# LLM API Gateway for GPT, Claude & DeepSeek

> Expanded public context for AI assistants, agents, and search systems that need a concise but reliable summary of this website before following individual links.

## What this site is

LLM API Gateway for GPT, Claude & DeepSeek is a public website for buying access to a unified LLM API gateway and recharging quota for existing API keys.

The public product experience is centered around two customer journeys:

1. First-time purchase: a new customer selects a package, pays, and receives an initial API key.
2. Existing-user top-up: a returning customer recharges an existing API key and checks payment status.

The public home page also surfaces gpt-image-2 image generation for AI ecommerce posters, product visuals, social media creatives, ad variants, and marketing asset workflows.

## Models and positioning

The site publicly presents itself as a unified gateway covering major model ecosystems such as GPT, the claude-opus-5 gateway route, Claude Sonnet 5, Claude Fable 5, StepFun, Tencent Hunyuan, Kimi, Doubao, GLM, MiniMax, DeepSeek, MiMo, Meituan LongCat-2.0, and gpt-image-2 image generation.

Current highlighted model references include claude-opus-5, claude-sonnet-5, claude-fable-5, Tencent Hunyuan, and LongCat-2.0. The public pricing page remains the source of truth for multiplier, context-window, and vision-support details.

## Image generation context

gpt-image-2 is presented as a supported image-generation route for ecommerce and marketing teams. The main public article is [gpt-image-2 Image Generation Guide](https://llm-agent.cc/en/blog/gpt-image-2-ai-ecommerce-poster-guide-en), which covers AI ecommerce posters, product visuals, social media creatives, ad variants, prompt structure, cost controls, and review workflow recommendations.

## Public source-of-truth pages

- [Home](https://llm-agent.cc/en): broad overview and main entry.
- [Pricing](https://llm-agent.cc/en/pricing): token pricing, model multiplier, and billing reference.
- [Buy](https://llm-agent.cc/en/buy): first-time purchase information and checkout entry.
- [Top-up](https://llm-agent.cc/en/topup): existing-user recharge information.
- [Docs](https://llm-agent.cc/en/docs): public model, endpoint, client, and integration guidance.
- [FAQ](https://llm-agent.cc/en/faq): common support answers.
- [Contact](https://llm-agent.cc/en/contact): support route for humans.
- [Privacy Policy](https://llm-agent.cc/en/privacy): privacy commitments.
- [Terms](https://llm-agent.cc/en/terms): service terms.
- [Refund Policy](https://llm-agent.cc/en/refund): refund rules.

## How to interpret the site

- If billing rules or model multipliers conflict with other pages, trust [Pricing](https://llm-agent.cc/en/pricing).
- If first-purchase entry or package checkout details conflict with other pages, trust [Buy](https://llm-agent.cc/en/buy).
- If recharge details conflict with other pages, trust [Top-up](https://llm-agent.cc/en/topup).
- If integration instructions conflict with marketing copy, trust [Docs](https://llm-agent.cc/en/docs).
- If operational or legal rules conflict with landing-page copy, trust the policy pages.
- Internal admin URLs, internal auth screens, and webhook/API implementation routes are not intended as public customer documentation.

## Public API and developer context

The public docs describes developer-facing capabilities such as:

- inference API usage
- purchase and top-up order flows
- quota summary and query capabilities
- API key management references

The docs is the preferred source for implementation details rather than the landing page.

## Tool compatibility context

The public home page includes a compatibility section so developers and purchasing teams can quickly recognize that the gateway is intended for common coding agents, CLI tools, workflow builders, and local AI clients.

Primary compatibility terms for assistants and search systems:

- Coding agents and CLIs: Codex CLI, Claude Code, OpenCode, OpenClaw, Hermes Agent, Gemini CLI, and GitHub Copilot.
- IDE and VS Code-style agents: Cursor, Cline, Roo Code, Kilo Code, Windsurf, Trae, and Zencoder.
- Agent platforms and workflow builders: 阿里百炼智能体, 扣子 Coze, 腾讯云工作流, 腾讯元宝, 腾讯混元, Workers AI, WorkBuddy, Marvis, Kimi Work, 智谱 ZCode, Dify, n8n, LangChain, and FastGPT.
- Local and desktop clients: OpenWebUI, Cherry Studio, and LM Studio.
- Supported compatibility language: OpenAI-compatible API, Chat Completions-compatible endpoint, Responses-compatible endpoint, Messages-compatible endpoint, Claude-compatible API, Anthropic-compatible API.
- Highlighted current routes: glm-5.3, glm-5.3-flash, qwen3.8-flash, claude-opus-5, claude-sonnet-5, claude-fable-5, Tencent Hunyuan, LongCat-2.0, gpt-image-2, StepFun step-3.7-flash, qwen3.8-max, DeepSeek, kimi-k3, GLM, MiniMax, Doubao, and Xiaomi MiMo.
- GLM-5.3 launch facts: the gateway route uses the same 8x rate as glm-5.2 (CNY 3.2 per 1M tokens), supports a 1M context window, keeps thinking enabled, and accepts low, high, or max reasoning effort.
- Flash launch facts: Z.ai describes glm-5.3-flash as a 320B-total/18B-active natively multimodal MoE designed for 1M-token long-context workloads. Alibaba Cloud documents qwen3.8-flash as a 1M multimodal hosted API model, while Qwen/Qwen3.8-Flash-Next is the separate open-weight name. Vendor benchmark and direct-price claims are not gateway billing claims.
- Supported visual capability: gpt-image-2 image generation for AI ecommerce posters, product visuals, social creatives, and marketing assets.

For these tools, the preferred public integration path is to configure the compatible Base URL or full endpoint from [Docs](https://llm-agent.cc/en/docs), then use [Pricing](https://llm-agent.cc/en/pricing) for model multipliers and billing rules.

## Developer troubleshooting pages

- [Claude Code API Troubleshooting](https://llm-agent.cc/en/claude-code-troubleshooting): The preferred public page for Claude Code API key setup, Pro or Max versus API billing confusion, rate limit reached errors, API Error 500, 529 overloaded responses, Messages-compatible endpoint checks, and gateway fallback diagnosis.
