Utilizzo dei Parser

I parser sono un modo per trasformare dati non strutturati in dati strutturati compatibili con il tuo backend. Combinando i parser con l’API di Olostep (crawls, scrapes, batches) è possibile trasformare qualsiasi sito web in una chiamata API per restituire il JSON di cui hai bisogno. I parser sono ideali quando hai bisogno di dati su larga scala in modo ricorrente dagli stessi siti web. Questo approccio è significativamente più economico e veloce rispetto all’estrazione LLM e restituisce solo il JSON richiesto. Offriamo parser pre-costruiti per siti web e casi d’uso popolari. Puoi anche creare i tuoi parser in pochi minuti con gli LLM utilizzando la dashboard o chiedere al nostro team di farlo per te.

Parser Pre-Costruiti

Offriamo diversi parser pre-costruiti per siti web popolari:

Google Search: @olostep/google-search
Amazon Product: @olostep/amazon-it-product
Estrazione Email: @olostep/extract-emails

Esempio di Utilizzo

import requests
import json

endpoint = "https://api.olostep.com/v1/scrapes"
payload = {
    "formats": ["json"],
    "parser": {"id": "@olostep/google-search"},
    "url_to_scrape": "https://www.google.com/search?q=alexander+the+great&gl=us&hl=en",
    "wait_before_scraping": 0,
}
headers = {
    "Authorization": "Bearer <YOUR-API-KEY>",
    "Content-Type": "application/json"
}

response = requests.request("POST", endpoint, json=payload, headers=headers)
print(json.dumps(response.json(), indent=4))

Formato della Risposta

Quando fai una richiesta all’API di Olostep con il formato del parser, riceverai una risposta JSON come l’esempio qui sotto:
