External Spend Limit Enforcement for Autonomous Property Agents

Description and use

Autonomous agents in property‑management systems risk overspending when they control their own counters. The solution is to externalize the spend limit to a service like Infrai, where keys and caps are centrally managed, and the agent only makes authenticated calls after estimating cost.

Problem

Autonomous agents risk exceeding spend limits when they control the budget counter, leading to runaway costs and abrupt stops.

Outcome

Agents can safely process high‑volume property‑management tasks without exceeding spend limits, thanks to an external, auditable account cap and pre‑call cost estimation.

Workflow

• 1. Load Infrai public discovery manifest (no key required).
• 2. Apply local admission decision based on the manifest and policy.
• 3. Estimate cost of the intended API call using the live schema.
• 4. If estimate fits within remaining budget, make authenticated spending call with INFRAI_API_KEY.
• 5. If estimate exceeds budget or call fails, abort or retry within external limit constraints.

Evidence

The component that spends must enforce a ceiling the spender cannot edit.

Source

Infrai provides one REST API for your entire backend, with no SDK to install.

Source

A pre‑call estimate is not the hard control. It is the steering signal that lets the loop preserve valuable work.
