Diffbot

What it does

Diffbot reads public web pages, whole sites, plain text and entity queries and returns structured JSON, graph-linked facts and search results. Its Extract API classifies a single URL into structured data without rules, the Crawl API walks a site from a seed URL into a dataset, and the Natural Language API resolves entities, relationships, facts and sentiment from text.

Companies use Diffbot to structure product data for shopping search, to drive predictive business development from organization data, and to surface supply chain insights from news. Extracted facts are linked to each other like nodes in a graph, so the same entity resolves consistently across sources. A web search API is also offered, built for self-hosting and API access.

Diffbot suits developers and teams that need programmatic access to public web data at scale. The Free plan needs no credit card and includes 10,000 credits per month at 5 requests per minute, while paid plans bill usage beyond included credits. Students and academic researchers get Startup-tier access free of charge. Enterprise volume and pricing are arranged through sales.

What it can do

Before you choose

• Credits vary by action: 1 credit per page extracted, 25 per Knowledge Graph entity exported, and 0 for crawl spidering; Crawl access starts on the Plus plan.
• The Free plan returns a 429 Quota Exceeded response once 10,000 credits or the rate limit is reached; quotas reset at the start of each billing period.
