API reference

Anthropic Messages

Connect Anthropic-style clients to the Messages gateway.

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

Use the correct base URL

The HTTP endpoint is /api/v1/messages. Anthropic SDKs append /v1/messages, so their base URL is the site origin plus /api, without trailing /v1. Use the Anthropic URL in Connections.

Request fields

Provide model, messages, and a positive max_tokens. A system prompt belongs at the top level. Authentication accepts x-api-key or Authorization: Bearer. Choose a published Claude model appropriate for your client.

Compatibility boundaries

The gateway adapts supported requests to the configured provider. Streaming and tools depend on that provider and model. Native token counting, files, and batches are not implemented by this app.
