Before you call either

Web Search Tool on Amazon Bedrock AgentCore

  1. Call tools/list on the gateway and take the tool's name from it. AWS's call examples name gateway tools by target and tool
  2. Keep query to 200 characters and maxResults between 1 and 25 (default 10). The published schema states these limits only in descriptions
  3. Check the target's connector version before sending filters. Version 1.1.0, the default, exposes only query and maxResults
  4. Keep each result's URL and title with any answer built from it. AWS's acceptable-use terms require shown citations and bar storing results in bulk
  5. On a throttled request, wait the retryAfter seconds in the error body. The default quota is 10 Web Search requests a second, adjustable

SearchAPI.io

  1. Send the key as Authorization: Bearer, not api_key= in the URL
  2. Connect the MCP through OAuth or the X-MCP-Token header, not the registry's ?token= URL
  3. Call the REST API with engine= when context is tight. The MCP loads over 100 tool definitions
  4. Page Google results with page. num is fixed at 10
  5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches
