Two API hosts. Answer and Research return 'Missing Authentication Token' on ydc-index.io.\n\n## Before you call either\n\n### Tavily API + MCP\n\n1. Try `X-Tavily-Access-Mode: keyless` first for search and extract, then switch to a key or x402 when the limit hits\n2. Send the key in `Authorization: Bearer`, not `?tavilyApiKey=` in the MCP URL\n3. On 429, wait for `Retry-After`. A 432 or 433 means a spend limit, and retrying won't help\n4. Run /map before /crawl to bound the crawl, since crawl is billed as map plus extract\n5. Research is async and runs 4 to 250 credits. Create the task, then poll /research/{request_id}\n\n### You.com APIs\n\n1. For unattended runs call GET https://api.you.com/v1/search, handle the 402 and pay with x402. It's half the MPP price for search\n2. Use `https://api.you.com/mcp?profile=free` to try search with no key (100 queries a day)\n3. Send Answer, Research and Finance Research to api.you.com. On ydc-index.io they fail with 'Missing Authentication Token'\n4. Pass `?tools=` with only the tools you need to keep the MCP tool list short\n5. On 429, wait for `Retry-After` and watch `X-RateLimit-Remaining` before the next burst\n\n## Other comparisons with Tavily API + MCP or You.com APIs\n\n- [Brave Search API + MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/brave-search-mcp-vs-tavily-mcp.md)\n- [Brave Search API + MCP vs You.com APIs](https://www.anchorterminal.com/compare/brave-search-mcp-vs-you-com-api.md)\n- [Exa API + MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/exa-mcp-vs-tavily-mcp.md)\n- [Exa API + MCP vs You.com APIs](https://www.anchorterminal.com/compare/exa-mcp-vs-you-com-api.md)\n- [Firecrawl MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-tavily-mcp.md)\n- [Firecrawl MCP vs You.com APIs](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-you-com-api.md)\n- [Linkup vs Tavily API + MCP](https://www.anchorterminal.com/compare/linkup-vs-tavily-mcp.md)\n- [Linkup vs You.com APIs](https://www.anchorterminal.com/compare/linkup-vs-you-com-api.md)\n- [Parallel Search and Task APIs vs Tavily API + MCP](https://www.anchorterminal.com/compare/parallel-search-api-vs-tavily-mcp.md)\n- [Parallel Search and Task APIs vs You.com APIs](https://www.anchorterminal.com/compare/parallel-search-api-vs-you-com-api.md)\n- [SearchAPI.io vs Tavily API + MCP](https://www.anchorterminal.com/compare/searchapi-io-vs-tavily-mcp.md)\n- [SearchAPI.io vs You.com APIs](https://www.anchorterminal.com/compare/searchapi-io-vs-you-com-api.md)\n- [SerpApi vs Tavily API + MCP](https://www.anchorterminal.com/compare/serpapi-vs-tavily-mcp.md)\n- [SerpApi vs You.com APIs](https://www.anchorterminal.com/compare/serpapi-vs-you-com-api.md)\n- [Serper vs Tavily API + MCP](https://www.anchorterminal.com/compare/serper-vs-tavily-mcp.md)\n- [Serper vs You.com APIs](https://www.anchorterminal.com/compare/serper-vs-you-com-api.md)\n- [Tavily API + MCP vs Valyu](https://www.anchorterminal.com/compare/tavily-mcp-vs-valyu.md)\n- [Valyu vs You.com APIs](https://www.anchorterminal.com/compare/valyu-vs-you-com-api.md)\n- [Fetch (MCP reference server) vs Tavily API + MCP](https://www.anchorterminal.com/compare/fetch-reference-server-vs-tavily-mcp.md)\n- [Fetch (MCP reference server) vs You.com APIs](https://www.anchorterminal.com/compare/fetch-reference-server-vs-you-com-api.md)\n",
