AAnthropic: Claude Haiku 4.5 API
anthropic/claude-haiku-4.5
Claude Haiku 4.5 API is the lowest-priced Anthropic model in this catalog. Its 200K context is smaller than Sonnet and Opus, but text, image, and file input make it a practical front line for lightweight agent work. [1]
Claude Haiku 4.5 API has no current mapped LLM2014 logic row, so its page focuses on verifiable economics and modalities. It costs one third of Claude Sonnet 4.6 at official input and output rates. [1][2]

Providers
APINEED lists Claude Haiku 4.5 API with text, image, and file input, text output, and a 200K context window. APINEED routing and prepaid rates are identified separately. [1]
Discount
The 50% APINEED rate brings Haiku to $0.50 input and $2.50 output per million tokens. Repetitive classification and extraction gain more from that low base than occasional complex reasoning. The table compares official Claude Haiku 4.5 API pricing with the APINEED prepaid rate.

Quick Start
Connect Claude Haiku 4.5 API without changing the OpenAI-style request shape. Route short summaries, triage, classification, and simple multimodal checks to Haiku. Escalate ambiguous cases to Sonnet or Opus rather than forcing one tier to handle every turn.
Get your API key
Create an APINEED key for Claude Haiku 4.5 API and keep it in an environment variable.
export API_NEED_API_KEY=sk-apineed-v1-...Make your first request
Use claude-haiku-4.5 for Claude Haiku 4.5 API with the APINEED API. The request shape is compatible with OpenAI chat completions, so most SDKs only need a base URL change.
