Keyway Integration Guide

A single db_sk_ key lets you connect Claude Code (and any OpenAI/Anthropic SDK client) to Keyway, routing requests across DeepSeek / MiniMax / Volcengine Ark / Zhipu GLM / Qwen and more — just pick a model alias, no config changes needed.

1. How it works

Keyway is a routing gateway. Clients send requests using OpenAI or Anthropic protocol; Keyway resolves the model alias to the configured upstream provider and forwards:

• OpenAI protocol clients → POST /v1/chat/completions → Keyway routes to an OpenAI-compatible upstream.
• Anthropic protocol clients → POST /v1/messages → Keyway routes to an Anthropic-compatible upstream.

All upstream real API keys are stored encrypted on the Keyway server. Clients only hold a single db_sk_ self-issued key.

2. Keyway endpoints

3. Connecting Claude Code

Step 1: Create a self-issued key

Log in to the admin UI, open a group, scroll to "Self-issued API Keys", create a key. The plaintext db_sk_… is shown once (you can re-retrieve it later as admin).

Step 2: Configure Claude Code

Use project-level config. Create .claude/settings.local.json in your project root:

{
  "env": {
    "ANTHROPIC_BASE_URL": "http://localhost:9233",
    "ANTHROPIC_AUTH_TOKEN": "db_sk_your-key-here",
    "ANTHROPIC_MODEL": "deepseek-v4-pro",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-v4-pro",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "deepseek-v4-pro",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "deepseek-v4-pro"
  }
}

Step 3: Verify

Test with curl first (bypasses Claude Code for easier debugging):

curl -X POST http://localhost:9233/v1/messages \
  -H "Authorization: Bearer db_sk_your-key" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek-v4-pro","max_tokens":16,"messages":[{"role":"user","content":"Reply with OK."}]}'

Should return {"id":"msg_…","type":"message","content":[{"type":"text","text":"…"}],…}.

4. Connecting OpenAI SDK (Python)

from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:9233/v1",
    api_key="db_sk_your-key-here",
)

resp = client.chat.completions.create(
    model="deepseek-v4-pro",  # your route alias
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)

For streaming, add stream=True. The /v1/models endpoint lists all enabled route aliases as models.

5. Upstream providers

6. Troubleshooting

404 "model not found"

Alias is misspelled, route is disabled, or provider is disabled. Check the admin UI or run "E2E Test".

404 "model is bound to X provider, not openai/anthropic"

Your route's provider protocol doesn't match the client's protocol. An OpenAI client needs an OpenAI-protocol provider; an Anthropic client needs an Anthropic-protocol provider.

502 upstream error

Check the request logs in the admin UI — they show the upstream status code and error message. Common causes: invalid upstream API key, wrong model name, or the model doesn't support the requested feature.

Claude Code can't connect

• Ensure ANTHROPIC_BASE_URL has no trailing slash.
• Use ANTHROPIC_AUTH_TOKEN not ANTHROPIC_API_KEY.
• Make sure all ANTHROPIC_DEFAULT_*_MODEL values are valid aliases.
