🧠For Claude Code users

Claude Code, on a gateway that won't lie to you.

One env var points claude-code at api.voltai.one. Same SDK, same /v1/messages protocol, byte-identical responses β€” with USD billing, invoices, and a daily parity benchmark you can audit.

Why VoltAI instead of a CN Claude-Code reseller

πŸ’΅

USD billing, real invoices

We charge in USD, issue USD invoices, remit taxes from a Wyoming LLC. No CNY spread, no opaque credit system, no WeChat top-up.

πŸ“Š

Daily parity benchmark

We publish MMLU-Pro / GSM8K / HumanEval raw scores every 24h at /integrity. If Ξ” vs. Anthropic direct is > 1.5%, you get a full refund.

πŸ”€

One model name β†’ one upstream

claude-opus-4-7 on VoltAI always routes to official Anthropic. No silent substitution to a cheaper model, no quantization switching, ever β€” written into our Terms of Service.

Every request logged, exportable

CSV export of every call: request id, model, tokens in/out, cost, latency, upstream region. Your auditors will love you.

Three commands, thirty seconds

claude-code already speaks the Anthropic wire protocol. We host that same endpoint with one URL change.

  1. 1

    Get an API key

    Sign up at console.voltai.one, generate a server key. First $5 is on us.

  2. 2

    Point claude-code at VoltAI

    Two env vars. Claude Code's CLI picks them up automatically.

    # One-time setup: point Claude Code at VoltAI
    export ANTHROPIC_BASE_URL="https://api.voltai.one"
    export ANTHROPIC_AUTH_TOKEN="sk-voltai-..."      # from console.voltai.one
    
    # Persist across shells
    cat >> ~/.zshrc <<'EOF'
    export ANTHROPIC_BASE_URL="https://api.voltai.one"
    export ANTHROPIC_AUTH_TOKEN="sk-voltai-..."
    EOF
    
    # Then just use it
    claude-code
    bash
  3. 3

    Verify the wiring

    Hit /v1/messages with a sanity prompt. If it replies "voltai-ok", you're routed through VoltAI.

    curl -s https://api.voltai.one/v1/messages \
      -H "Authorization: Bearer $ANTHROPIC_AUTH_TOKEN" \
      -H "anthropic-version: 2023-06-01" \
      -H "content-type: application/json" \
      -d '{
        "model": "claude-sonnet-4-6",
        "max_tokens": 64,
        "messages": [{"role":"user","content":"reply with: voltai-ok"}]
      }'
    # expect: "voltai-ok"
    bash
  4. 4

    (Optional) persistent config

    If you prefer a config file over env vars, drop this in ~/.claude-code/settings.json.

    // ~/.claude-code/settings.json (optional)
    {
      "api": {
        "baseURL": "https://api.voltai.one",
        "authToken": "sk-voltai-..."
      },
      "defaultModel": "claude-sonnet-4-6"
    }
    json

Common questions

Is this a modified Claude? A fine-tune?+

No. VoltAI is a transparent passthrough β€” your request hits Anthropic's official endpoint, the raw response comes back to you byte-identical. We do not inject prompts, we do not rewrite outputs, we do not train on your data. See /integrity.

How does billing work? Is this a Claude subscription?+

It's metered API usage, not a subscription. You pay per token β€” upstream Anthropic rate + 5% gateway fee, billed monthly in USD. No minimum, cancel anytime, no OAuth handshake with your Anthropic account.

What happens if Anthropic raises prices?+

We mirror upstream rates within 24 hours and email you first. We never mark up beyond the published gateway fee.

Can I use my own Anthropic key (BYOK)?+

Enterprise plans support zero-trust BYOK: you configure your own Anthropic key, VoltAI handles auth/metering/rate-limiting but never sees the model output. Contact sales@voltai.one.

What if your parity check fails?+

If the daily /integrity snapshot shows Ξ” > 1.5% vs. Anthropic direct on any benchmark, we publish the incident within 24h and refund your full billing period for affected models. No arguing, no case-by-case β€” it's in the ToS.

The gateway Claude Code deserves
