domain | path | ✅ | The company domain (e.g., stripe.com, apple.com). With or without www.; protocol is ignored if included. |
Content-Type header.
No authentication required. No
Authorization header, no API key, no signed URLs. Hotlink directly from <img src> in production.How it works
Lookup by domain
Provide any company domain in the URL path. Pubrio resolves the canonical brand and returns its logo from a continuously refreshed source set.
CDN-delivered
Logos are cached at the edge. First request warms the cache; subsequent requests serve from the closest POP with sub-100ms latency.
No authentication
Public endpoint. Embed directly in
<img src> tags, marketing sites, prospecting tools, dashboards, or browser extensions.Graceful fallback
Unknown or unresolvable domains return a neutral placeholder rather than a broken image — your UI never shows a missing-asset icon.
Examples
stripe.com
airbnb.com
shopify.com
github.com
Common use cases
CRM and prospecting UIs
Show logos next to company records in your CRM, sales tooling, or BI dashboards — no need to upload, store, or maintain a logo asset library.
Email signatures and sequences
Embed the recipient’s company logo in personalized outbound — every send fetches the freshest logo from the CDN.
Investor dashboards and portfolio pages
Render a company grid by domain. Works for public, private, early-stage, or international companies that aren’t in mainstream stock-image sets.
Marketing pages and case studies
Customer logo walls, integration grids, “trusted by” sections — fed straight from a list of domains.
Migrating from another logo provider
If your existing logo URLs follow thehost/{domain} pattern, switching to Pubrio is a one-line find-and-replace.

Unknown or unresolvable domains return a neutral placeholder image rather than a 404 — your UI stays clean. If you need to detect “no logo found” programmatically, inspect the response headers.
What image format is returned?

Pubrio returns the highest-quality format available for each brand (typically PNG with transparency). The
Content-Type header reflects the actual format served.Are there rate limits?
Are there rate limits?
The endpoint is designed for in-page hotlinking and high-volume CDN delivery. There are no per-IP rate limits for normal browser usage. Server-to-server bulk crawling is subject to fair-use throttling — if you have a high-volume backend use case, reach out.
