API reference

Tool calling

Let a supported model request actions your application controls.

OPENAI BASE URLhttps://www.modelmesh.in/api/v1

Choose a capable model

Check the published tools capability. The gateway accepts tools and tool_choice; support depends on the upstream model. Not every catalog model can run a coding agent.

Your application executes tools

Supply a function name, description, and JSON input schema. Validate returned tool_calls arguments, execute authorized actions in your application, and return a tool message with the matching tool_call_id.

Keep the loop bounded

Set timeouts, output limits, and a maximum number of tool iterations. Treat generated arguments as untrusted input. ModelMesh routes model requests; it does not execute your functions or grant access to your files.
