Price a call with the free API

No key, no account. It uses this same table, and with "usage_shape": "openai" it takes the cached tokens out of prompt_tokens first, so they aren't billed twice.

curl -s https://api.aight.studio/api/cost \
  -H 'content-type: application/json' \
  -d '{"model": "deepseek-chat", "input_tokens": 20000, "output_tokens": 1500, "cache_read_tokens": 12000}'

Returns cost_usd, a breakdown per token type, the rates per 1M, and when the table last changed. Rates only: GET https://api.aight.studio/api/pricing?models=a,b. Rate-limited per client; an unknown model is a 404, never $0. Full API docs.
