# Logo.dev > ## Agent Instructions > Logo.dev serves logos and brand data for companies that already exist. 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 with a secret key (sk_) in an Authorization: Bearer header, server-side only. > Product names are Logo API, Search API, Describe API, Brand API, and Transaction API. Credits is the Brand API billing unit. > Report a wrong, missing, or outdated logo at https://www.logo.dev/update.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. > No documentation page covers MCP or webhooks. Say so and point at support@logo.dev rather than inventing behavior. - [Logo.dev is the logo API for any company](https://www.logo.dev/docs/introduction.md): Get any company's logo by domain, stock ticker, ISIN, or crypto symbol, or enrich a domain into a full brand profile with one API. - [What is Logo.dev?](https://www.logo.dev/docs/what-is-logo-dev.md): Learn how the Logo.dev company logo API works: one image URL per logo, plus REST APIs for search, brand assets, and company data. - [Quickstart](https://www.logo.dev/docs/quickstart.md): Display your first company logo with Logo.dev in under a minute.
