Amazon Nova Micro

amazonamazon/nova-micro

How TheRouter serves this differently from the vendor

As the vendor operates it

AWS serves Nova Micro through Bedrock bedrock-runtime with Converse, Invoke, response streaming, guardrails, client-side tool calling, and prompt caching. The native Bedrock card marks structured outputs unsupported and lists text as the only input and output modality.

On TheRouter

TheRouter exposes the same text-only model as OpenAI-compatible /v1/chat/completions under amazon/nova-micro and currently routes it through the US geo Bedrock profile. TheRouter does not make Bedrock structured outputs or non-text modalities available for this model.

API guide

Chat completion

Call Nova Micro through TheRouter's OpenAI-compatible chat surface for low-cost text tasks.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [{"role": "user", "content": "Classify this support ticket as billing, technical, or sales."}]
  }'

Streaming

Bedrock supports response streaming for Nova Micro; use it for chat UIs and long summaries.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "stream": true,
    "messages": [{"role": "user", "content": "Summarize this incident report in five bullets."}]
  }'

Client-side tool calling

AWS marks client-side tool calling as supported. Use it for lightweight dispatch after Nova Micro classifies or extracts the required arguments.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [{"role": "user", "content": "Route this ticket: I cannot update my card."}],
    "tools": [{
      "type": "function",
      "function": {
        "name": "route_ticket",
        "parameters": {"type": "object", "properties": {"queue": {"type": "string"}}}
      }
    }]
  }'

Prompt-constrained JSON

Nova Micro does not support Bedrock native structured outputs. Ask for JSON explicitly and validate downstream.

cURL
curl https://api.therouter.ai/v1/chat/completions \
  -H "Authorization: Bearer $THEROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amazon/nova-micro",
    "messages": [
      {"role": "system", "content": "Return only JSON with keys intent and urgency."},
      {"role": "user", "content": "Need this invoice fixed today."}
    ]
  }'
