Cursor Integration - ModRouter

Endpoint

https://api.modrouter.online/cursor

Cursor sends hybrid payloads for agent flows: the request reaches chat-completions-style paths but can contain OpenAI Responses-style input and Anthropic-style tool blocks. ModRouter’s /cursor integration parses that shape, routes it through the Responses pipeline, and converts responses back into chat-completions-compatible output.

Supported Route Groups

Route family	ModRouter prefix
Cursor chat completions	`/cursor/v1/chat/completions`, `/cursor/chat/completions`
Model listing	`/cursor/v1/models`, `/cursor/models`
Anthropic-compatible routes	`/cursor/v1/messages`, `/cursor/v1/messages/count_tokens`, and related Anthropic paths

Cohere-compatible routes	`/cursor/v2/chat`, `/cursor/v2/embed`, `/cursor/v2/rerank`, `/cursor/v1/tokenize`

When to Use It

Use /cursor for Cursor’s OpenAI-compatible base URL override. Do not use /openai for Cursor unless you intentionally want to bypass Cursor-specific request normalization. For step-by-step product setup, see Cursor.
