# TokenLine

> The financial control layer for autonomous agents. TokenLine is the live spend meter and signed ledger for every AI agent you run — it names every token, caps every agent, and proves every dollar, in the request path, before the invoice ever arrives.

TokenLine (formerly TRACE) sits between your application and your model providers. Unlike cost dashboards that report spend after the fact, TokenLine enforces budgets at request time and issues a cryptographically signed record for every dollar spent — attributing it to the exact agent, sub-agent, task, customer, and outcome responsible.

## The problem it solves
- Autonomous agents spend money without human approval: they spawn sub-agents, retry, and reason in loops.
- Cost now emerges from agent behavior, not from provisioned traffic — so traditional FinOps tooling misses it.
- Provider invoices arrive weeks late; by then the spend is gone and the agent that caused it is still running.
- A single retry loop overnight can burn a month's budget with no one awake to catch it.

## What TokenLine does
- Cap: per-agent, per-task, per-day hard budgets enforced in the request path, before a call becomes billable. Circuit breakers halt runaway loops automatically (HTTP 402).
- Name: real-time attribution of every token to the specific agent, sub-agent, task, customer, and outcome — not reconstructed from a provider bill.
- Prove: a cryptographically signed ledger of every dollar — which agent, on whose authority, for what result. Court-grade, audit-grade, board-grade.

## Who it is for
- Technical founders and engineering leads shipping autonomous agents into production.
- Platform engineering and DevOps teams now made accountable for AI spend and ROI.
- Teams running multiple model providers (OpenAI, Anthropic, and others) that need spend control across agents, members, and departments.

## How it is different
- Incumbents (gateways and FinOps dashboards) now all claim real-time enforcement. TokenLine's differentiators are: (1) a cryptographically signed, per-agent, defensible receipt for every dollar, and (2) founder-legible, Stripe-grade UX with a two-line install — built for the person whose credit card the agent is holding, not only the finance org.

## Pricing
- Starter — $19/mo: two-line install, full visibility and live per-agent attribution, one workload.
- Plus — $299/mo: real-time caps, circuit breakers, multi-provider, per-agent budgets, anomaly alerts, team seats.
- Pro — $999/mo: signed ledger, outcome attribution, SSO/SOC2, chargeback/showback, the defensible receipt.
- Founding 1,000: the first 1,000 who connect a real workload lock Pro features at the Plus price for life, and get the Overspend Guarantee — if TokenLine doesn't catch more waste than it costs in the first 30 days, it's free and the gap is refunded up to one month's price.

## Positioning, in one line
- The line between your agents and your money. Your agents don't sleep. They spend. TokenLine is the live meter — and the signed ledger — that holds the line.
