Bot Butcher is an API designed to help developers stop contact form spam bots on websites by automatically classifying incoming messages using artificial intelligence. When a visitor or automated system submits a message through a website’s contact form, the message can be sent to the Bot Butcher API along with contextual information such as the domain. It uses a fine-tuned large language model to analyze the content and determine whether the message is spam or legitimate within the context of the website’s topic. The API then returns a JSON response indicating the classification, allowing developers to automatically block spam or pass valid messages to the intended recipient or CRM system. This enables websites to filter unwanted bot traffic before it reaches inboxes, significantly reducing the amount of spam that site owners must handle.
