Wikipedia on xpay — Agent-native article search and retrieval, billed per call

Wikipedia is the world's largest free online encyclopedia, and developers often need programmatic access to search articles, extract content, and retrieve citations. Rather than building custom scrapers or managing Wikipedia's own API, xpay wraps Wikipedia's capabilities as MCP tools—callable directly from Claude Code, Cursor, VS Code, and other MCP-compatible agents. You authenticate once with your xpay key; xpay handles the upstream connection. Each call costs $0.01, with no subscription or per-provider signup required.

See the official Wikipedia for more context on the encyclopedia itself.

What's available

• search — Find articles by keyword with optional filtering and sorting. Useful for discovery and research workflows.
• get_page — Retrieve complete page metadata, content preview, and citations summary in one call.
• get_page_content — Extract article text without citations or metadata overhead.
• get_page_citations — Fetch the citations list for fact-checking and source attribution.
• get_related_pages — Discover linked articles from a given page for exploratory research.
• get_page_section — Extract a specific section by header name (e.g., "History", "See also").
• get_page_sections — List all section headers in an article for navigation and selective retrieval.

When Wikipedia is the right tool

• Research and fact-checking: Agents need to verify claims or gather background information on topics, people, places, or events.
• Content enrichment: Augment your application with summaries, definitions, or related links from a trusted source.
• Knowledge base queries: Build chatbots or Q&A systems that cite Wikipedia as a reference.
• Citation and source tracking: Extract citations to validate information or link users to primary sources.
• Educational tools: Create study aids, flashcards, or tutoring systems that pull from Wikipedia's corpus.

When to choose something else

• Real-time news or breaking events: Wikipedia articles lag behind current events. Use a news API or web search for live updates.
• Specialized or niche domains: Wikipedia covers general knowledge well but may lack depth in proprietary, academic, or emerging fields. Consider domain-specific APIs or databases.
• High-volume, low-latency retrieval: If you need thousands of calls per second, per-call pricing may exceed a subscription model. Evaluate bulk licensing or direct API access.
• Structured data extraction: Wikipedia's semi-structured format requires parsing. For clean, normalized data (e.g., company financials, product specs), use dedicated data APIs.
• Non-English content at scale: While Wikipedia supports many languages, coverage and quality vary. Verify language availability for your use case.

Pricing snapshot

All Wikipedia tools on xpay cost $0.01 per call. No subscription, no overage fees—you pay only for what you use.

Quickstart

Install the Wikipedia MCP endpoint in Claude Code:

claude mcp add --transport http wikipedia "https://wikipedia.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

Replace YOUR_XPAY_KEY with your xpay API key (get one free at https://xpay.tools after email or Google signup).

Once connected, your agent can call tools by name—for example, ask Claude to "search for information on photosynthesis" and it will invoke the search tool with your query.

Alternatively, connect all xpay providers at once:

claude mcp add --transport http xpay "https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

With the unified endpoint, use xpay_discover to find Wikipedia tools, xpay_details to inspect their schemas, and xpay_run to execute them.

Why route Wikipedia through xpay?

• No Wikipedia signup: xpay holds the upstream credentials. You authenticate once with your xpay key and immediately access Wikipedia's full API.
• Pay-per-call, no subscription: Each call costs $0.01. No monthly fees, no commitment. Scale from one call to millions without changing your plan.
• MCP-native integration: Wikipedia tools appear as first-class MCP resources in Claude Code, Cursor, VS Code, and other compatible agents. No custom wrappers or SDK boilerplate.
• Unified billing across providers: Use Wikipedia alongside Tavily, Apollo, Perplexity, and other xpay providers. One invoice, one API key, one dashboard.
• Transparent pricing and usage: See exactly which tools you called, how many times, and what you owe. No hidden fees or surprise charges.
