Reconcile stock price data from two sources with Claude AI

AI compares daily stock prices from two data sources, resolves conflicts, and keeps an auditable record of every decision.

How the work actually flows

A straight line.

The problem it solves

When two data feeds disagree on a closing price or volume, you're stuck manually digging through both sources to figure out which one to trust. Months later, nobody remembers why a particular number was chosen, which makes audits painful.

Who it fits

Finance and data teams who need trustworthy, auditable market data without manual reconciliation.

How it works

  1. On a schedule, the system pulls end-of-day price and volume data from two sources
  2. Claude compares the two data sets and flags any differences
  3. It applies your tiebreaker rules to decide which value to trust
  4. The reconciled data and Claude's reasoning are saved together in the database
What you get

Price data you can trust without double-checking

You get daily stock prices reconciled between two sources automatically, with every decision logged for a clear audit trail.

What you get

A reconciled, auditable price record with the AI's reasoning stored alongside the data.

What you need

An Anthropic API key, an Alpha Vantage API key, and an ArcticDB instance.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
