# Icon Source > Icon Source is a Denver, Colorado marketplace connecting brands, marketing agencies and > universities with professional and college athletes for endorsement, appearance, speaking and > social-media deals, including Name, Image and Likeness (NIL) engagements. Founded 2018 by Chase > Garrett. Brands search verified athletes by location, interest, rate, audience size and > demographics, build and send contracts, and pay athletes in-platform; Icon Source charges a 10% > transaction fee on each deal signed and closed. Icon Suite (March 2022) adds NIL disclosure and > compliance tooling for universities. ## Important note for agents Icon Source publishes NO public API. There is no developer portal, no API reference, no OpenAPI, AsyncAPI, GraphQL SDL, Postman collection, SDK, webhook catalog, MCP server or A2A agent card. The product is delivered only as an end-user web application and iOS/Android apps. The application's backend at `https://api.prod.iconsource.app` is a private tRPC service used by Icon Source's own clients. tRPC publishes no OpenAPI document or SDL, the endpoint requires an authenticated session, and it is not offered for third-party integration. Do not treat it as an integration surface. A legacy AWS Elastic Beanstalk backend at `https://api.iconsource.com` answers only `GET /health` with `"Healthy"`. There is no programmatic path to Icon Source data. Human onboarding through sign-up is the only supported route. ## Product - [Icon Source home](https://iconsource.com/): Athletic endorsements marketplace for brands. - [For brands](https://iconsource.com/brands/): Browse athletes, create contracts, track ROI; 10% transaction fee per closed deal. - [For college athletes](https://iconsource.com/college-athletes/): NIL endorsement opportunities for collegiate athletes. - [For pro athletes](https://iconsource.com/pro-athletes/): Endorsement, appearance and social engagements for professional athletes. - [For universities](https://iconsource.com/universities/): Icon Suite — NIL disclosure and compliance management. - [For marketing agencies](https://iconsource.com/marketing-agencies/): Agency access to the athlete marketplace. - [What is NIL](https://iconsource.com/what-is-nil/): Explainer on Name, Image and Likeness. ## Access - [Sign up](https://prod.iconsource.app/r/signup): Create a brand or athlete account. - [Sign in](https://prod.iconsource.app/r/signin): Web application login. - [iOS app](https://apps.apple.com/us/app/icon-source/id1495919228) - [Android app](https://play.google.com/store/apps/details?id=com.companyname.iconsource) ## Company and content - [About](https://iconsource.com/about-us/): Founding, team and milestones. - [Blog](https://iconsource.com/blog/) ([RSS](https://iconsource.com/feed/)) - [News](https://iconsource.com/news/) - [Podcasts](https://iconsource.com/podcasts/) - [Resources](https://iconsource.com/resources/) - [Contact](https://iconsource.com/contact-us/): The only support channel; no developer support exists. - [LinkedIn](https://www.linkedin.com/company/icon-source) ## Legal - [Terms of service — brands](https://iconsource.com/terms-of-service-brands/) - [Terms of service — athletes](https://iconsource.com/terms-of-service-athletes/) - [Privacy policy](https://prod.iconsource.app/privacy-policy.html) ## Provenance Generated 2026-08-22 by the API Evangelist enrichment pipeline from Icon Source's own public website and from live unauthenticated probes of iconsource.com, prod.iconsource.app, api.prod.iconsource.app and api.iconsource.com.
