mirrored listing x402 eip155:8453

Current LLM API pricing, verified by hand every week: input and output USD per million tok

Current LLM API pricing, verified by hand every week: input and output USD per million tokens, cached-input rates where published, and context windows across Anthropic, OpenAI, Google, xAI and Together. Every row is read off the provider's own page on its stated date and carries that URL. A row the provider stops publishing is dropped rather than carried forward, and a context window we could not verify is null rather than guessed. Includes a changes block naming every price that moved.
