Logo.dev
Create browser-ready company, stock, and crypto logo URLs from a Swarmz project
Connect Logo.dev when a project needs current company, stock, or crypto logos without maintaining its own asset library. The connector validates the target and returns a browser-ready PNG URL.
Logo.dev uses a shared project connection with a publishable key. The returned image URL contains that publishable key by design; do not use a private secret in this connection.
Availability
A Swarmz administrator must show Logo.dev under Platform config > Integrations. Logo.dev does not require a Swarmz OAuth application.
Connect Logo.dev
- Create a project in Logo.dev and copy its publishable API key. Logo.dev explains publishable and secret keys.
- In the Swarmz project, open Settings > Integrations and select Logo.dev.
- Select Add connection, paste the publishable key into API key, and select Save connection.
Swarmz verifies that the key can return an image. The key is still stored as a connection credential, but logo_url may place it in browser image markup because it is explicitly publishable.
Available operations
| Operation | What it does | Limit per minute |
|---|---|---|
logo_url | Returns a validated browser-ready PNG URL for a domain, ticker, or crypto symbol | 60 |
Domains must be real hostnames such as example.com. Tickers and crypto symbols accept short letters, numbers, dots, and hyphens. Choose a size from 16 to 512 pixels and an optional light or dark theme.
Ask the AI to use Logo.dev
- “Show company logos beside these customer domains and use a neutral fallback when a logo is unavailable.”
- “Build a stock watchlist with 64-pixel ticker logos.”
- “Add light and dark logo variants to this customer grid.”
Logo.dev is for displaying provider-hosted logos. Download and store an asset yourself when the project needs an immutable, licensed copy rather than a live image URL.
Verify Logo.dev
- Request a logo for a known company domain.
- Open the returned URL in the generated app and confirm the expected image.
- Test one stock ticker and one crypto symbol.
- Test the missing-logo fallback in the UI.
Troubleshoot and recover
If setup fails, confirm you copied the publishable key, not an unrelated project secret. If one company is missing, try its canonical website domain; a company name is not a domain.
To rotate the key, replace it in the Swarmz connection and verify one known logo before disabling the previous key. To disconnect, select Remove in Swarmz and revoke the key in Logo.dev.
