# Overview

The Spend Graph, the products it ships, and how to reach the data.

American Spend builds the data layer of American commerce. The economy produces roughly 120 million transactions a day. We structure that signal into the Spend Graph and ship it as institutional datasets through Revere, and as programmatic access through MCP and the API.

### Start here

* [The Spend Graph](/the-spend-graph.md) is the record.
* [Methodology](/methodology.md) is how the numbers are made.
* [Measures](/measures.md) are the four figures every answer carries.
* [Products](/products.md) are Revere, the API, MCP, and Oracle.
* [Pricing](/pricing.md) is what a call costs.
* [MCP Methods](/mcp-methods.md) are the calls that agent can make.
* [Data practices](/data-practices.md) and [Support](/support.md) are how we handle the data and how to reach us.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.americanspend.com/overview.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
