Pre-Call Estimates Beat Usage Reports for Agent Budgets (With Hard Caps)

说明与用途

预调用成本估算使得在调用模型前做出决策，记录实际使用以进行计费，并通过硬账户上限限制支出，全部使用单一 API 密钥和统一计费。

问题

B2B SaaS products need a way to decide before calling expensive models whether a customer’s remaining allowance permits the operation, while still reconciling actual usage for invoicing and enforcing hard account caps.

结果

The system now prevents overages by rejecting expensive branches preemptively, accurately records actual usage for invoicing, and limits exposure with a hard account cap, all while using a single API key and consolidated billing.

工作流

• 1. Generate a stable operation ID and attach customer ID before external work starts.
• 2. Call the pre-call cost estimate endpoint (e.g., Infrai) with the operation payload.
• 3. If estimate <= remaining allowance, allow the operation; otherwise reject.
• 4. After the operation, record actual usage and attribute it to the same operation ID and customer ID.
• 5. Reconcile estimate vs. actual usage and update customer allowance.
• 6. Enforce a hard account cap that overrides local allowance if exceeded.
• 7. Generate post-call usage reports for invoicing and audit.
• 8. Periodically review estimate error, attribution gaps, and duplicate lines to adjust tolerance.

证据

Use a pre-call cost estimate to decide whether an agent may take an expensive branch, record post-call usage for invoice reconciliation and calibration, and enforce an account cap as the final damage boundary.
