Quick start

Search for a model by name:

curl "https://api.modelmonitor.dev/models"

{
  "total": 3,
  "data": [
    {
      "id": "anthropic/claude-sonnet-5-5",
      "name": "Claude Sonnet 5.5",
      "provider": "anthropic",
      "context_window": 1000000,
      "pricing": { "input_per_million": 2, "output_per_million": 10 },
      "capabilities": { "tool_calling": true, "reasoning": true, "vision": true },
      "hosted_on": [{ "provider": "Amazon Bedrock", "slug": "amazon-bedrock", "…": "…" }]
    }
  ]
}

Prices are per million tokens in USD. typical_request gives the cost of a 2,000 input and 500 output token call, so models compare at a glance.

Need more?

The free API is rate limited. Paid access removes the limit and adds webhook notifications, so we call your endpoint whenever a model’s pricing or capabilities change. To buy access, email contact@modelmonitor.dev. We’re happy to talk through what you need.
