  description: >-
    The HASP Public AI API is the regulated-AI substrate for healthcare and
    other

    regulated industries — identity, policy, audit, compliance, and PHI handling

    for AI inference, exposed via two surfaces:


    - **Native (`/v1/ai/*`)**: HASP-native chat with full event taxonomy, run
    lifecycle,
      and PHI metadata.
    - **Anthropic-compat (`/v1/messages`)**: Drop-in replacement for
    `@anthropic-ai/sdk` —
      change only `baseURL`. All Gateway compliance checks (BAA, credits, PHI policy) apply.

    All requests require an API key (`Authorization: Bearer
    hasp_api_live_<key>`). See

    [Authentication](https://docs.usehasp.com/ai-api/authentication) for key
    management.
