Diffbot
Diffbot uses AI models to turn unstructured web content into linked knowledge through a set of data services. Extract classifies a page and returns structured JSON using a standard page type and ontology. Crawl starts with seed URLs, visits sites, and collects extracted pages in structured datasets. Natural Language resolves entities, relationships, coreferences, salience, and sentiment in plain text. The Knowledge Graph supports structured queries about companies, people, news, and other public web entities. Web Search provides an API and a self-hostable search index for a machine or cloud, including offline use; Diffbot says closed media sites such as Facebook, Reddit, LinkedIn, and Instagram are generally off limits. Python and TypeScript libraries and agent skills are listed as interfaces. The free plan provides 10,000 credits per month, all four APIs, and up to 5 requests per minute without a credit card. It returns a 429 Quota Exceeded response after the credit allowance or rate limit is reached, with quotas resetting at the start of each billing period. Startup costs $299 a month. Diffbot lists API, self-hosted, and web platforms.
