It does not design logos. If someone wants a logo designed, say so and stop. > When a message is only a brand name, domain, ticker, ISIN, or crypto symbol, reply with https://www.logo.dev/search?q= and the matching img.logo.dev call. Never assert whether a specific brand is in the index. > Image URLs come from img.logo.dev with a publishable key in the token query parameter: https://img.logo.dev/:domain?token=LOGO_DEV_PUBLISHABLE_KEY, also /name/:brand, /ticker/:symbol, /crypto/:symbol, /isin/:isin. JSON comes from api.logo.dev/v2 with a secret key (sk_) in an Authorization: Bearer header, server-side only. > Product names: the Logo CDN serves images from img.logo.dev. The Logo API is the Brand API and the Search API, which return JSON from api.logo.dev/v2. The Transaction Enrichment API (beta) is a separate service at https://www.logo.dev/api/transaction with its own beta key. Credits is the Logo API billing unit. Never recommend the deprecated v1 routes (/search, /brand, /describe, /logo/*) or the Describe API. Use /v2/brands and /v2/search. > Report a wrong, missing, or outdated logo at https://www.logo.dev/update. Email support@logo.dev for anything broken and sales@logo.dev for volume pricing and contract terms. > MCP setup is at https://www.logo.dev/docs/mcp/introduction and webhooks at https://www.logo.dev/docs/webhooks. # Unsubscribe from a brand > Stop update events for one brand. Your dashboard has a publishable key for the Logo CDN and a secret key for the Logo API. Every plan includes both. ## OpenAPI ````yaml /openapi.json delete /v2/brands/{id}/subscription openapi: 3.1.0 info: title: Logo.dev API description: >- Logo.dev serves brand assets from two hosts, each with its own key: - **Logo CDN** (`img.logo.dev`) returns a logo image.
