# Quickstart

> Create a key, resolve an address and read cited property data.

<Steps>
  <Step title="Create an API key">
    Sign in to the [developer portal](https://portal.quoindata.com) and create a key under **API keys**. New accounts include welcome credit, so you can make data calls before adding a payment method.

    ```bash theme={null}
    export QUOIN_KEY="qk_..."
    ```
  </Step>

  <Step title="Find the property (free)">
    Resolve a street address to a q\_id. Text after the first comma is ignored.

    ```bash theme={null}
    curl -G "https://portal.quoindata.com/api/v4/find" \
      -H "Authorization: Bearer $QUOIN_KEY" \
      --data-urlencode "q=1350 Pennsylvania Ave NW" \
      --data-urlencode "jurisdiction=11"
    ```

    ```json theme={null}
    {
      "status": "ok",
      "data": {
        "items": [
          {
            "q_id": "addr_01a12e0d-2ece-77ad-b5b0-430ab9658f29",
            "type": "addr",
            "label": "1350 PENNSYLVANIA AVE NW",
            "jurisdiction": "11001",
            "matched_on": "address"
          }
        ]
      }
    }
    ```
  </Step>

  <Step title="See what is linked (free)">
    ```bash theme={null}
    curl "https://portal.quoindata.com/api/v4/entities/addr_01a12e0d-2ece-77ad-b5b0-430ab9658f29/connected" \
      -H "Authorization: Bearer $QUOIN_KEY"
    ```

    The address links to a parcel (`at`), and the parcel to its tax account (`billed_to`).
  </Step>

  <Step title="Read a property summary (billable)">
    ```bash theme={null}
    curl "https://portal.quoindata.com/api/v4/entities/parc_5df9c647-c1fe-6e85-1690-a0710b870cfb/summary" \
      -H "Authorization: Bearer $QUOIN_KEY" \
      -H "Idempotency-Key: $(uuidgen)"
    ```

    ```json theme={null}
    {
      "status": "ok",
      "data": {
        "q_id": "parc_5df9c647-c1fe-6e85-1690-a0710b870cfb",
        "items": [
          {
            "field": "year_built",
            "label": "Year built",
            "value": "1949",
            "citation": {
              "source": "Fairfax County Department of Tax Administration",
              "dataset": "Tax Administration's Real Estate - Dwelling Data",
              "as_of": "2026-10-12"
            },
            "record_ref": "rec_6a19a8b5-7071-6911-26d9-1840798daae9",
            "alternatives": []
          }
        ]
      }
    }
    ```
