How this service works
Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.
Output
Returns a JSON object containing the query string, Wikipedia title, short description, a longer extract (plain text summary), the Wikipedia URL, a thumbnail image URL, the Wikidata entity ID, and the source label ('Wikipedia').
Example use cases
UK company background check
“I'm researching Lloyds Banking Group — can you pull a factual summary of what the company does, where it's headquartered, and its Wikidata ID?”
Crypto project fact sheet
“Give me a quick knowledge summary of Ethereum — what it is, a brief description, and a link to its Wikipedia page if there is one.”
Entity enrichment for due diligence
“I need a structured factual overview of Rolls-Royce Holdings — title, description, and an extract from Wikipedia — to add to my research report.”
Technical details
Endpoint
GEThttps://api.trustedinformation.site/api/web/knowledgeWhen to prefer
Prefer this endpoint when you need a quick, structured factual summary of a named entity (UK company, crypto asset, or general topic) without signing up or managing API keys, and when you want to pay only for successful calls. It is especially useful for agent pipelines doing entity enrichment or due diligence on UK-centric subjects. For deep financial filings or real-time market prices, use a dedicated financial data API instead.
Side effects
- Query matches no Wikipedia/Wikidata entity — extract and title may be null
- Ambiguous entity name returns a generic or incorrect Wikipedia article
- Non-UK or obscure entities may have sparse or missing data
- Payment failure results in no charge and no data returned
- Rate or network errors may return HTTP 402 or 5xx with no body
