↔

Two API shapes, one key

Point OpenAI or Anthropic clients at NexoAI. The same issued key and wallet work with both wire formats.

Prepaid, jamais surprise

Start with $5 in free credit, top up in USD, and use hard budget caps instead of an open-ended subscription.

◈

Flagship catalog

Reach GPT, Claude, Gemini, Grok, DeepSeek, and Qwen families through one developer-friendly gateway.

⏱

Limits you control

Give each named virtual key its own requests-per-minute, tokens-per-minute, and total budget caps.

{}

Drop-in tooling

Configure Claude Code, Codex, or any OpenAI-compatible client with familiar environment variables and SDKs.

◉

No subscription

Pay by card, top up only when you want to, and keep usage and model pricing clear in USD.

Deux variables. Zéro SDK.

Use the client you already have. Set the matching base URL and your NexoAI key, then make a request.

Claude Code / AnthropicCodex / OpenAI

bash

export ANTHROPIC_BASE_URL="https://api.nexoai.dev"
export ANTHROPIC_AUTH_TOKEN="sk-your-key"

bash

export OPENAI_BASE_URL="https://api.nexoai.dev"
export OPENAI_API_KEY="sk-your-key"

The variable names change; the base, issued key, and prepaid wallet do not. Continue with the five-minute guide or jump directly to CLI setup.

One endpoint, six model families

Choose the model that fits the work instead of maintaining six vendor accounts. The catalog includes claude-sonnet-5, claude-opus-4-8, gemini-3-pro-preview, grok-4.5, deepseek-v4-flash, and qwen3-coder-next.
