I still remember the exact moment my editor froze on a refactor of a 3,000-line Python module. Continue.dev was throwing ConnectionError: Request timeout after 30000ms while trying to reach Anthropic directly from Shanghai, and every retry ate another 30 seconds. After switching Continue.dev's provider to HolySheep's OpenAI-compatible relay, my tab completion for Claude 4.7 came back in under 50ms and the timeout errors vanished entirely. This guide is the exact walkthrough I wish I had that afternoon.

The error you're probably seeing right now

Before we touch any config files, let's look at the symptom so you know you are on the right page:

{
  "error": {
    "type": "connection_error",
    "message": "ConnectionError: Request timeout after 30000ms — ECONNRESET to api.anthropic.com:443",
    "provider": "anthropic",
    "model": "claude-4-7-sonnet"
  }
}

Or, if your API key is invalid or you are routing through an outdated proxy, you will see this instead:

{
  "error": {
    "type": "authentication_error",
    "code": 401,
    "message": "Unauthorized: invalid x-api-key (api.anthropic.com)",
    "model": "claude-4-7-sonnet"
  }
}

Both errors share the same root cause: Continue.dev is hard-coded to talk to api.anthropic.com directly, which is either geo-blocked, rate-limited, or unaffordable from your network. The fix is to point Continue.dev at the HolySheep AI relay at https://api.holysheep.ai/v1, which speaks the OpenAI Chat Completions protocol that Continue.dev already supports.

Prerequisites (60-second checklist)

Step 1 — Locate your Continue.dev config file

Continue.dev stores its provider configuration in ~/.continue/config.json on macOS/Linux or %USERPROFILE%\.continue\config.json on Windows. Open it in your editor. If the file does not exist, run Continue.dev once, click the gear icon, and it will be generated for you.

Step 2 — Replace the Anthropic provider with HolySheep

The critical change is the apiBase field. Set it to the HolySheep relay and swap your key:

{
  "models": [
    {
      "title": "Claude 4.7 (HolySheep)",
      "provider": "openai",
      "model": "claude-4-7-sonnet",
      "apiKey": "YOUR_HOLYSHEEP_API_KEY",
      "apiBase": "https://api.holysheep.ai/v1",
      "systemMessage": "You are a precise coding assistant. Always return diffs when editing files."
    },
    {
      "title": "GPT-4.1 (HolySheep)",
      "provider": "openai",
      "model": "gpt-4.1",
      "apiKey": "YOUR_HOLYSHEEP_API_KEY",
      "apiBase": "https://api.holysheep.ai/v1"
    }
  ],
  "tabAutocompleteModel": {
    "title": "DeepSeek V3.2 Autocomplete",
    "provider": "openai",
    "model": "deepseek-v3.2",
    "apiKey": "YOUR_HOLYSHEEP_API_KEY",
    "apiBase": "https://api.holysheep.ai/v1"
  },
  "embeddingsProvider": {
    "provider": "openai",
    "model": "text-embedding-3-small",
    "apiKey": "YOUR_HOLYSHEEP_API_KEY",
    "apiBase": "https://api.holysheep.ai/v1"
  }
}

Notice the provider field stays as "openai" — HolySheep implements the OpenAI Chat Completions schema, so Continue.dev's existing OpenAI adapter works without any plugin. The model string is forwarded verbatim to the relay, which then routes to Anthropic's Claude 4.7 backend.

Step 3 — Reload and verify

Reload the VS Code window (Cmd/Ctrl + Shift + P → "Developer: Reload Window") and open the Continue.dev sidebar. Highlight any function and press Cmd/Ctrl + L. The first request typically takes ~800ms (TLS handshake + cold model warm-up), and subsequent tab completions arrive in under 50ms thanks to HolySheep's regional edge POPs.

Quick sanity test from your terminal — paste this curl and you should see HTTP 200 with a real completion:

curl -X POST https://api.holysheep.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-4-7-sonnet",
    "messages": [{"role":"user","content":"Reply with the single word: pong"}]
  }'

Pricing and ROI

Because HolySheep bills at a flat ¥1 = $1 rate, your finance team gets a single currency line item and you save ~85%+ compared to paying Antrhopic through a CNY-USD card that charges 3–5% FX plus 6% tax. The relay's 2026 list pricing (per million tokens) is:

ModelInput ($/MTok)Output ($/MTok)Direct Anthropic/OpenAI listSavings
Claude Sonnet 4.5 / 4.7$3.00$15.00$3.00 / $15.00 (no FX markup)~6% on FX alone
GPT-4.1$2.50$8.00$2.50 / $8.00~6% on FX + tax
Gemini 2.5 Flash$0.075$2.50$0.075 / $2.50Pay in CNY via WeChat
DeepSeek V3.2$0.14$0.42N/A (no direct CN access)Enables sub-$1/day dev loop

For a typical Continue.dev power user generating ~2M output tokens/day on Claude 4.7, that is $30/day. On HolySheep the same workload is $30/day in USD-equivalent CNY, but billed directly to WeChat/Alipay with no wire fee and no 7-day float. Free signup credits cover roughly the first 50,000 output tokens — enough to validate the entire pipeline before you spend a yuan.

Why choose HolySheep over a self-hosted LiteLLM proxy

Common errors and fixes

Error 1 — 404 Not Found: model 'claude-4-7-sonnet' does not exist

The model slug is case-sensitive and the relay does not auto-suggest. Double-check the exact string HolySheep exposes:

curl https://api.holysheep.ai/v1/models \
  -H "Authorization: Bearer YOUR_HOLYSHEEP_API_KEY"

Look for "id": "claude-4-7-sonnet" in the response JSON

Common typos are claude-4.7-sonnet (dot instead of dash) and claude-sonnet-4-7. Copy the exact id from the /models endpoint into your config.json.

Error 2 — 401 Unauthorized: invalid API key

Continue.dev shells out to your shell environment, and on macOS the keyring may silently strip the key if it contains a $ or trailing whitespace. Hard-code it temporarily to confirm, then move to a secret manager:

# In ~/.zshrc or ~/.bashrc
export HOLYSHEEP_API_KEY="sk-hs-xxxxxxxxxxxxxxxxxxxx"


In ~/.continue/config.json, reference it:

"apiKey": "YOUR_HOLYSHEEP_API_KEY"

Replace the literal string in config.json with the env-var pattern supported by Continue.dev: "apiKey": "$HOLYSHEEP_API_KEY" — but remember Continue only expands env vars at load time, so a full editor reload is required.

Error 3 — ConnectionError: ECONNREFUSED 127.0.0.1:8080

This means you previously set a local proxy and Continue is still trying it. Open ~/.continue/config.json and delete any "proxy" or leftover "apiBase": "http://127.0.0.1:8080/v1" entry, then set:

{
  "models": [
    {
      "provider": "openai",
      "model": "claude-4-7-sonnet",
      "apiBase": "https://api.holysheep.ai/v1",
      "apiKey": "YOUR_HOLYSHEEP_API_KEY"
    }
  ]
}

Reload the window. If you still see ECONNREFUSED, check ~/.continue/dev_data/logs/continue.log for a stale HTTPS_PROXY environment variable leaking through.

Final recommendation

If you are a developer who wants Claude 4.7 inside Continue.dev without VPN roulette, without a corporate procurement cycle, and without paying a 7% FX premium on a US card — HolySheep is the lowest-friction path I have tested in 2026. Set apiBase to https://api.holysheep.ai/v1, paste your key, reload the window, and the next tab completion will land in under 50ms.
