Overview

GET /v1/monitor returns a simple boolean — has anything changed since last_checked. It is designed for agents running high-frequency monitoring loops who want minimal data transfer. Use /v1/monitor to check for changes, then call /v1/case only when changed is true to retrieve the full filing details. Base URL: https://api.docketlayer.com Price: $0.99 USDC per successful query

Usage pattern

import time

def monitoring_loop(case_id, court_code, last_checked):
    while True:
        result = client.get(
            "https://api.docketlayer.com/v1/monitor",
            json={"case_id": case_id, "court_code": court_code, "last_checked": last_checked}
        ).json()

        if result["changed"]:
            # Retrieve full filing details
            details = client.get(
                "https://api.docketlayer.com/v1/case",
                json={"case_id": case_id, "court_code": court_code, "last_checked": last_checked}
            ).json()
            handle_new_filings(details["new_filings"])

        last_checked = result["queried_at"]
        time.sleep(3600)  # Check every hour
Both /v1/monitor and /v1/case cost $0.99 per query. The efficiency gain of /v1/monitor is in response payload size, not price. For most monitoring workflows, calling /v1/case directly is simpler and equally cost-effective.
