BuiltWith tool builtwith-lists12-api-json on looot: input fields, $0.0495 per call, output shape, and code to run it with curl, JavaScript or Python.

Paid. Returns websites that use a given technology, with optional filters (country, spend, revenue, employees, other technologies). Validate a technology name for free first with the Trends API.

Tool id: builtwith-lists12-api-json
Provider: BuiltWith
Job: Api json lists12 (lists12.api-json)
Price: $0.0495 per call. A call that fails at the provider costs $0.

Inputs

Name	Type	Required
`COUNTRY`	string	no
`META`	boolean	no
`OFFSET`	string	no
`OTHERTECHS`	string	no
`SINCE`	string	no
`TECH`	string	yes

Output

Shape of the run’s result, checked against 1 real answer:

{ Results: { A, D, E, F, M, Q, R, S, U, FD, FI, LD, LI, LOS: string[], SKU, Country }[], NextOffset }

Every call needs your API token in LOOOT_TOKEN; Sign in shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With wait: 30 the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll GET /v1/runs/<runId>.

Example input with placeholder values:

curl -X POST "https://api.looot.ai/v1/runs" \
  -H "Authorization: Bearer $LOOOT_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"endpointId":"builtwith-lists12-api-json","input":{"TECH":"<TECH>"},"wait":30}'

const response = await fetch("https://api.looot.ai/v1/runs", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LOOOT_TOKEN}`,
    "Content-Type": "application/json",
    "Idempotency-Key": crypto.randomUUID(),
  },
  body: JSON.stringify({
    endpointId: "builtwith-lists12-api-json",
    input: {
      TECH: "<TECH>",
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);

import os
import uuid

import requests

response = requests.post(
    "https://api.looot.ai/v1/runs",
    headers={
        "Authorization": f"Bearer {os.environ['LOOOT_TOKEN']}",
        "Idempotency-Key": str(uuid.uuid4()),
    },
    json={
        "endpointId": "builtwith-lists12-api-json",
        "input": {
            "TECH": "<TECH>",
        },
        "wait": 30,
    },
    timeout=90,
)
run = response.json()
print(run["status"], run.get("result"))

To let looot pick among every provider of this job instead, send job:lists12.api-json as endpointId; see the job page.
