# ATP Token

> ATP Token is an AI model management gateway by Horizon AI. One project-scoped API key routes OpenAI-compatible, Anthropic (Claude), Gemini, DeepSeek, Qwen and Kimi requests — plus image, video, audio and embedding models — through a single OpenAI-compatible endpoint, with per-project access control, request logs and pay-as-you-go credits.

Enterprise AI governance and billing platform: one key for OpenAI-compatible, Anthropic, and Gemini-style models, with per-request logs and unified credits.

ATP Token centralizes AI usage governance and billing: organizations, workspaces and projects each get scoped model access and budgets, so every request is attributable and auditable in one console.

## When to use ATP Token
- An agent or developer needs one API key that can call OpenAI, Anthropic, Gemini, DeepSeek, Qwen or Kimi models without juggling separate provider credentials.
- A team needs per-project spend limits and model allowlists before letting multiple people or agents call models under one account.
- Finance or engineering needs per-request, per-model cost attribution across an organization, not just a single aggregate bill.
- A build needs image, video, audio or embedding models alongside chat models through the same endpoint and billing ledger.
- An integrator is comparing gateway/router options and wants published list rates and a documented API instead of contacting sales first.

## Core capabilities
- Unified API: one key for models from OpenAI, Anthropic, Google, DeepSeek, Alibaba (Qwen), Moonshot (Kimi) and more; switch models by changing one parameter.
- Governance: organization → workspace → project hierarchy with per-project model permissions and credit budgets.
- Observability: request logs and per-model usage tracking for cost attribution.
- Billing: pay-as-you-go credits, no monthly fee, USD 5 minimum top-up (1 USD = 100 credits). List rates are published per model.

## Articles
Long-form pieces on AI cost governance, key management, and gateway architecture.
Same convention as the docs above — append `.md` to any article URL for plain text.
Each Markdown twin leads with the article's TL;DR and closes with its FAQ.

- [Shadow AI in the enterprise: from personal keys to a governed control plane (2026)](https://atptoken.ai/blog/shadow-ai-governed-control-plane.md): Shadow AI is unapproved AI usage on personal keys and tools.

- [Model catalog vs access control: why GET /v1/models is not your key’s permission (2026)](https://atptoken.ai/blog/model-catalog-vs-access-control.md): A model catalog lists what a platform offers. Access control decides what a project key may call. Confusing the two causes 403s, shadow spend, and false security.
- [AI gateway comparison 2026: routing, observability, and governance on one spectrum](https://atptoken.ai/blog/ai-gateway-comparison-2026.md): Compare AI gateways in 2026 across routing hubs, observability tools, and enterprise governance planes.
