How this service works
npm package license triage for coding agents: call before npm install or adding a dependency mid-task. Returns declared license, SPDX normalization, and permissive-default compatible yes/no/unknown from the public npm registry. Triage only — not compliance-grade SBOM or legal advice. Workflow: call GET /license/check (or MCP check_npm_license) before npm install; if compatible=no, pick another package or escalate to human; if unknown, treat as risk. Example: left-pad@1.0.0 before install. Also: Convert amounts between ISO 4217 currencies using ECB daily reference rates (Frankfurter). Use for invoices, travel budgets, expense reports, and shopping comparisons when you need a verifiable rate instead of LLM arithmetic. Not live tradable FX — rates follow ECB business-day publication. Also: Resolve a place name or lat/lon to IANA timezone and coordinates (Open-Meteo). Use for agent scheduling, travel logistics, and local-time questions without LLM guessing. Not IP geolocation. Also: Translate short text between languages (Azure Translator). Use when an agent needs a verifiable string in another language for UI copy, messages, or research snippets — not legal, medical, or certified translation. Also: English Wikipedia fact lookup: search by query or exact title, returns intro extract as plain text. For agents that need a grounded summary before deeper web search. Not a substitute for primary sources. Also: Ranked search results (English Wikipedia): titles, article URLs, and snippets from MediaWiki search. Same SERP-shaped JSON as web search APIs; index is Wikipedia only — not the open web. Pair with GET /wiki/lookup for intro text.
Output
A JSON object containing the article title, page ID, plain-text introductory extract, the Wikipedia article URL, and a source label ('wikipedia-en'), plus a note to verify critical facts independently.
Example use cases
Grounding agent on a company
“Before we dive into analysis, pull the Wikipedia introduction for 'OpenAI' so I have a reliable background summary to work from.”
Quick fact check on a historical event
“What does Wikipedia say in its intro about the Battle of Thermopylae? Just the opening summary, plain text.”
Entity overview for a research brief
“Search Wikipedia for 'CRISPR gene editing' and give me the introductory extract so I can include a grounded definition in my report.”
Technical details
Endpoint
GEThttps://payload402.edgebytenet.workers.dev/wiki/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, plain-text factual grounding summary from English Wikipedia before performing deeper web research — especially when a single article intro is sufficient and you want a structured response with URL and page ID. Prefer over a full web search when you want a reliable, encyclopedic baseline for a well-known entity, concept, or event. Less suitable for obscure topics unlikely to have Wikipedia coverage, or when the most recent information is critical.
Side effects
- No matching Wikipedia article found for the given query or title — returns an error or empty result
- Ambiguous query matches a disambiguation page rather than a concrete article
- Wikipedia article exists but has no extractable intro text
- Both 'q' and 'title' omitted — missing required query parameter
- Rate limiting or upstream MediaWiki API unavailability
