Claude Code

Route Claude Code at LLMRPM's Anthropic-compatible endpoint.

Configuration

Setting	Value
API shape	Anthropic-compatible
Base URL	`https://llmrpm.com/api`
Auth	`Authorization: Bearer llmrpm_...`

Set ANTHROPIC_AUTH_TOKEN to your LLMRPM API key so the client sends a bearer token.
Set ANTHROPIC_BASE_URL to https://llmrpm.com/api — the client appends /v1/messages.
Set default model IDs with ANTHROPIC_DEFAULT_SONNET_MODEL and ANTHROPIC_DEFAULT_HAIKU_MODEL.
Increase API_TIMEOUT_MS for long, tool-heavy sessions.

Example

settings.json

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "llmrpm_YOUR_KEY",
    "ANTHROPIC_BASE_URL": "https://llmrpm.com/api",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-5",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4.5",
    "API_TIMEOUT_MS": "3000000"
  }
}

Recommended models

Any public ID from the model list works. Common picks:

claude-sonnet-5— strong model for reasoning, refactors, and coding agents.
claude-haiku-4.5— fast option for autocomplete, small questions, and lightweight tasks.
deepseek-v4-pro— alternative based on your active catalog and plan.

Troubleshooting

Symptom	Cause & fix
Authentication error	Check that the API key has no extra spaces and has not been revoked in the dashboard.
Model rejected	Use a public model ID returned by GET /api/v1/models; do not use display names or aliases.
Connection issue	Confirm the configured base URL is exactly the one shown above and that your network allows HTTPS to llmrpm.com.

Notes

Claude Code calls /v1/messages, not /v1/chat/completions.
LLMRPM authenticates with a bearer token, so use ANTHROPIC_AUTH_TOKEN rather than an x-api-key value.
If authentication fails, confirm the key has not been revoked in the dashboard.
