Sandbox mode lets you test your integration against real API endpoints using fixture data — correct response structure, no x402 payment required, no USDC spent.

​
Enabling sandbox mode

Add ?test=1 to any request URL, or send the X-DocketLayer-Test: 1 header. 
# Query string
curl "https://api.docketlayer.ai/v2/case?test=1&case_id=1:24-cv-01234&court_code=nysd"

# Header
curl -H "X-DocketLayer-Test: 1" "https://api.docketlayer.ai/v2/case?case_id=1:24-cv-01234&court_code=nysd"

​
Sandbox behavior

  • No x402 payment is required or processed
  • meta.query_cost_usd is always 0
  • meta.sandbox is always true
  • Response data is a fixture — the case name, parties, and filings are synthetic
  • delta.changed is always false (no new filings in sandbox)
  • All parameter validation runs normally — invalid parameters still return errors

​
Fixture response

All endpoints return fixture data reflecting the response structure. For GET /v2/case: 
{
  "meta": {
    "request_id": "req_01sandbox",
    "queried_at": "2026-04-29T12:00:00Z",
    "query_cost_usd": 0,
    "coverage_status": "full",
    "cache_age_seconds": 120,
    "context_delivered": "basic",
    "language_delivered": "en",
    "truncated": false,
    "sandbox": true,
    "tag": null
  },
  "case_id": "1:24-cv-01234",
  "court_code": "nysd",
  "case": {
    "case_number": "1:24-cv-01234",
    "case_name": "Smith v. Jones [Sandbox]",
    "case_type": "civil",
    "court_code": "nysd",
    "court_name": "Sandbox Court",
    "jurisdiction_country": "US",
    "status": "open",
    "assigned_judge": "Hon. Sandbox Judge",
    "primary_parties": [
      { "name": "John Smith", "type": "plaintiff" },
      { "name": "Acme Corp.", "type": "defendant" }
    ],
    "appellate": null
  }
}

​
Testing with code

import requests

# Test your parsing logic without spending USDC
response = requests.get(
    "https://api.docketlayer.ai/v2/case",
    params={
        "test": "1",
        "case_id": "1:24-cv-01234",
        "court_code": "nysd",
        "last_checked": "2026-01-01T00:00:00Z"
    }
)

data = response.json()
assert data["meta"]["sandbox"] is True
assert data["meta"]["query_cost_usd"] == 0

const url = new URL("https://api.docketlayer.ai/v2/case");
url.searchParams.set("test", "1");
url.searchParams.set("case_id", "1:24-cv-01234");
url.searchParams.set("court_code", "nysd");

const data = await fetch(url).then(r => r.json());
console.assert(data.meta.sandbox === true);

​
Batch sandbox

POST /v2/cases/batch also supports sandbox mode. All queries in the batch return fixture data regardless of the case IDs or court codes provided. 
curl -X POST "https://api.docketlayer.ai/v2/cases/batch?test=1" \
  -H "Content-Type: application/json" \
  -d '{"queries":[{"case_id":"1:24-cv-01234","court_code":"nysd"}]}'

​
Notes

  • Sandbox and live modes share the same endpoint URLs — only the test=1 parameter or X-DocketLayer-Test header differentiates them
  • Sandbox requests are not logged against your wallet’s rate limit
  • The free /v2/status endpoint does not support sandbox mode — it always returns live data
