It provides four core web-interaction tools: real-time web search (tavily-search), intelligent data extraction from web pages (tavily-extract), structured website mapping, and systematic web crawling. The agent accepts a natural-language prompt via a simple POST body and returns a text response.\n\nPayment is handled through the x402 protocol on the Base Sepolia testnet, using USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a maximum charge of 100,000 units per request. The endpoint requires an X-PAYMENT header conforming to x402 version 1. The maximum request timeout is 1,200 seconds (20 minutes), which suggests that crawl or map operations may take significant time.\n\nDocumentation is minimal. There is no OpenAPI spec, no dedicated docs page, and no detailed schema beyond the x402 challenge payload. The input is a single string field (\"input\") and the output is a single string field (\"response\"). All capability claims come from the x402 challenge description; no independent verification of tool availability or response format is possible from the provided material.","tags":[],"capabilities":["web-search","web-extract","web-crawl","site-mapping","tavily-tools","x402-payment","base-sepolia","usdc-payment","natural-language-input"],"categories":["search","web-scraping"],"synonyms":["tavily search","web scraper","web crawler","site mapper","web extraction","tavily MCP","real-time search API","web data extraction","questflow tavily"],"warnings":["Payment is on Base Sepolia testnet — not suitable for production use","No OpenAPI or documentation endpoint found (404 on /docs, /api, /README)","Output schema is a single opaque string; no structured tool-level responses documented","All capability claims (search, extract, map, crawl) come solely from the x402 challenge description and are unverified","Maximum timeout of 1200 seconds suggests potentially very long response times"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68ee165dd8b26d2e2dffa01c","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0xcD5CAc332866383842e5d48C4c40A606B5D8DA79","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68ee165dd8b26d2e2dffa01c","description":"The Tavily MCP server provides:\nsearch, extract, map, crawl tools\nReal-time web search capabilities through the tavily-search tool\nIntelligent data extraction from web pages via the tavily-extract tool\nPowerful web mapping tool that creates a structured map of website\nWeb crawler that systematically explores websites\n | Powered by Questflow","outputSchema":{"input":{"type":"http","method":"POST","bodyFields":{"input":{"type":"string","required":true,"description":"Your message to the agent"}},"discoverable":true},"output":{"response":{"type":"string","required":true,"description":"Response from the agent"}}},"maxAmountRequired":"100000","maxTimeoutSeconds":1200}]},"qualityScore":"0.250","qualityRationale":"No OpenAPI spec, no docs endpoint, no examples, and no independent verification of tool behavior.
