On 429, check the credit balance before backing off. The same code means out of credit\n2. Pass `reasoningDepth: \"S\"` to research unless you need more. The MCP default is L at $1.50\n3. Start with `depth=fast` and `outputType=searchResults`. Deep costs $0.05, ten times as much\n4. Send the key as an `Authorization: Bearer` header, not `?apiKey=` or a command-line argument\n5. Poll `linkup-get-research` with the task id. Research runs take minutes\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## Other comparisons with Linkup or Tavily API + MCP\n\n- [Brave Search API + MCP vs Linkup](https://www.anchorterminal.com/compare/brave-search-mcp-vs-linkup.md)\n- [Brave Search API + MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/brave-search-mcp-vs-tavily-mcp.md)\n- [Exa API + MCP vs Linkup](https://www.anchorterminal.com/compare/exa-mcp-vs-linkup.md)\n- [Exa API + MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/exa-mcp-vs-tavily-mcp.md)\n- [Firecrawl MCP vs Linkup](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-linkup.md)\n- [Firecrawl MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-tavily-mcp.md)\n- [Linkup vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/linkup-vs-parallel-search-api.md)\n- [Linkup vs SearchAPI.io](https://www.anchorterminal.com/compare/linkup-vs-searchapi-io.md)\n- [Linkup vs SerpApi](https://www.anchorterminal.com/compare/linkup-vs-serpapi.md)\n- [Linkup vs Serper](https://www.anchorterminal.com/compare/linkup-vs-serper.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 Tavily API + MCP](https://www.anchorterminal.com/compare/parallel-search-api-vs-tavily-mcp.md)\n- [SearchAPI.io vs Tavily API + MCP](https://www.anchorterminal.com/compare/searchapi-io-vs-tavily-mcp.md)\n- [SerpApi vs Tavily API + MCP](https://www.anchorterminal.com/compare/serpapi-vs-tavily-mcp.md)\n- [Serper vs Tavily API + MCP](https://www.anchorterminal.com/compare/serper-vs-tavily-mcp.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 Linkup](https://www.anchorterminal.com/compare/fetch-reference-server-vs-linkup.md)\n- [Fetch (MCP reference server) vs Tavily API + MCP](https://www.anchorterminal.com/compare/fetch-reference-server-vs-tavily-mcp.md)\n",
