Anthropic protocol

Send native Anthropic Messages requests through Tikway.

Send Anthropic Messages requests to POST https://api.tikway.ai/v1/messages. Put your Tikway API key in x-api-key, add anthropic-version: 2023-06-01, and use Anthropic fields such as model, max_tokens, and messages in the JSON body.

curl https://api.tikway.ai/v1/messages \
  -H "x-api-key: $TIKWAY_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-4-6",
    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Successful responses follow the Anthropic Messages format. For complete request and response fields, open API Reference → Chat completions → Anthropic protocol. Gateway-generated errors use an outer type: "error" field; see Status codes and responses.
