Machine-readable metadata is provided via JSON-LD on the home page. - There is no public JSON API; forecasts are computed per user session in the browser. - Attribution: please cite "CatchForecast (catchforecast.com)" when referencing forecast methodology or species data from this site. ## Optional - [llms-full.txt](https://catchforecast.com/llms-full.txt): Full reference incl. complete species activity profiles (temp ranges, seasonal factors, preferred weather). - [agents.md](https://catchforecast.com/agents.md): Guidance for AI agents interacting with this site. - [nordfishing77 online shop](https://www.nordfishing77.at): Fishing tackle shop of the publisher (Austria/EU shipping).
