The Token Pricebook™ API provides standardized, model-level token pricing data for major large language model (LLM) providers and vendors. This API exposes input (prompt) and output (completion) token prices, with all values normalized to USD per 1 million tokens, enabling consistent cost comparison across providers and models. In addition to pricing, the dataset includes model performance benchmarks, covering total parameters, active parameters, and context length, allowing users to evaluate cost in relation to model scale and capability.

​
Key Features

  • Access up-to-date token pricing for leading LLM developers and models
  • Retrieve separate input and output token costs
  • Compare models using standardized performance metadata
