List the tech stack and technologies a company's website uses

Run job:company.technographics through the looot API: 5 providers, from $0 per call. Inputs, prices, output shape and code for curl, JavaScript and Python.

List the tech stack and technologies a company’s website uses.

Job id company.technographics, in Enrichment (Company data). As of 2026-10-01, 5 providers serve it through 6 tools. Run job:company.technographics and looot picks one of them; with fallback on, a miss moves on to the next. See Jobs.

Inputs

A job run takes shared input names; looot maps them to each provider’s own fields. See Job inputs.

Any other key you send passes through unchanged. Each tool’s own fields are on its page below.

Providers and prices

A call that fails at the provider costs $0. See What’s free.

Output

Each provider answers in its own shape. Shape of the run’s result from builtwith-free1-api-json, checked against 3 real answers:

{ last, first, domain, groups: { dead, live, name, latest, oldest, categories: { dead, live, name, latest, oldest }[] }[] }

Run it

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":"job:company.technographics","input":{"domain":"example.com"},"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: "job:company.technographics",
    input: {
      domain: "example.com",
    },
    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": "job:company.technographics",
        "input": {
            "domain": "example.com",
        },
        "wait": 30,
    },
    timeout=90,
)
run = response.json()
print(run["status"], run.get("result"))

To pin one provider, send its tool id as endpointId instead of job:company.technographics.
