It accepts a natural-language text input via POST and returns agent-generated responses. Capabilities described in the x402 challenge metadata include token information lookup by contract address, comprehensive market data retrieval, price tracking with market metrics, identification of top gaining and losing coins, DeFi pool analysis across multiple networks, and fetching trending coins, NFTs, and categories. It also includes Twitter/X management features such as posting, replying, retweeting, monitoring mentions, and searching tweet content.\n\nPayment is handled via the x402 protocol on Base Sepolia using USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a maximum amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC). The endpoint accepts an 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 is 1200 seconds, suggesting the agent may perform multi-step reasoning or external API calls before responding.\n\nNote that this endpoint is on a development domain (api-dev) and uses Base Sepolia (a testnet), indicating it is not yet in production. No OpenAPI spec, dedicated documentation, or pricing page was found. The underlying platform is Questflow, which markets itself as an AI agent economy for onchain market scanning and trading.","tags":[],"capabilities":["crypto-market-data","token-lookup","defi-pool-analysis","trending-coins","nft-trending","price-tracking","top-gainers-losers","twitter-posting","twitter-mentions","twitter-search","x402-payment","natural-language-input","base-sepolia-usdc"],"categories":["crypto","social-media","defi"],"synonyms":["cryptocurrency data API","DeFi analytics","token price tracker","crypto trending coins","Web3 agent","Twitter bot API","CoinGecko alternative","onchain market data","crypto market analysis","Questflow agent"],"warnings":["Endpoint is on a development domain (api-dev) and uses Base Sepolia testnet — not production-ready","No OpenAPI specification or documentation found; /docs, /api, /pricing, /README all return 404","Output schema is a single free-text string; no structured/typed response fields","maxTimeoutSeconds is 1200 (20 minutes), suggesting potentially very long response times","Response example is inferred — no actual sample response was available","Twitter management capabilities are self-described and unverified"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68ecc0ccd2f1fd7645d7e820","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x919aAa8A70da79f6184E6D0094E7F4BfB8aa65db","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68ecc0ccd2f1fd7645d7e820","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.
