# Introduction

> Court docket monitoring for AI agents across 2,150 US and Canadian courts. Pay per query. $0.99 USDC via x402. No accounts.

DocketLayer is a pay-per-query API that gives AI agents programmatic access to court docket monitoring across 2,150 courts — all 50 US state court systems, all US federal courts, and Canadian federal and provincial courts.

Your agent submits a case ID and court code, pays **\$0.99 in USDC** via the x402 protocol, and receives structured JSON with change detection built in. No accounts. No subscriptions. No API keys. The payment is the authentication.

## How it works

<Steps>
  <Step title="Submit">
    Your agent makes a GET request to `/v2/case` with a case ID, court code, and optional `last_checked` timestamp.
  </Step>

  <Step title="Pay">
    DocketLayer responds with HTTP 402. Your x402 client pays \$0.99 in USDC on Solana automatically and retries the request.
  </Step>

  <Step title="Receive">
    DocketLayer returns structured JSON — full case context and, if `last_checked` was supplied, a `delta` block showing every new filing since your last check.
  </Step>
</Steps>

## What you need

* A Solana wallet funded with USDC
* The x402 client library configured for your agent
* A case identifier and court code for a covered court (US state, federal, or Canadian)
