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 search query, result count, source identifier ('wikipedia-search-en'), and an array of ranked results — each with a Wikipedia article title, full article URL (en.wikipedia.org), and a short text snippet. Also includes a note reminding the caller to use /wiki/lookup for full intro extracts.
Example use cases
Fact-checking background on a topic
“Search Wikipedia for 'mRNA vaccines' and return the top 5 articles with titles and snippets so I can verify what the encyclopedia says.”
Research starting point for an essay
“Find the top 10 Wikipedia articles about 'the French Revolution' — I need titles, URLs, and brief snippets to decide which ones to read.”
Disambiguation between similar topics
“Search Wikipedia for 'Mercury' and show me the top 5 results so I can see if it's returning articles about the planet, the element, or the Roman god.”
Technical details
Endpoint
GEThttps://payload402.edgebytenet.workers.dev/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a ranked list of Wikipedia articles matching a query — especially when you want SERP-style output (multiple titles, URLs, snippets) rather than a single article's content. Prefer this over /wiki/lookup when you don't know the exact article title and need to discover relevant articles first. It is Wikipedia-only (not the open web), so prefer a general web search API if you need broader coverage.
Side effects
- Missing required 'q' parameter returns an error
- Query exceeding 400 characters may be rejected or truncated
- Count parameter outside 1–10 range is invalid
- No results found for highly obscure or misspelled queries
- MediaWiki search downtime causes upstream failures
- Payment of 0.005 USDC not completed results in 402 response
