LLM API cost calculator
Estimate monthly API spend from daily request volume, tokens per request, and prompt-cache hit rate.
A first-party, USD, text-generation API estimate using each provider's standard input, cached-input, and output token rates. It excludes prompt-cache writes, tool/function-calling tokens, retries, hosting, and volume or enterprise pricing tiers not reflected in the public rate card. It is not a full projected bill.
