How this service works

Natural language processing — NER, sentiment, facts, summarization.

Output

A JSON object containing the requested NLP fields (entities, sentiment, facts, categories, sentences, summary, language) for each submitted document, along with payment confirmation showing 0.001 USDC settled and a request ID for status tracking.

Example use cases

Customer review sentiment analysis

“Run sentiment analysis and extract any named entities from these customer reviews — I want to know if people are happy and what products or brands they mention: 'The Nike Air Max was fantastic, delivered super fast by FedEx!'”

News article entity extraction

“Pull out all the people, organizations, and locations mentioned in this news article, and give me a one-paragraph summary of what it's about: 'President Biden met with EU leaders in Brussels to discuss trade policy and energy security amid rising tensions with Russia.'”

Multi-document fact extraction

“I have three research documents I'd like you to process — extract the key facts and categorize each one, and also detect whether they're written in English or another language.”

When to prefer

Choose this endpoint when you need multi-faceted NLP analysis (entities + sentiment + facts + summary in one call) powered by Diffbot's knowledge graph, billed at a low $0.001 USDC per call via x402 micropayment — ideal for agents that need structured text intelligence without managing API keys or subscriptions, and when you want Diffbot's specific NER and fact-extraction quality rather than a generic LLM summarization.

Side effects

Invalid or missing 'content' field returns an error with no NLP output
Unsupported 'fields' values may be silently ignored or cause a parsing error
Payment failure via x402 protocol results in a 402 response and no analysis
Very large documents may exceed processing limits or increase latency
Malformed document objects in the content array may cause partial or failed extraction
