How this service works
Agent data gateway plus the live x402 market feed. Normalized, schema-stable JSON for crypto prices, DeFi TVL, on-chain DEX pools, gas, FX, US Treasury yields, US weather, WHOIS, DNS, email validation, web-page extraction, tech news, Wikipedia, npm/PyPI package health, ERC-20 token-risk scoring, and composed domain dossiers, plus x402 ecosystem analytics and metered LLM inference. Pay per call with USDC via the x402 protocol; no accounts, no API keys.
Output
Returns a JSON object with ok:true and a data object containing: kind (e.g. 'standard'), language, title, a plain-text extract (summary paragraph), a short description, the canonical Wikipedia page URL, a thumbnail image URL, and the Wikibase item ID. Also includes metadata: whether the result was cached, the source name, the fetch timestamp, and CC BY-SA 4.0 attribution notice.
Example use cases
Biography lookup for research
“Give me the Wikipedia summary for Marie Curie — her description, a short extract about her life, and the link to her Wikipedia article.”
Concept explanation for content enrichment
“Fetch the Wikipedia entry for 'quantum entanglement' so I can include a plain-English extract and a link in my newsletter.”
Entity disambiguation for data pipeline
“Look up the Wikipedia page for 'Python programming language' and return the extract, description, and Wikibase item ID so I can tag it in my knowledge graph.”
Technical details
Endpoint
GEThttps://gateway.stride20k.com/knowledge/wiki/%7Btitle%7DWhen to prefer
Choose this endpoint when you need structured, schema-stable Wikipedia summaries (extract, description, thumbnail, Wikibase ID) in a single pay-per-call request with no API key setup. Prefer it over raw Wikipedia REST API calls when you want normalized JSON with consistent fields, or when operating in an x402 USDC payment environment with other Stride20k data endpoints (crypto prices, DeFi, DNS, etc.) and want a unified gateway. Not ideal if you need full article wikitext, revision history, or multi-language batch lookups.
Side effects
- Article not found for the given title returns an error or empty data
- Ambiguous title may return an unexpected article — agent should verify title matches intended subject
- Non-English titles may need exact Wikipedia spelling to resolve correctly
- Network or upstream Wikipedia API outage may cause fetch failure
- Payment failure via x402 protocol will block the request before it reaches Wikipedia
