# Spamadin > Server-side spam detection for website contact forms and comments. English API field names are stable across all website languages. - [Integration reference](https://spamadin.com/llms-full.txt): authentication, checks, bulk checks, browser evidence, corrections, privacy and opt-in examples. - [OpenAPI 3.1](https://spamadin.com/openapi.json): request schemas generated from the API validators. - [Developer documentation](https://spamadin.com/docs): human-readable guide and WordPress setup. - [WordPress plugin](https://spamadin.com/downloads/spamadin.zip): installable plugin with a reusable account API key and automatic website registration. - [Privacy policy](https://spamadin.com/privacy) - [Terms](https://spamadin.com/terms) Keep API keys server-side. Do not send passwords, payment details, attachments, unrelated visitor data, or AI provider credentials. Never discard a message because of an HTTP/network error or a review verdict. Improvement example sharing is a separate explicit opt-in, never a requirement for reporting a correction. Website allowances: Starter includes 1 enabled website, Growth includes 5, and every Scale volume includes unlimited websites. Scale has no website-count storage cap. Monthly check allowances remain shared account-wide; website blocks, authentication and rate limits always apply.
