USDC · per call · x402 on Base

What you get

Calculate auditable per-request, daily, and monthly LLM costs from your own current rates and workload assumptions. Separates cached and uncached input, supports large-context price thresholds and input/output multipliers, adds per-call tool fees, and projects request volume over a billing period. Deterministic, provider-neutral, and makes no model calls or purchases.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
