Search defaults to advanced mode at $5 per 1,000 when `mode` is left out.\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### Parallel Search and Task APIs\n\n1. Pass `mode: \"fast\"` on every search. Without it you pay the advanced rate\n2. Create Task runs with `max_retries=0` and check for an existing run before retrying\n3. Give an `objective` plus two or three short `search_queries`. That's what ranks the excerpts\n4. On 402, check available balance rather than total. Running tasks reserve credit\n5. Prefer natural-language source guidance to domain filters. The docs say filters can cut result quality\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 Parallel Search and Task APIs or You.com APIs\n\n- [Brave Search API + MCP vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/brave-search-mcp-vs-parallel-search-api.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 Parallel Search and Task APIs](https://www.anchorterminal.com/compare/exa-mcp-vs-parallel-search-api.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 Parallel Search and Task APIs](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-parallel-search-api.md)\n- [Firecrawl MCP vs You.com APIs](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-you-com-api.md)\n- [Linkup vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/linkup-vs-parallel-search-api.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 SearchAPI.io](https://www.anchorterminal.com/compare/parallel-search-api-vs-searchapi-io.md)\n- [Parallel Search and Task APIs vs SerpApi](https://www.anchorterminal.com/compare/parallel-search-api-vs-serpapi.md)\n- [Parallel Search and Task APIs vs Serper](https://www.anchorterminal.com/compare/parallel-search-api-vs-serper.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 Valyu](https://www.anchorterminal.com/compare/parallel-search-api-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 You.com APIs](https://www.anchorterminal.com/compare/serpapi-vs-you-com-api.md)\n- [Serper vs You.com APIs](https://www.anchorterminal.com/compare/serper-vs-you-com-api.md)\n- [Tavily API + MCP vs You.com APIs](https://www.anchorterminal.com/compare/tavily-mcp-vs-you-com-api.md)\n- [Valyu vs You.com APIs](https://www.anchorterminal.com/compare/valyu-vs-you-com-api.md)\n- [Fetch (MCP reference server) vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/fetch-reference-server-vs-parallel-search-api.md)\n- [Fetch (MCP reference server) vs You.com APIs](https://www.anchorterminal.com/compare/fetch-reference-server-vs-you-com-api.md)\n",
