Frequently Asked Questions

Reference for the Valyu Answer endpoint that blends search results into AI-generated answers via POST /v1/answer.

Valyu Answer costs $0.02 per call on xpay. No subscription, no minimums. Pay only for the calls you make. New accounts get $5 in free credits.

Connect the Valyu API MCP endpoint to your client — Claude Code: claude mcp add --transport http valyu "https://valyu.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"; Cursor/Windsurf/Cline/VS Code: same URL in mcp.json. The agent will see valyu_answer as a callable tool with the input schema and run it directly. (Unified across all providers: https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY, then xpay_run with toolPath valyu/valyu_answer.)

Yes — that's exactly what xpay is for. You don't need a Valyu API account or API key. Sign up at xpay.tools (Google or email), get $5 free credit, and run Valyu Answer immediately. Billing flows through your xpay balance.

Valyu Answer accepts 12 input parameters: end_date, country_code, streaming, fast_mode, data_max_price, query…. See the input schema and runnable form on this page for details and to test live.
