Claude Haiku 5.5 API
Claude Haiku 5.5 is a language model from anthropic, available on Routeriva under the model ID claude-haiku-5-5. You call it with the same sk- key you use for every other model — no separate anthropic account is needed.
On Routeriva it costs $0.04 per 1M input tokens and $0.20 per 1M output tokens, compared with the official list price of $0.10 / $0.50 — about 60% less. Prices shown are the lowest across the routes that serve this model; your key is charged at its own route's price.
Because Routeriva speaks the native Anthropic /v1/messages format, Claude Haiku 5.5 works directly in Claude Code, Cline and the Anthropic SDK, with extended thinking and prompt caching passed through unchanged. It also works through the OpenAI-compatible /v1/chat/completions endpoint.
