Diffbot Web Search API is one of 10 APIs that [Diffbot](https://apis.io/providers/diffbot/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Search, Web, Index, and Retrieval. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

Search Diffbot's own web index — the largest independently crawled index outside Google and Bing, over 150TB. Candidates are retrieved and reranked by a cross-encoder trained to favour factual relevance over popularity and primary sources over secondary ones, and the most relevant chunk of each page is returned inline for citation. This is the one Diffbot surface that authenticates with an Authorization Bearer header rather than a token query parameter.
