Use Case Recommendations
Best for: OpenParser
OpenParser is a document-parsing API whose selling point is model choice rather than a single house OCR engine. Nine hosted OCR models sit behind one request shape: PaddleOCR-VL, two generations of Mistral OCR, Azure Document Intelligence Layout and Read, Google enterprise document engines and AWS Textract among them. You change the `ocr_model` field and nothing else about your integration, which is a direct answer to the usual failure mode of document pipelines — the engine you standardised on turns out to be wrong for one document class and switching means rewriting the integration. Two endpoints carry the product. POST /parse returns a typed `openparser@1` block structure plus markdown, where blocks carry a kind (text, table, field, checkbox, signature), page number, bounding box and confidence. POST /extract fills a schema you supply and cites the block ids each value came from, so a downstream reviewer can trace any extracted field back to its position on the page. Sync, async and batch requests share the same request shape, with GET /jobs/{id} for async status and GET /files/{id}/content for reusable file bytes. Idempotency keys are supported on parse. Pricing is per page and published per model, which makes cost routing an explicit design decision: send bulk general documents to the cheapest open-weight engine and reserve the expensive enterprise engines for the layout-heavy exceptions.
Ideal use cases:
- •Teams or individuals who need nine hosted ocr engines swappable via one request field
- •Teams or individuals who need typed openparser@1 blocks with bounding boxes and confidence scores
- •Teams or individuals who need schema extraction that cites the source block id for every value
- •Teams or individuals who need sync, async and batch share one request shape
- •Anyone focused on ocr workflows
- •Anyone focused on document-parsing workflows
Best for: WebCrawler API
WebCrawler API crawls a whole site from a single request and returns clean Markdown built for LLM consumption — menus, footers, cookie banners and ads stripped before the content comes back, so what lands in a prompt or a vector index needs no second cleanup pass. Three endpoints cover the range: scrape for one page, crawl for a whole site with an item limit, and an agent mode for tasks that need navigation. The infrastructure it absorbs is the actual value: residential proxies, automatic retries, rate-limit handling, real headless browsers, JavaScript rendering, CAPTCHA solving and anti-bot bypass, with each request routed down the fastest path likely to succeed. Smart caching returns frequently requested pages in under a second instead of several, with a max_age parameter to force a fresh fetch. The feature worth singling out is change detection: you set up a feed for a site and receive only what changed — added pages, removed entries, structural changes and full diffs — instead of running polling loops that re-fetch and re-tokenise unchanged content, which is the expensive default for anyone keeping a documentation index current. SDKs cover Node, Python, PHP, .NET and Java, plus cURL and an AI-agent path, and there are no-code guides for Zapier, Make, n8n and Integrately. Billing is per successful request only.
Ideal use cases:
- •Teams or individuals who need whole-site crawl from a single request
- •Teams or individuals who need clean llm-ready markdown with boilerplate stripped
- •Teams or individuals who need managed proxies, retries, headless browsers and captcha handling
- •Teams or individuals who need smart caching with a max_age bypass
- •Anyone focused on crawling workflows
- •Anyone focused on markdown workflows
