Olostep NodeJS SDK - Olostep Docs

NPM Package: olostep

Getting started

npm install olostep

import Olostep from 'olostep';

const client = new Olostep({apiKey: process.env.OLOSTEP_API_KEY});

// Minimal scrape example
const result = await client.scrapes.create('https://example.com');
console.log(result.id, result.html_content);

import Olostep from 'olostep';

const client = new Olostep({api_key: process.env.OLOSTEP_API_KEY});

// Minimal scrape example
const result = await client.scrapes.create('https://example.com');
console.log(result.id, result.html_content);

The NodeJS SDK accepts both camelCase and snake_case for all parameters. Use snake_case if you’re building for AI agents, it matches the API’s native field names.

Usage

Scraping

Scrape a single URL with various options:

import Olostep, {Format} from 'olostep';

const client = new Olostep({apiKey: 'your_api_key'});

// Simple scrape
const scrape = await client.scrapes.create('https://example.com');

// With multiple formats
const scrape = await client.scrapes.create({
  url: 'https://example.com',
  formats: [Format.HTML, Format.MARKDOWN, Format.TEXT],
  waitBeforeScraping: 1000,
  removeImages: true
});

// Access the content
console.log(scrape.html_content);
console.log(scrape.markdown_content);

// Get scrape by ID
const fetched = await client.scrapes.get(scrape.id);

import Olostep, {Format} from 'olostep';

const client = new Olostep({api_key: 'your_api_key'});

// Simple scrape
const scrape = await client.scrapes.create('https://example.com');

// With multiple formats
const scrape = await client.scrapes.create({
  url: 'https://example.com',
  formats: [Format.HTML, Format.MARKDOWN, Format.TEXT],
  wait_before_scraping: 1000,
  remove_images: true
});

// Access the content
console.log(scrape.html_content);
console.log(scrape.markdown_content);

// Get scrape by ID
const fetched = await client.scrapes.get(scrape.id);

Batch Processing

Process multiple URLs in a single batch:

// Using URL strings (custom IDs auto-generated)
const batch = await client.batches.create([
  'https://example.com',
  'https://example.org',
  'https://example.net'
]);

// Or with explicit custom IDs
const batch = await client.batches.create([
  {url: 'https://example.com', customId: 'site-1'},
  {url: 'https://example.org', customId: 'site-2'}
]);

console.log(`Batch ${batch.id} created with ${batch.total_urls} URLs`);

// Wait for completion
await batch.waitTillDone({
  checkEveryNSecs: 5,
  timeoutSeconds: 120
});

// Get batch info
const info = await batch.info();
console.log(info);

// Stream individual results
for await (const item of batch.items()) {
  console.log(item.custom_id);
}

// Using URL strings (custom IDs auto-generated)
const batch = await client.batches.create([
  'https://example.com',
  'https://example.org',
  'https://example.net'
]);

// Or with explicit custom IDs
const batch = await client.batches.create([
  {url: 'https://example.com', custom_id: 'site-1'},
  {url: 'https://example.org', custom_id: 'site-2'}
]);

console.log(`Batch ${batch.id} created with ${batch.total_urls} URLs`);

// Wait for completion
await batch.waitTillDone({
  check_every_n_secs: 5,
  timeout_seconds: 120
});

// Get batch info
const info = await batch.info();
console.log(info);

// Stream individual results
for await (const item of batch.items()) {
  console.log(item.custom_id);
}

Crawling

Crawl an entire website:

const crawl = await client.crawls.create({
  url: 'https://example.com',
  maxPages: 100,
  maxDepth: 3,
  includeUrls: ['*/blog/*'],
  excludeUrls: ['*/admin/*']
});

console.log(`Crawl ${crawl.id} started`);

// Wait for completion
await crawl.waitTillDone({
  checkEveryNSecs: 10,
  timeoutSeconds: 300
});

// Get crawl info
const info = await crawl.info();
console.log(`Crawled ${info.pages_crawled} pages`);

// Stream crawled pages
for await (const page of crawl.pages()) {
  console.log(page.url, page.status_code);
}

const crawl = await client.crawls.create({
  url: 'https://example.com',
  max_pages: 100,
  max_depth: 3,
  include_urls: ['*/blog/*'],
  exclude_urls: ['*/admin/*']
});

console.log(`Crawl ${crawl.id} started`);

// Wait for completion
await crawl.waitTillDone({
  check_every_n_secs: 10,
  timeout_seconds: 300
});

// Get crawl info
const info = await crawl.info();
console.log(`Crawled ${info.pages_crawled} pages`);

// Stream crawled pages
for await (const page of crawl.pages()) {
  console.log(page.url, page.status_code);
}

Site Mapping

Generate a sitemap of URLs from a website:

const map = await client.maps.create({
  url: 'https://example.com',
  topN: 100,
  includeSubdomain: true,
  searchQuery: 'blog posts'
});

console.log(`Map ${map.id} created`);

// Stream URLs
for await (const url of map.urls()) {
  console.log(url);
}

// Get map info
const info = await map.info();

const map = await client.maps.create({
  url: 'https://example.com',
  top_n: 100,
  include_subdomain: true,
  search_query: 'blog posts'
});

console.log(`Map ${map.id} created`);

// Stream URLs
for await (const url of map.urls()) {
  console.log(url);
}

// Get map info
const info = await map.info();

AI-Powered Answers

Get answers from web pages using AI:

import Olostep from 'olostep';

const client = new Olostep({apiKey: 'your_api_key'});

// Simple task: pass a string directly
const answer = await client.answers.create(
  'What is the main topic of https://example.com?'
);
console.log(answer.answer);
console.log(answer.sources);

// With structured JSON output
const structured = await client.answers.create({
  task: 'Extract all product names and prices from https://example.com',
  jsonFormat: {
    products: [{name: '', price: ''}]
  }
});
console.log(structured.json_content);

// Retrieve a previously created answer by ID
const fetched = await client.answers.get(answer.id);
console.log(fetched.answer);

import Olostep from 'olostep';

const client = new Olostep({api_key: 'your_api_key'});

// Simple task: pass a string directly
const answer = await client.answers.create(
  'What is the main topic of https://example.com?'
);
console.log(answer.answer);
console.log(answer.sources);

// With structured JSON output
const structured = await client.answers.create({
  task: 'Extract all product names and prices from https://example.com',
  json_format: {
    products: [{name: '', price: ''}]
  }
});
console.log(structured.json_content);

// Retrieve a previously created answer by ID
const fetched = await client.answers.get(answer.id);
console.log(fetched.answer);

Content Retrieval

Retrieve previously scraped content:

// Get content in specific format(s)
const content = await client.retrieve(retrieveId, Format.MARKDOWN);
console.log(content.markdown_content);

// Multiple formats
const content = await client.retrieve(retrieveId, [
  Format.HTML,
  Format.MARKDOWN
]);

Advanced Options

Custom Actions

Perform browser actions before scraping:

const scrape = await client.scrapes.create({
  url: 'https://example.com',
  actions: [
    {type: 'wait', milliseconds: 2000},
    {type: 'click', selector: '#load-more'},
    {type: 'scroll', distance: 1000},
    {type: 'fill_input', selector: '#search', value: 'query'}
  ]
});

Geographic Location

Scrape from different countries using predefined country codes or any valid country code string:

import Olostep, {Country} from 'olostep';

const client = new Olostep({apiKey: 'your_api_key'});

// Using predefined enum values (US, DE, FR, GB, SG)
const scrape = await client.scrapes.create({
  url: 'https://example.com',
  country: Country.DE  // Germany
});

// Or use any valid country code as a string
const scrape2 = await client.scrapes.create({
  url: 'https://example.com',
  country: 'jp'  // Japan
});

import Olostep, {Country} from 'olostep';

const client = new Olostep({api_key: 'your_api_key'});

// Using predefined enum values (US, DE, FR, GB, SG)
const scrape = await client.scrapes.create({
  url: 'https://example.com',
  country: Country.DE  // Germany
});

// Or use any valid country code as a string
const scrape2 = await client.scrapes.create({
  url: 'https://example.com',
  country: 'jp'  // Japan
});

Caching

By default, every scrape request fetches the page fresh (max_age: 0). Pass maxAge to reuse a recent result with the same parameters and improve response time. Value is in seconds; the maximum is 7 days (604800). See Caching for details.

const scrape = await client.scrapes.create({
  url: 'https://example.com',
  formats: ['markdown'],
  maxAge: 86400 // Accept results up to 1 day old
});

const scrape = await client.scrapes.create({
  url: 'https://example.com',
  formats: ['markdown'],
  max_age: 86400 // Accept results up to 1 day old
});

LLM Extraction

Extract structured data using LLMs:

const scrape = await client.scrapes.create({
  url: 'https://example.com',
  llmExtract: {
    schema: {
      title: 'string',
      price: 'number',
      description: 'string'
    },
    prompt: 'Extract product information from this page'
  }
});

const scrape = await client.scrapes.create({
  url: 'https://example.com',
  llm_extract: {
    schema: {
      title: 'string',
      price: 'number',
      description: 'string'
    },
    prompt: 'Extract product information from this page'
  }
});

Client Configuration

import Olostep from 'olostep';

const client = new Olostep({
  apiKey: 'your_api_key',
  apiBaseUrl: 'https://api.olostep.com/v1',  // optional
  timeoutMs: 150000,  // 150 seconds (optional)
