Web Scraping {API}

A web scraping API is a service that extracts data from websites through a single HTTP request. Instead of building and maintaining your own scraping infrastructure — headless browsers for JavaScript rendering, rotating proxy pools, CAPTCHA handling, retry and backoff logic — you send the API a URL and get back clean, structured content. The API absorbs the adversarial parts of scraping so your integration stays a simple request and response.

The modern web makes this harder than it sounds. Most sites now render content client-side, so a plain HTTP fetch returns an empty shell. Bot-detection systems fingerprint requests and block datacenter IPs. Layouts change without notice and silently break hand-written selectors. A good scraping API absorbs all of that: it renders JavaScript when the page needs it, escalates through residential proxies when a request is blocked, and returns content in a format your code — or your model — can consume directly.

That last part matters more than it used to. LLMs process Markdown far more efficiently than raw HTML, which wastes tokens on tags, classes, and tracking noise. Context.dev's web scraping API was built for this era: every page comes back as clean GitHub Flavored Markdown by default, documents like PDF and DOCX are parsed into text, and an AI extraction endpoint returns structured JSON against a schema you define — no selectors to write, no parsers to maintain.

AI agents and RAG pipelines

The most common use case in 2026: giving a model live web access. Agents call the scrape endpoint to read pages mid-task; RAG pipelines crawl documentation sites and knowledge bases into vector stores. Markdown output keeps token costs down, and web context for LLMs stays fresh without re-engineering your ingestion.

Competitive and price monitoring

Scrape competitor pricing pages, product catalogs, and changelogs on a schedule, then diff the output. Because Markdown strips presentation noise, diffs reflect real content changes rather than markup churn — see website change monitoring.

Lead and company enrichment

Point the API at a prospect's domain and combine page content with the brand data endpoints— logos, colors, socials, address, and NAICS/SIC industry codes — to build enriched records that a generic scraper alone can't produce.

Search-grounded answers

The web search endpoint runs a query and scrapes each result to Markdown in one round-trip, so you can ground model answers in current sources without stitching together a search API and a scraper yourself.

Content migration and archiving

Full-site crawls convert legacy sites, wikis, and documentation into portable Markdown — useful for CMS migrations, compliance archives, and building corpora for fine-tuning.

You can absolutely scrape without an API — we've written guides to doing it well in Node.js and Python, and a roundup of the best open-source scraping tools. For a handful of friendly, static pages, a library and an afternoon are all you need.

The economics change at production scale. A scraper that works today breaks when the target site ships a redesign, adds Cloudflare, or starts fingerprinting datacenter IPs. Now you're maintaining browser farms, sourcing residential proxies, and writing retry logic — engineering time that compounds every month and differentiates nothing about your product. A web scraping API converts that maintenance burden into a metered bill: one request in, clean data out, and the anti-bot arms race is someone else's full-time job.

If you're comparing providers, we publish honest feature-by-feature breakdowns against Firecrawl, ScraperAPI, and ScrapingBee. The short version: most scraping APIs charge extra for JavaScript rendering and premium proxies; Context.dev includes both on every request and adds resolved brand and company data no pure scraper returns.

Sign up with a work email and get 500 free API credits at 30 requests per minute — enough for 500 Markdown scrapes; free-email signups get 250 credits at 10 requests per minute. Paid plans scale linearly per credit with no annual contract and no surprise multipliers for JavaScript rendering or stealth. Full details are on the pricing page.
