Substack is served through the Universal Web Scraper API

You scrape Substack with Chocodata's Universal Web Scraper API: point it at any Substack URL and get the page back as structured JSON. Residential proxies, rotation, and retries are handled for you, with no Substack-specific setup. The same API key and credits work here as on every dedicated endpoint.

About Substack

Substack is a newsletter-publishing platform where writers run paid and free subscriptions, each on their own subdomain. An individual post page exposes the title, author, publication name, publish date, and article body that are useful to extract.

Scraping note: Posts live on per-publication subdomains and paid editions are partially truncated behind a subscriber paywall on the public page.

Example Substack page

https://example.substack.com/p/example-post-slug

Pass a URL like this as url= to the Universal Web Scraper API and get it back as JSON.

Fields you can extract from Substack

check_small post title check_small author name check_small publication name check_small publish date check_small post body text check_small subscriber-only flag

Common use: A newsletter-tracking tool scrapes Substack post pages to archive a writer's public essays along with publication and date metadata.

Everything you need to scrape Substack

Residential proxies keep your own IP out of every request, the JSON comes back clean, and 1,000 free requests a month let you prove substack scraper works before you add a card.

data_object

Clean structured JSON

The Substack page comes back as JSON in the parse mode you choose: auto, html, text, or json. No selectors to maintain for substack scraper.

gpp_good

Bypasses CAPTCHAs and anti-bot defenses

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

Substack Scraper API FAQ

Is it legal to scrape Substack?

expand_more
Scraping publicly accessible Substack 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 Substack'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 Substack without getting blocked?

expand_more
You scrape Substack without getting blocked by sending the URL to the Universal Web Scraper API, which fetches it through rotating residential proxies and retries on soft blocks. Your own IP is never used, so Substack's anti-bot layer sees ordinary residential traffic instead of a server.

What data does the Substack Scraper API return?

expand_more
Through the Universal Web Scraper API you get the Substack page back as JSON: rendered HTML, plain text, or auto-parsed content depending on the parse mode you pass. You choose the URL, Chocodata returns the data.

How much does the Substack Scraper API cost?

expand_more
The Substack 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 Substack account or login?

expand_more
No Substack login is needed for public pages. You point the Universal Web Scraper API at a publicly accessible Substack URL with your Chocodata API key; you do not hand over any Substack credentials. Login-gated content is not supported.
