​
Overview

Verlon tracks the cost of every request in real-time, giving you visibility into how much you’re spending across all your gates. You can set spending limits at both the account level and per-gate level.

​
Account-Level Spending

​
Viewing Your Spending

Go to Dashboard → Spending to see:
  • Current spending — Total cost in the current billing period
  • Spending limit — Your configured cap (if set)
  • Percentage used — How close you are to your limit
  • Period start — When the current 30-day rolling period began

​
Setting a Spending Limit

  1. Go to Dashboard → Spending
  2. Set your monthly spending limit (in USD)
  3. Choose an enforcement type:
    • Alert only — You’re warned when you exceed the limit, but requests continue
    • Block — Requests are rejected once the limit is hit

​
Alert Threshold

By default, Verlon alerts you when spending reaches 80% of your limit. This gives you time to react before hitting the cap.

​
Gate-Level Spending

Each gate can have its own independent spending limit, separate from your account limit.

​
Configuration

When creating or editing a gate:
  1. Go to the Spending Limits tab
  2. Set a limit amount (USD)
  3. Choose a period: monthly or daily
  4. Choose enforcement: alert_only or block

​
How It Works

  • Each request through a gate increments that gate’s spending counter
  • When the counter exceeds the limit:
    • Alert only: Request proceeds, but the gate’s status shows a warning
    • Block: Request is rejected. The gate’s status changes to suspended until the period resets.
  • Counters reset automatically at the start of each period

​
Cost Calculation

Verlon calculates costs based on:
  • Token count (input + output tokens)
  • Published model pricing from each provider
  • Request type (chat, image generation, etc.)
Cost is tracked per request and aggregated into gate-level and account-level totals.
If you’re using BYOK (Bring Your Own Keys), Verlon still tracks estimated costs for analytics and limit enforcement. Your actual provider bill may vary slightly from Verlon’s estimates.

​
Cost Alerts (Agent Gates)

Agent gates support alert-only cost thresholds — per-trace and per-session-cumulative — that notify you without ever interrupting a run. See Agent Gates for details.

​
Spending API

You can programmatically check and manage spending via the API: 
# Get current spending
curl https://api.verlon.ai/v1/spending \
  -H "Authorization: Bearer sk-vrln-your_key"
