`simplified`	boolean	no

Output

Shape of the run’s result, checked against 3 real answers:

{ meta: { cost, credits }, email: { name, domain, isFree, address, isValid, pattern, fullName: { last, nick, error: unknown[], first, title, middle, suffix }, isDisposable, isSubaddress, isValidFormat }, company: { meta: { score, mysqlId, syncedAt, similarity }, urls: { registrar }, about: { name, industry, nameAlts: string[], languages: string[], nameLegal, industries: string[], yearFounded, businessType, totalEmployees, yearFoundedPlace, totalEmployeesExact }, assets: { cover: { ... }, logoSquare: { ... } }, domain: { tld, state, domain, status, registrar, domainName }, socials: { github: { ... ...

The shape is cut here. Signed in, looot inspect thecompaniesapi-companies-by-email prints all of 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":"thecompaniesapi-companies-by-email","input":{"email":"jane.doe@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: "thecompaniesapi-companies-by-email",
    input: {
      email: "jane.doe@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": "thecompaniesapi-companies-by-email",
        "input": {
            "email": "jane.doe@example.com",
        },
        "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:company.enrich as endpointId; see the job page.
