Every AI API price change, on the record.

Stop hardcoding a table that rots.

Every app that touches an LLM ends up with a pasted map of model ids to prices and context windows, and it is wrong within a month. Fetch the live one instead — open data, no key, MIT licensed.

Works with any coding agent over MCP, so it quotes today's prices instead of guessing from training data.
