from the first login. The API handles the entire brand pipeline—logo, colors, description, and theme—in a single call, and it does so with accessible, contrast-checked colors and source evidence on every field. It's not just a logo fetcher; it's a full identity layer that makes every surface of your app feel native to the customer, including prefilled forms and AI assistant suggestions that use the company description to reason contextually.

Worth checking out if…

You're building a B2B SaaS product where personalization at scale matters, and you want to eliminate the manual brand-collection bottleneck. If you're tired of blank placeholders, favicon fallbacks, or customers who never touch settings, Hermai Brand API gives you a free tier of 1,000 brands per month—no card required—to see the difference immediately. It's also ideal if you want to test the experience in your own app within minutes using the local skill, before committing to any integration.
