Look up a brand's logos, colors, fonts and company data by domain, ticker, ISIN, crypto symbol or card transaction with Brandfetch.
Brandfetch ships in the w6w first-party pack. It declares 9 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.brandfetchBrandfetch turns a company identifier into its brand: logos and icons in SVG, PNG and WebP, the color palette, fonts, imagery, social links, description and company facts (industry, employees, founding year, headquarters, ticker and ISIN).
A workflow can look a brand up by domain, website URL, email address, brand id, stock or ETF ticker, ISIN or crypto symbol, search brands by name, read a brand’s narrative context (positioning, voice and visual style) as JSON or Markdown, and resolve a raw card-transaction label to the merchant behind it. Account usage against the plan’s credit allowance is readable for free.
The connection holds a Brandfetch API key, sent as a bearer token. An optional Brand Search client ID can be added; it is sent only on name searches. The Logo CDN (cdn.brandfetch.io) is not an action: it serves images straight from a URL and needs no call.
Three routes to the same 9 actions. The Workflow tab is generated from Brandfetch's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
get-brand Get a brand's logos, colors, fonts, imagery, links and company data from a domain, website URL, email address, brand ID, ticker, ISIN or crypto symbol. Billed per call (a 404 too).
get-brand-by-domain Get brand data for a domain, with no ticker or crypto-symbol ambiguity. Email addresses and website URLs are refused by this route; use Get Brand for those.
get-brand-by-ticker Get brand data for a listed company from its stock or ETF ticker.
get-brand-context Get a narrative brand profile for a domain: identity, positioning (value proposition, audience, products) and brand voice and visual style, as structured JSON or Markdown ready for an LLM prompt. Billed per call.
get-brand-from-transaction Resolve a raw card or bank transaction label (e.g. "AMZN Mktp US*2K4") to the merchant's brand: name, domain, logos and company data. Billed per call.
get-viewer Read the connected API key's name, organization and credit usage (used / quota) for the current billing period. Free: it never consumes credits.
search-brands Search brands by company name; returns the brand ID, name, domain and icon of each match, best first. Feed a hit's domain to Get Brand for the full profile.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Brandfetch's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Brandfetch, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Brandfetch. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.brandfetch#get-brand",
"input": {
"identifier": "<identifier>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Brandfetch connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Brandfetch's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Brandfetch itself is MIT, and the runtime that executes it is source-available (FSL).
Brandfetch declares its own checks, so its health is a property of the app rather than something the host guesses at.
Status of the Brand API, Brand Context API and Search API on status.brandfetch.io (Better Stack). Other resources are shown but do not drive the verdict.
Unauthenticated GET /v2/viewer. Brandfetch's JSON `Unauthorized` refusal passes: it proves the application is answering.
Credits used vs the plan allowance, from the free GET /v2/viewer.
