LogoRouter API
Deliver logos, palettes, enrichment JSON, batch flows, and OpenAPI-backed contracts across our global CDN and REST edge.
LogoRouter bundles CDN image delivery, REST JSON enrichment, Stripe-backed metering, and a living OpenAPI 3.1 contract on one edge platform.
What you get
- CDN images — Embed
https://img.logorouter.com/{domain}?size=128…anonymously for ≤128 px demos (publishable?token=keys unlock richer embed policies when your plan permits). - REST mirrors —
GET /api/{domain}honours the exact tuning matrix (size,format,retina,theme,fallback,greyscale,refresh). - Brand palettes —
GET /api/colors/{domain}is secret-only JSON for CRM / UI tinting pipelines. - Company intelligence —
GET /api/intelligence/{domain}packages AI-assisted firmographics for server-side augmentation. - Discovery + kit routes — Search / ticker / crypto / ISIN helpers, describe/meta/brand payloads.
- OpenAPI-first — Endpoint index links the machine-readable surface that CI should pin.

Authentication recap
Secrets (lm_live_* · lm_test_*) authenticate server jobs. Publishable derivatives power safe <img> embeds (?token=) yet reject JSON intelligence/color routes outright.
Pick the right key for the surface
Server jobs use secret keys (Authorization: Bearer …). Public <img> tags
use a publishable key on the CDN URL (?token=…). JSON enrichment routes
(/api/colors, /api/intelligence) only accept secrets.
