Using Parsers

Parsers are a way to turn unstructured data in structured data that is compatible with your backend. Combining parsers with the Olostep API (crawls, scrapes, batches) allows to turn any website into an API call to return the JSON you need. Parsers are ideal when you need data at scale in a recurrent way from the same websites. This approach is significantly more cost-efficient and fast compared to LLM extract and returns only the required JSON. We offer pre-built parsers for popular websites and use cases. You can also create your own parsers in a few minutes with LLMs using the dashboard or ask our team to do it for you.

Quick reference for AI agents

Endpoint: POST https://api.olostep.com/v1/scrapes (also /v1/batches and /v1/crawls) (auth: Authorization: Bearer <YOUR_API_KEY>)
Required: url_to_scrape, formats: ["json"], parser: { "id": "@olostep/..." }
Pre-built parser ids: @olostep/google-search, @olostep/amazon-it-product, @olostep/extract-emails, @olostep/extract-calendars, @olostep/extract-socials
Batches / crawls: batches take parser: { "id": "..." }; crawls take the id as a string in scrape_options.parser
Returns: result.json_content (stringified JSON — parse it) and result.json_hosted_url
Sync or async: Sync on /v1/scrapes; async on batches and crawls (fetch with GET /v1/retrieve?retrieve_id=...&formats=json)
Use instead: one-off pages or changing layouts → LLM extraction

Pre-Built Parsers

We offer several pre-built parsers for popular websites:

Google Search: @olostep/google-search
Amazon Product: @olostep/amazon-it-product
Extract Email: @olostep/extract-emails
Extract Calendars: @olostep/extract-calendars
Extract Socials: @olostep/extract-socials
TikTok data extraction: get in touch with us to get the parser ID
Google News: get in touch with us to get the parser ID
Google Maps: get in touch with us to get the parser ID

Example Usage

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))

Response Format

When you make a request to the Olostep API with the parser format, you’ll receive a JSON response like the example below:
