Mode: OpenAI-compatible & Anthropic

Any Other Tool (Universal)

Don’t see your tool listed? As long as it can be pointed at a custom base URL and accepts an API key, it works with Nexotao. The principle is always the same: swap the base URL + key, then pick a model.

The universal pattern

OpenAI-compatible (for gpt/grok/deepseek, and Claude, and most tools):

Anthropic-compatible (optional — native Anthropic bodies only):

Examples

from openai import OpenAI
 
client = OpenAI(base_url="https://api.nexotao.com/v1", api_key="sk-nexo-...")
resp = client.chat.completions.create(
    model="gpt-5-mini",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

from anthropic import Anthropic
 
client = Anthropic(base_url="https://api.nexotao.com", api_key="sk-nexo-...")
msg = client.messages.create(
    model="claude-opus-4-8",
    max_tokens=256,
    messages=[{"role": "user", "content": "Hello"}],
)
print(msg.content[0].text)

# OpenAI style
export OPENAI_BASE_URL=https://api.nexotao.com/v1
export OPENAI_API_KEY=sk-nexo-...
 
# Anthropic style
export ANTHROPIC_BASE_URL=https://api.nexotao.com
export ANTHROPIC_AUTH_TOKEN=sk-nexo-...

Cursor & cloud-based tools

Some tools (e.g. Cursor) route requests through their own servers, so a custom base URL may be limited or unavailable. Check whether the tool offers an “Override OpenAI Base URL” / “Custom API key” option. If it does, fill it with the OpenAI-compat pattern above. If not, that tool can’t be used with Nexotao yet.

Troubleshooting checklist

• Unknown model? Match the ID exactly from Models & Pricing.
• 401? Bad/revoked key — create a new one in the dashboard. See Authentication.
• Need the full error list? See the API Reference.
