IČO API: JavaScript, Python a PHP

Priame HTTP príklady bez vlastného SDK. JavaScript používa vstavaný fetch, Python knižnicu requests a PHP rozšírenie cURL. Príklady obsahujú ošetrenie chýb.

JavaScript / TypeScript — vyhľadávanie

async function searchCompanies(query: string, country = "sk") {
  const params = new URLSearchParams({ q: query, country, limit: "10" });
  const res = await fetch(`https://api.subjekt.sk/v1/search?${params}`);

  if (!res.ok) {
    const err = await res.json();
    throw new Error(`API chyba ${res.status}: ${err.code} — ${err.message}`);
  }

  const data = await res.json();
  return data.results;
}

// Použitie
try {
  const firmy = await searchCompanies("slovnaft");
  console.log(firmy);
} catch (e) {
  console.error("Vyhľadávanie zlyhalo:", e);
}

JavaScript / TypeScript — detail entity

async function getEntity(ico: string, country = "sk") {
  const res = await fetch(
    `https://api.subjekt.sk/v1/entity/${ico}?country=${country}`
  );

  if (res.status === 404) {
    return null; // firma nenájdená
  }

  if (!res.ok) {
    const err = await res.json();
    throw new Error(`API chyba ${res.status}: ${err.code} — ${err.message}`);
  }

  return res.json();
}

// Použitie
const entity = await getEntity("31322832");
if (entity) {
  console.log(`${entity.name}, IČO: ${entity.ico}`);
} else {
  console.log("Firma nenájdená");
}

Python — vyhľadávanie

import requests

def search_companies(query: str, country: str = "sk") -> list:
    r = requests.get(
        "https://api.subjekt.sk/v1/search",
        params={"q": query, "country": country, "limit": 10},
        timeout=8
    )
    r.raise_for_status()  # vyhodí HTTPError pri 4xx/5xx
    return r.json()["results"]

# Použitie
try:
    firmy = search_companies("slovnaft")
    for firma in firmy:
        print(f"{firma['name']} ({firma['ico']})")
except requests.HTTPError as e:
    print(f"API chyba: {e.response.status_code}")
except requests.RequestException as e:
    print(f"Sieťová chyba: {e}")

Python — detail entity

import requests

def get_entity(ico: str, country: str = "sk") -> dict | None:
    r = requests.get(
        f"https://api.subjekt.sk/v1/entity/{ico}",
        params={"country": country},
        timeout=8
    )
    if r.status_code == 404:
        return None  # firma nenájdená
    r.raise_for_status()
    return r.json()

# Použitie
try:
    entity = get_entity("31322832")
    if entity:
        print(f"{entity['name']}, DIČ: {entity.get('dic')}")
    else:
        print("Firma nenájdená")
except requests.HTTPError as e:
    print(f"API chyba: {e.response.status_code}")

PHP — vyhľadávanie

    if (json_last_error() !== JSON_ERROR_NONE) {
        throw new RuntimeException("Neplatná JSON odpoveď");
    }

    if (isset($data["code"])) {
        throw new RuntimeException("API chyba: " . $data["code"] . " — " . $data["message"]);
    }

    return $data["results"] ?? [];
}

// Použitie
try {
    $firmy = searchCompanies("slovnaft");
    foreach ($firmy as $firma) {
        echo $firma["name"] . " (" . $firma["ico"] . ")\n";
    }
} catch (RuntimeException $e) {
    echo "Chyba: " . $e->getMessage() . "\n";
}

PHP — detail entity

        throw new RuntimeException("API chyba: " . $data["code"] . " — " . $data["message"]);

// Použitie
