By the time you find out it was a miss, you already paid.
Pre-flight check before takeoff. If the payload doesn't fit the plane (context window), you don't board it.
Right now the entire AI industry is boarding every flight blind. No weight check, no gate, no manifest. Just throw the content at the API and hope it fits.
If it doesn't — you already paid for the taxi to the runway and a return flight.
Slash is TSA for tokens. Except it's 4.8 KB, takes less than a millisecond, and actually saves you money instead of wasting your time.
The fastest growing expenditure in human history. Every model gets more expensive at the frontier. Every company adding AI to everything. Every agent making autonomous calls 24/7.
The meter is running and it never stops.
Slash your token cost, optimize your spend; the gate is a file smaller than your favicon.
Wrong estimate? — API returns exact counts anyway
Combined: $49.1K/mo in sunk cost.
bunx slash-tokens| Savings | $1,000 |
| Slash 10% | $100 waived |
| Team | $39 for the data |
| Additional savings | $61 |
You keep the $1,000. 10% is the long-term model — not billed today. Additional savings only shows when it beats $39.
Enterprise — custom. Talk to us.
$39 for the data.
Traditional SaaS: "Here's your bill. It goes up every month. You hate us a little more each quarter."
/slash: "Here's what you saved. The library was free. The dashboard is how finance sees it."
You're not a line item on the cost sheet. You're on the savings sheet.
Copy the red box below. Send it to your dev. That's it.
bunx slash-tokens
Your dev runs it. Sees the number. Ships the fix. One line in your codebase:
import 'slash-tokens/auto'
Sunk cost diverted. Done.
Context is philosophical. Tokens are invoices.
/slash is money. Tokens are the unit of currency in AI. Every single API call is a cash register. /slash sits at the register.
Nobody argues with "we reduced your invoice."
