Point Claude Code at aphiii.

aphiii speaks the Anthropic Messages API, so Claude Code works out of the box — better cache hit rates than most clients, at a fraction of the official price. An OpenAI-compatible endpoint is also available.

1 · configure claude code

recommended

// ~/.claude/settings.json
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://ap.hiii.boo",
    "ANTHROPIC_AUTH_TOKEN": "sk-ant-api03-xxx"
  }
}

Drop this into ~/.claude/settings.json. Your sk-ant-api03- key authenticates over Claude Code's native API-key header or Authorization: Bearer. That's it — run claude and traffic routes through aphiii.

2 · pick your models

// Use the real Claude model names you want (optional)
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://ap.hiii.boo",
    "ANTHROPIC_AUTH_TOKEN": "sk-ant-api03-xxx",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-8",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4-5"
  }
}

Send the real Claude model name and aphiii passes it straight through to the pool — no aliases to learn. Or set defaults per slot above. Switch live with /model.

Starter

Sonnet 4.6 and Haiku 4.5

Best value for daily coding, agents, and batch work.

Pro

All models + Opus 4.7 and 4.8

For reasoning-heavy and long-context work, with the highest cache hit rates.

OpenAI-compatible endpoint

Any OpenAI SDK works — point it at /v1/chat/completions with your key and a Claude model name in the model field.

curl https://ap.hiii.boo/v1/chat/completions \
  -H "Authorization: Bearer sk-ant-api03-xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-4-6",
    "messages": [{"role":"user","content":"Ship a concise answer."}],
    "stream": true
  }'

retention policy

Prompts and completions are not stored by the application layer. Usage logs keep only timestamp, key id, route, model alias, status, latency, token counts, and cost.
