Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get utility responses for a ticket” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "appsca.undergroundservicealert.org/get_utility_responses",
    "input": {
      "ticket_number": "A263150412-00A",
      "city": "Stockton"
    }
  }'

{
  "status": "completed",
  "data": {
    "ticket_number": "A263150412-00A",
    "responses": [
      {
        "station_code": "ACMEGAS",
        "station_code_name": "Acme Gas Distribution",
        "response_date": "2026-11-11T14:20:00-08:00",
        "response_code": "010",
        "response_description": "Locate area marked",
        "comments": "Marked 4 in. gas main along north curb"
      }
    ],
    "awaiting_response": [
      "GLBXWTR"
    ]
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

USA North 811’s own options

USA North 811 offers OneCallAccess, a free online ticket program for California and Nevada, with mobile apps and a public Positive Response Ticket Search. It does not document an API for excavators. PelicanCorp, which makes OneCallAccess, describes an API for submitting One Call inquiries from your own systems, without a price or a way to request it through USA North 811.

Signing in to USA North 811

OneCallAccess signs you in with a username and password, and each state has its own program and account: one for California, one for Nevada. With Fous you sign in once through OneCallAccess's own sign-in with your own account. The login is sealed with AES-256, code and AI agents never see it, and an expired session is signed back in.

Worth knowing

A ticket is active for 28 calendar days

In both states a ticket lasts 28 calendar days from issuance and can be renewed online by the end of the 28th day. In California the markings must still be clearly visible; in Nevada a ticket can be renewed only two times.

Every operator must respond before you dig

Excavation may begin only after all utility operators have responded and any required on-site meeting is complete. A start date and time that has passed is not enough on its own.

No response: notify again every two hours

Once the legal notice and the ticket's start date and time have passed, you can submit a No Response (NRSP) notification. You can repeat it every two hours.

One ticket per company, half a mile per ticket

Each company breaking ground needs its own ticket. Locations should be no longer than half a mile, so long jobs use Next Job Phase to copy a ticket into the next section.
