OpenClaw Spending Limits: Budget Cap Playbook

This page focuses on cost safety, not model quality. The goal is to cap worst-case spend while preserving reliable task completion.

1-Minute Cost Safety Baseline

Apply provider cap + runtime token cap together.

Budget Guardrails

# 1) Create provider API key with spending cap in provider console

# 2) Set runtime token ceiling in OpenClaw config
{
  "llm": {
    "maxTokens": 4096
  }
}

# 3) Restart and verify
openclaw gateway restart

Why Spending Limits Need Two Layers

Provider-level cap: hard monthly/daily financial ceiling.

Runtime token cap: reduces per-task runaway behavior.

Both together: prevents both “slow leak” and “single-task spike”.

Step 1: Set Provider Budget Cap

Create a dedicated API key for OpenClaw and enforce spending limits in your provider (or proxy/gateway) console. Avoid sharing unrestricted keys across projects.

Step 2: Add OpenClaw Token Controls

Token Ceiling Example

{
  "llm": {
    "maxTokens": 4096,
    "temperature": 0.7
  }
}

Step 3: Monitor and Tune

Review usage weekly, then tune by workload class. If tasks truncate too often, raise caps in small steps rather than removing guardrails entirely.

Evidence base for provider-specific cap workflows is still limited. Treat this as an operational baseline and validate in your own billing data before scaling.

Generate a Cost-Safe Config

Use Config Wizard to generate a budget-oriented baseline, then add provider-side caps for full cost protection.
