It returns a leaderboard of top trader wallets along with buy/sell flow analysis and accumulation patterns, augmented with AI-generated insights. The data is sourced via Bitquery and processed through Einstein AI's analytical layer.\n\nThe endpoint supports querying across Ethereum, Base, BSC, Arbitrum, Polygon, Optimism, and Solana, with Base as the default chain. Optional parameters include result limit (up to 500), and time period ranging from 1 hour to 30 days. Each request costs $1.00 paid via the x402 protocol using USDC on Base, USDC on Solana, or BTC via Lightning Network. No API keys are required — payment is handled entirely through the X-PAYMENT header with a signed authorization.\n\nThe response includes structured data about top-performing wallets, an AI-powered analysis section with insights and patterns, and a payment receipt. The endpoint is part of Einstein AI's broader suite of 20+ blockchain intelligence endpoints covering market data, whale tracking, launchpad monitoring (Pump.fun, Zora), security audits (rug pull detection, MEV detection), DeFi arbitrage scanning, and comprehensive investment reports, all priced between $0.25 and $1.15 per request.","tags":[],"capabilities":["smart-money-tracking","wallet-profitability-analysis","buy-sell-flow-analysis","accumulation-pattern-detection","multi-chain-support","ai-analysis","x402-payment","bitquery-data","whale-intelligence"],"categories":["blockchain","defi","analytics"],"synonyms":["smart money tracker","profitable wallet finder","top traders leaderboard","whale wallet tracker","on-chain alpha","smart money wallets","trading pattern analysis","wallet PnL tracker","dex trader ranking"],"warnings":["The /api route returned a Cloudflare 522 (origin timeout) during crawl, suggesting occasional backend availability issues.","Response body structure is inferred from the generic BitqueryResponse schema — actual field names in the 'data' object are not documented per-endpoint.","The example_response_json is illustrative based on the schema; no real response sample was captured."],"endpointUrl":"https://emc2ai.io/x402/bitquery/smart-money","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xc9368b30BD620164FD1a05a5d99dcaf8Ae754775","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://emc2ai.io/x402/bitquery/smart-money","description":"Leaderboard of top trader wallets with buy/sell flow analysis and accumulation patterns.
