spiderssense.com — One API. Every frontier model.

Documentation

One OpenAI- and Anthropic-compatible gateway in front of every frontier model. Keep your existing SDK — point it at our base URL and authenticate with your key. Billing is prepaid from your balance; create a key in the dashboard to get started.

Base URLhttps://spiderssense.com/v1

API keysk-uno-…Create one in your dashboard, then use it as the API key / bearer token.

Quickstart

One OpenAI-compatible base URL. Send your key as a Bearer token and call any model by its id.

bash

curl https://spiderssense.com/v1/chat/completions \
  -H "Authorization: Bearer sk-uno-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5",
    "messages": [{ "role": "user", "content": "Hello!" }]
  }'

OpenCode

Add a provider to your opencode.json (project root or ~/.config/opencode/), then pick a model with /models. The attachment + modalities flags tell OpenCode the model accepts images.
