Anthropic Compatibility API

GoingMerry supports translating incoming Anthropic SDK message payloads to local API formats. This is designed to support developer tools (like Claude Code and OpenClaw) that call the Anthropic Messages API natively.

  • Base Endpoint: http://localhost:11434/v1
  • Supported Endpoint: POST /v1/messages

Request Mapping​

GoingMerry translates parameters from the Anthropic format:

  • max_tokens is mapped to local token limits.
  • system prompts are set as global system parameters.
  • Chat arrays are converted into standard role-based formats.

curl Example​

curl http://localhost:11434/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: merry" \
  -H "anthropic-version: 2023-06-01" \
  -d '{
