Endpoint
POSThttps://worlddata402.worlddata402.workers.dev/v1/wiki/summary/%7Blang%7D/%7Btitle%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured Wikipedia summary for a known entity (person, place, organization, concept) in a specific language, especially within an agent pipeline that uses x402 micropayments on Base mainnet. Prefer it over raw Wikipedia scraping when you want a clean, pay-per-use API abstraction without managing Wikipedia API credentials.
Side effects
- Article title not found in the specified language — returns a 404 or empty result
- Ambiguous title resolves to a disambiguation page — may return unhelpful summary
- Language code unsupported or malformed — returns an error
- Payment failure via x402 — call not executed, USDC payment rejected or insufficient balance
- Rate limiting or upstream Wikimedia API downtime — service temporarily unavailable
