Haiku API
OpenAI-compatible API proxy for Claude Haiku 4.5 via chatgpt.org.
Supports tool/function calling, auto-continue for the 1K token limit, rotating proxy, and SSE keep-alive.
Features
- Tool/Function Calling: Full OpenAI-compatible tool calling support. Converts
toolsdefinitions to system prompts, parses Claude's output for<tool_call_>blocks, and returns properly formattedtool_callsresponses. - Auto-Continue: When the upstream 1K token limit is hit, automatically continues the response with "Continue" messages.
- SSE Keep-Alive: Sends keep-alive comments during continuation gaps to prevent socket timeouts.
- Rotating Proxy: Supports unstable rotating proxies with automatic retries on connection failures.
- Message Normalization: Handles Orchids.app's content array format and converts it to plain text.
