DataSonar API is live in production
Clean structured data
from any site.
One API key, one endpoint pattern, every major site you care about — plus a built-in intelligence layer that returns the WHOIS, SSL, tech stack, and contacts behind every domain in the same call.
No credit card required. 1,000 requests free, every month.
Outcomes, not parsing
Send a URL, get the data — markdown for LLMs, JSON-LD for analytics, vertical-specific schemas for Amazon, Zillow, and Google Maps.
The whole web, indexed
One endpoint family covers every site. Smart routing skips the browser when a page does not need it, so static pages return in milliseconds.
Intelligence in every call
DNS, WHOIS, SSL, technology stack, email verification, and contact extraction — all together, all in JSON.

Frequently asked questions
What kinds of sites can DataSonar handle? ▾
DataSonar handles static pages, JavaScript-heavy single page applications, e-commerce sites, real estate listings, maps, and most content behind anti-bot defenses. For sites with the strongest protection — Amazon, Zillow, certain travel and ticketing sites — pairing your request with a residential proxy improves success rates significantly.
How is DataSonar different from Apify, ScraperAPI, or Bright Data? ▾
Apify pioneered the marketplace model for scrapers and ScraperAPI nailed developer ergonomics. DataSonar takes the same simplicity and goes further on two fronts: every extractor is maintained in-house so reliability stays consistent across the catalog, and a complete domain intelligence layer — DNS, WHOIS, SSL, tech stack, contacts — ships in the same API at no extra cost.
Do you charge for failed requests? ▾
No. Failed requests do not count against your monthly quota. You only pay for successful responses.
What does the free tier include? ▾
1,000 requests every month, every endpoint, no credit card. Plenty to evaluate the API end to end and run real prototypes.
How do I scrape Amazon or Zillow specifically? ▾
Use the dedicated actor endpoints —
/v1/actors/amazon and /v1/actors/zillow. They return structured product or property data in a clean JSON schema. Both sites use aggressive anti-bot defenses, so we recommend supplying a residential proxy parameter for production workloads.Can DataSonar scrape pages that require login? ▾
Yes, via the
actions array on /v1/scrape. You can drive clicks, typing, waits, and form submissions natively. For pages that need persistent sessions, talk to us about the enterprise tier.What is the average response time? ▾
Static pages typically return in under 800 milliseconds. JavaScript-rendered pages take 1.5 to 4 seconds depending on complexity. Domain intelligence calls return in 50 to 500 milliseconds.
Is the API rate-limited? ▾
Yes. Each plan has a requests-per-minute ceiling and a monthly request quota. Rate limit headers are returned with every response so your client can adapt in real time.
