Check the particular request and provider terms for failure, free-tier and no-match handling.

It does not establish that a paid request delivered a correct answer. Monitoring, observed payments and provider output claims are separate evidence with different limits." }, { "question": "Does this listing prove an MCP client integration works?", "answer": "It identifies search-capable listings that advertise MCP and reviews their paid search routes. Confirm the server URL, transport, tools and payment behavior in the chosen client before relying on the integration." }, { "question": "Is an MCP tool list a search result?", "answer": "No. Tool discovery describes callable actions and arguments. A search invocation must return its own result or job state; keep discovery and paid task output separate." }, { "question": "Is an MCP label an endpoint-level guarantee?", "answer": "A provider may describe MCP for its broader tool collection. Inspect the specific tool schema and its underlying product rather than assuming a REST search route is automatically exposed to your client." }, { "question": "How should I handle asynchronous research?", "answer": "Store the job identifier and distinguish submission, progress and completion. Check whether retrieving the result requires another paid operation, and avoid repeatedly starting a job while waiting for the previous one." }, { "question": "Do MCP answers need source review?", "answer": "Yes. Protocol success does not establish factual support. Retain cited URLs and query settings, inspect relevant source material and keep generated summaries separate from source statements." } ], "services": [ { "name": "vaaya", "reseller_of_brand_via": null, "url": "https://x402-list.com/services/vaaya", "price_usd_per_call": 0.01, "networks": [ "Base" ], "uptime_30d": 100, "latency_ms": 451, "buyers_30d": 57, "last_checked_at": "2026-10-26T19:03:27.362Z", "what_it_does": "Provider advertises an MCP server with an Exa semantic web-search operation.", "generalist": true, "price_endpoint": { "method": "POST", "path": "/api/run/exa/search" }, "task_endpoints": [ { "method": "POST", "path": "/api/run/exa/search", "price_usd_per_call": 0.01 } ], "endpoints_listed": 7 }, { "name": "Tanod", "reseller_of_brand_via": null, "url": "https://x402-list.com/services/tanod", "price_usd_per_call": 0.007, "networks": [ "ARB", "Base", "POL", "SOL" ], "uptime_30d": 100, "latency_ms": 463, "buyers_30d": 26, "last_checked_at": "2026-10-26T19:10:06.486Z", "what_it_does": "Provider describes independent web-index results and advertises MCP access.", "generalist": true, "price_endpoint": { "method": "GET", "path": "/v1/search" }, "task_endpoints": [ { "method": "GET", "path": "/v1/search", "price_usd_per_call": 0.007 } ], "endpoints_listed": 6 }, { "name": "agdata", "reseller_of_brand_via": null, "url": "https://x402-list.com/services/agdata", "price_usd_per_call": 0.02285, "networks": [ "Base", "POL", "SOL" ], "uptime_30d": 100, "latency_ms": 57, "buyers_30d": 19, "last_checked_at": "2026-10-26T19:01:06.423Z", "what_it_does": "Provider separates Google discovery, news and search with bounded page text.", "generalist": true, "price_endpoint": { "method": "GET", "path": "/x402/google-search" }, "task_endpoints": [ { "method": "GET", "path": "/x402/google-news", "price_usd_per_call": 0.0239 }, { "method": "GET", "path": "/x402/google-search", "price_usd_per_call": 0.02285 }, { "method": "GET", "path": "/x402/web-search", "price_usd_per_call": 0.022545 } ], "endpoints_listed": 22 } ] }
