Anthropic's New API Terms Explained **[SitePoint](https://daily.dev/sources/sitepoint)** · 18 min read · 0 upvotes · 0 comments ## Summary Anthropic's updated API terms restrict using a single company subscription key to authenticate requests on behalf of third-party end users, effectively targeting the 'LLM wrapper' SaaS model. The article explains what is banned (pure API proxies charging subscription fees), what remains compliant (internal tools, AI as an incidental feature, substantial value-add products), and provides a detailed migration guide. The primary compliance path is BYOK (Bring Your Own Key), where each user supplies their own Anthropic API key stored with AES-256-GCM encryption. Code examples in Node.js/TypeScript and Python demonstrate secure key storage and per-user API calls. Additional patterns include multi-provider abstraction using the Vercel AI SDK and customer-owned cloud deployments. OpenAI and Google have similar redistribution restrictions, making this an industry-wide trend rather than an isolated policy change. ## Full article daily.dev links to this article rather than hosting it.
