TensorFeed Inference Cost Projection
https://tensorfeed.ai/api/premium/cost/projectionOverview
Project the cost of a token-usage workload across 1-10 AI models. Returns daily, weekly, monthly, and yearly totals per model plus a ranking by cheapest monthly. The canonical "given my workload, what would each model cost me" call. AFTA fair-trade: Ed25519-signed receipt on every paid call, automatic no-charge on 5xx, schema failure, or stale data.
