# Precipiq: The AI Consequences Ledger

> Precipiq records every AI agent decision and links it to its dollar outcome on an immutable, hash-chained ledger. Audit, attribute, and defend.

Precipiq is the financial accountability layer for production AI. Every decision your agents make — a discount offered, a refund approved, an email sent — is recorded on an append-only, hash-chained ledger and linked to its downstream dollar consequence: revenue earned, cost incurred, or liability opened. The result is a forensically auditable trail from "the model said X" to "the customer was charged Y."

## How Precipiq works

<Steps>
  <Step title="Log a decision">
    When your AI agent picks an action, the SDK writes a **Decision Record** — inputs, outputs, confidence score, and a human-in-loop flag — to the append-only ledger.
  </Step>

  <Step title="Chain the record">
    Each record hashes its predecessor's hash into its own `prev_hash` field, creating a tamper-evident chain. A single `verify_chain` call detects any alteration instantly.
  </Step>

  <Step title="Ingest financial events">
    Stripe and QuickBooks webhooks automatically create **Financial Events** when payments clear, refunds fire, or disputes open. You can also POST events directly from your own billing system.
  </Step>

  <Step title="Link and measure">
    The attribution engine connects decisions to events. Your **AI P\&L** dashboard shows live revenue, cost, and open liability attributed per agent — and threshold alerts fire when exposure spikes.
  </Step>
</Steps>
