Each spin awards between 2,000 and 224,000 XP within the BaseHub ecosystem, with a chance at a \"MEGA JACKPOT.\" The endpoint is restricted to holders of the BaseHub Early Access NFT Pass.\n\nThe endpoint lives at `https://basehub-alpha.vercel.app/api/x402-nft-wheel` and accepts POST requests. Payment is settled on Base mainnet using USDC (contract `0x8335…2913`) via the x402 exact-payment scheme. The x402 challenge advertises a `maxAmountRequired` of 50,000 base units (USDC has 6 decimals → $0.05) with a 600-second payment timeout. The payee address is `0x7d2Ceb7a0e0C39A3d0f7B5b491659fDE4bb7BCFe`.\n\nBaseHub is a multi-chain Web3 hub supporting Base, InkChain, Soneium, Tempo, Katana, MegaETH, and several testnets. It offers token launches, DEX aggregation, NFT minting, prediction markets, smart-contract analysis, and various XP-earning mini-games. The NFT Wheel and a companion NFT Plinko game are the platform's x402-enabled features. No OpenAPI schema or detailed API documentation was found; the request/response format must be inferred from the x402 challenge metadata alone.","tags":[],"capabilities":["x402-payment","usdc-base","nft-gated","xp-rewards","wheel-of-fortune","gamification","post-endpoint"],"categories":["gaming","blockchain"],"synonyms":["NFT wheel of fortune","BaseHub wheel","x402 spin game","USDC wheel spin","Base chain game","XP wheel","crypto wheel"],"warnings":["No OpenAPI or request/response schema available; request body format is unknown.","Endpoint is NFT-gated: requires holding the BaseHub Early Access Pass NFT to use.","No dedicated API documentation found; /docs, /api, /pricing, and /README all return only a chat-assistant shell.","Platform is labeled BETA; availability and behavior may change without notice."],"endpointUrl":"https://basehub-alpha.vercel.app/api/x402-nft-wheel","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x7d2Ceb7a0e0C39A3d0f7B5b491659fDE4bb7BCFe","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://basehub-alpha.vercel.app/","description":"BaseHub NFT Wheel - Pay 0.05 USDC","outputSchema":{"input":{"type":"http","method":"POST","discoverable":true}},"maxAmountRequired":"50000","maxTimeoutSeconds":600}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear, but there is no OpenAPI schema, no documented request/response format, no examples, and the endpoint is NFT-gated so actual functionality cannot be verified without holding the pass.
