gpp_good

Bypasses CAPTCHAs and anti-bot defenses

We get past CAPTCHAs, IP rate limiting, IP blocking, and headless-browser detection on Open Library using rotating, country-matched residential proxies, so requests look like real users and your own IP stays private.

api

One API call

The Open Library Scraper API is one simple API call. The same key works across our whole web scraping API: all 235 targets, any language, no SDK required.

travel_explore

Geo-targeting and JS rendering

Pass a country for proxy geo-targeting and turn on JavaScript rendering when a Open Library page needs it. open library data api handles dynamic content and region-locked results.

Scrape Open Library in one API request

Send one API request to the Open Library Scraper API and read back typed fields. Chocodata routes the request through country-matched residential proxies, retries soft blocks, and parses the page, so open library api stays reliable as Open Library's markup shifts.

Open Library Scraper API FAQ

Is it legal to scrape Open Library?

expand_more
Scraping publicly accessible Open Library data is generally legal in the US under the Ninth Circuit's hiQ v. LinkedIn ruling, which held that scraping public web data does not violate the Computer Fraud and Abuse Act. It does not override Open Library's own Terms of Service, which are a contract matter, so check those for your use case and comply with data laws such as GDPR. This is general information, not legal advice.

How do I scrape Open Library without getting blocked?

expand_more
You scrape Open Library without getting blocked by letting Chocodata route every request through country-matched residential proxies with automatic rotation and retries. Because the traffic looks like real users from real networks, the Open Library Scraper API gets through anti-bot defenses that block datacenter IPs, and you never expose your own address.

What data does the Open Library Scraper API return?

expand_more
The Open Library Scraper API returns Open Library book data as structured JSON: the core fields parsed from the page, ready to store or query. Exact fields depend on the book type, and only successful (2xx) responses are billed.

How much does the Open Library Scraper API cost?

expand_more
The Open Library Scraper API costs nothing to start: the Free plan includes 1,000 requests per month (5,000 credits) across all 235 targets. After that, monthly plans begin at $19, or you top up pay-as-you-go at $0.90 per 1,000 successful requests. One request is 5 credits, and non-2xx responses are never charged.

Do I need a Open Library account or login?

expand_more
No Open Library account or login is required. The Open Library Scraper API reads publicly accessible book pages, so you only need a Chocodata API key, not Open Library credentials. Pages that sit behind a Open Library login are out of scope.
