Chile — Taxpayer (RUT) lookup

Use this endpoint when you need taxpayer-oriented identity data for a Chilean RUT (not the civil-registry cedula flow). It complements Identity verification in Chile (v2/cl/cedula), which is tuned to RUN/civil lookup.

API reference

Endpoint

https://api.verifik.co/v2/cl/taxpayer

Returns name fields and identifiers aligned with tax registry usage—ideal for KYB, supplier onboarding, and invoice validation where the RUT must match registered taxpayer data.

Headers

Name	Value
Accept	application/json
Authorization	Bearer <token>

Parameters

Name	Type	Required	Description
documentType	string	Yes	Must be RUT.
documentNumber	string	Yes	Tax identifier (digits; formatting normalized by the service).

Request

Node.js

import axios from "axios";

const { data } = await axios.get("https://api.verifik.co/v2/cl/taxpayer", {
  params: { documentType: "RUT", documentNumber: "263007905" },
  headers: { Accept: "application/json", Authorization: `Bearer ${process.env.VERIFIK_TOKEN}` },
});
console.log(data);

Python

import os, requests

url = "https://api.verifik.co/v2/cl/taxpayer"
headers = {"Accept": "application/json", "Authorization": f"Bearer {os.getenv('VERIFIK_TOKEN')}"}
params = {"documentType": "RUT", "documentNumber": "263007905"}
r = requests.get(url, headers=headers, params=params)
print(r.json())

Notes

• Prefer v2/cl/cedula for civil-registry RUN identity matching; use v2/cl/taxpayer when the RUT taxpayer record is the source of truth.
