No published rate limits and no Retry-After or backoff guidance.\n\n**You.com APIs.** x402 and MPP on Web Search and Finance Research, with no account needed. Two API hosts. Answer and Research return 'Missing Authentication Token' on ydc-index.io.\n\n## Before you call either\n\n### Valyu\n\n1. Set `max_price` and `max_num_results` on every search to bound cost\n2. Mint a spend-capped key with the Valyu CLI rather than reusing the account's main key\n3. Call `valyu_search`. The legacy per-vertical MCP tools stop working on 2026-12-01\n4. A 206 means some sources failed. Check which before treating results as complete\n5. DeepResearch is async. Poll `valyu_deepresearch_status` rather than waiting in one call\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 Valyu or You.com APIs\n\n- [Brave Search API + MCP vs Valyu](https://www.anchorterminal.com/compare/brave-search-mcp-vs-valyu.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 Valyu](https://www.anchorterminal.com/compare/exa-mcp-vs-valyu.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 Valyu](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-valyu.md)\n- [Firecrawl MCP vs You.com APIs](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-you-com-api.md)\n- [Linkup vs Valyu](https://www.anchorterminal.com/compare/linkup-vs-valyu.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 Valyu](https://www.anchorterminal.com/compare/parallel-search-api-vs-valyu.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 Valyu](https://www.anchorterminal.com/compare/searchapi-io-vs-valyu.md)\n- [SearchAPI.io vs You.com APIs](https://www.anchorterminal.com/compare/searchapi-io-vs-you-com-api.md)\n- [SerpApi vs Valyu](https://www.anchorterminal.com/compare/serpapi-vs-valyu.md)\n- [SerpApi vs You.com APIs](https://www.anchorterminal.com/compare/serpapi-vs-you-com-api.md)\n- [Serper vs Valyu](https://www.anchorterminal.com/compare/serper-vs-valyu.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- [Tavily API + MCP vs You.com APIs](https://www.anchorterminal.com/compare/tavily-mcp-vs-you-com-api.md)\n- [Fetch (MCP reference server) vs Valyu](https://www.anchorterminal.com/compare/fetch-reference-server-vs-valyu.md)\n- [Fetch (MCP reference server) vs You.com APIs](https://www.anchorterminal.com/compare/fetch-reference-server-vs-you-com-api.md)\n",
