It accepts a natural-language text input and returns agent-generated responses covering token information lookup by contract address, comprehensive market data retrieval, price tracking with market metrics, and identification of top gaining and losing coins. It also offers DeFi pool analysis across multiple networks, fetches trending coins, NFTs, and categories, and includes Twitter management capabilities such as posting, replying, retweeting, monitoring mentions, and searching tweet content.\n\nPayment is handled via the x402 exact-payment scheme on Base Sepolia using USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e), with a maximum charge of 500,000 units (0.50 USDC assuming 6 decimals) per request. The endpoint accepts HTTP POST with a JSON body containing a single \"input\" string field and returns a JSON object with a \"response\" string field. The maximum timeout per request is 1,200 seconds (20 minutes), suggesting the agent may perform multi-step tool calls behind the scenes.\n\nThis is a development-stage endpoint (api-dev subdomain, Base Sepolia testnet) powered by Questflow's AI agent swarm platform. No OpenAPI spec, dedicated documentation page, or usage examples beyond the x402 challenge metadata were found. Prospective users should treat this as an experimental/dev service and verify behavior before relying on it in production.","tags":[],"capabilities":["crypto-token-lookup","market-data-retrieval","price-tracking","top-gainers-losers","defi-pool-analysis","trending-coins","trending-nfts","twitter-post","twitter-reply","twitter-retweet","twitter-mention-monitoring","twitter-search","x402-payment","natural-language-input"],"categories":["crypto","defi","social-media"],"synonyms":["cryptocurrency data API","DeFi analytics","token price tracker","trending crypto coins","crypto market analysis","Twitter bot agent","Web3 trading agent","Questflow swarm"],"warnings":["Development endpoint (api-dev subdomain) on Base Sepolia testnet — not production-ready","No OpenAPI or documentation found; /docs, /api, /pricing, /README all return 404","Response schema is a single unstructured string — output format is unpredictable","20-minute max timeout suggests potentially slow or multi-step agent execution","Example response is entirely inferred; no real response data was available"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f5afdeb496db62cf747cf9","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x6F8FeeA520A580feA5fa672B78cBaBB6a1Dd7dc8","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f5afdeb496db62cf747cf9","description":"Web3 Trader provides real-time cryptocurrency data aggregation and analysis, including token information lookup by contract address, comprehensive market data retrieval, price tracking with market metrics, and identification of top gaining/losing coins.
