A service that supplies company logos through image URLs based on a company's web domain. The image can be placed directly in a webpage, app, email, spreadsheet, or similar interface.

Use it for company-logo displays, logo walls, CRM avatars, merchant icons, directories, transaction lists, and other interfaces that need logos by domain.

It avoids exposing a private brand-service API key in browser code and avoids parsing a larger API response just to display an image. Logos can be loaded from a CDN as raw image data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00057	$0.00933
Opus 5	$0.00028	$0.00466

Security

Grade A, and why

logolink scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context.dev Logo Link

Logo Link delivers company logos via CDN. Pass a front-end-safe publicClientId and a domain; the URL returns raw image bytes (no JSON, no API key).

Do not use the brand API or MCP from browser/client code for logos. Use Logo Link instead.

When to use

User wants logos in a UI, landing page, CRM, directory, or transaction list
User asks to "dynamically fetch/display company logos by domain"
High-volume logo rendering where ctxt_secret_ keys must stay server-side
User needs a simple <img src="..."> instead of parsing brand.logos[]

Use the brand API (see context-dev skill) when you need stored logos, multiple variants (light/dark/icon), or colors alongside the image.

Step 1 — Get the Public Client ID

Sign up at context.dev/signup if needed (free tier: 10,000 Logo Link requests/month).
Copy the Public Client ID from context.dev/dashboard/logolink. Keys look like brandLL_xxx.
Prefer an env var the codebase already uses, e.g. NEXT_PUBLIC_LOGOLINK_KEY or VITE_LOGOLINK_PUBLIC_CLIENT_ID. Never put a private Context.dev API key in client code.

Step 2 — Restrict referring domains

In the Logo Link dashboard, Edit Restrictions and allow only domains that embed the image (e.g. *.example.com, localhost:3000). The publicClientId is safe in frontend code only when restrictions are set.

Step 3 — Build the URL

https://logos.context.dev/?publicClientId=MY_PUBLIC_CLIENT_ID&domain=TARGET_DOMAIN

Replace MY_PUBLIC_CLIENT_ID with the user's ID (or env var).
Replace TARGET_DOMAIN with the company domain variable (bare domain, e.g. stripe.com).
Optionally add theme=light for a dark logo on a light UI or theme=dark for a light logo on a dark UI.
GET and HEAD only. Response is the image file; Content-Type is image/png, image/svg+xml, etc.
24-hour Cache-Control on the response. Browser/CDN caching is expected.
Fallback: if no logo is found, Logo Link returns a generated SVG monogram — <img> tags never 404.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
