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.","url":"https://payload402.edgebytenet.workers.dev/search?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET"],"type":"string"},"queryParams":{"type":"object","required":["q"],"properties":{"q":{"type":"string","description":"Search query (max 400 chars)"},"count":{"type":"integer","maximum":10,"minimum":1,"description":"Results 1–10 (default 10)"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"note":"Ranked English Wikipedia titles/snippets only (MediaWiki search) — not global web SERP; use GET /wiki/lookup for intro extract","count":2,"query":"x402 agents","source":"wikipedia-search-en","results":[{"url":"https://en.wikipedia.org/wiki/Cloudflare","title":"Cloudflare","snippet":"American technology company…"},{"url":"https://en.wikipedia.org/wiki/Payment_system","title":"Payment system","snippet":"Mechanism for transferring money…"}]}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_lZLdYWWyaO6xfwYZkpWxh","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Returns ranked English Wikipedia search results (titles, URLs, and snippets) using MediaWiki's search engine, formatted like a standard SERP JSON response.","exampleAgentPrompt":"Search Wikipedia for 'quantum entanglement' and give me the top 5 results — titles, URLs, and snippets — so I can pick the most relevant article.","exampleUseCases":[{"title":"Fact-checking background on a topic","prompt":"Search Wikipedia for 'mRNA vaccines' and return the top 5 articles with titles and snippets so I can verify what the encyclopedia says."},{"title":"Research starting point for an essay","prompt":"Find the top 10 Wikipedia articles about 'the French Revolution' — I need titles, URLs, and brief snippets to decide which ones to read."},{"title":"Disambiguation between similar topics","prompt":"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."}],"resultDescription":"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.
