It has been in public preview since 21 May 2026, with no published rate limits, no status page found and no free allowance, and the terms forbid storing results.\n\n**SearchAPI.io.** 99.9% SLA on every plan and no incidents on the status page since August. MCP exposes over 100 tools with no toolsets.\n\n## Before you call either\n\n### Kagi Search API\n\n1. Send `POST https://kagi.com/api/v1/search` with a JSON body and `Authorization: Bearer \u003ckey\u003e`, as the OpenAPI file defines. Only `query` is required\n2. Set `limit` to cap results returned. In the mixed `search` workflow the MCP tool applies the cap to each result category separately\n3. Use `extract.count` (1 to 10) only when page text is needed. Extraction is billed at the Extract rate on top of the search\n4. Do not store results. The API terms allow only the transient caching an application needs, and require deletion on termination\n5. On 429 back off before retrying. The response covers both rate limiting and an exhausted usage limit, and no `Retry-After` header is documented\n\n### SearchAPI.io\n\n1. Send the key as `Authorization: Bearer`, not `api_key=` in the URL\n2. Connect the MCP through OAuth or the `X-MCP-Token` header, not the registry's `?token=` URL\n3. Call the REST API with `engine=` when context is tight. The MCP loads over 100 tool definitions\n4. Page Google results with `page`. `num` is fixed at 10\n5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches\n\n## Questions\n\n### Which is better for AI agents, Kagi Search API or SearchAPI.io?\n\nSearchAPI.io scores 51.2 (D) on agent readiness against Kagi Search API's 48.7 (D), and leads in 2 of 7 scored categories. Kagi Search API leads on schema \u0026 documentation, agent ergonomics, security \u0026 auth, maintenance \u0026 community and transparency \u0026 trust.\n\n### Which is cheaper for web search, Kagi Search API or SearchAPI.io?\n\nSearchAPI.io, at $4 per 1,000 requests against $12 per 1,000 requests for Kagi Search API. These are the vendors' published prices for the job.\n\n### Do Kagi Search API and SearchAPI.io need an API key?\n\nKagi Search API needs an API key. SearchAPI.io takes an API key or an OAuth sign-in.\n\n### Can an agent call Kagi Search API and SearchAPI.io without installing anything?\n\nYes. Kagi Search API has a hosted endpoint at https://kagi.com/api/v1/search and SearchAPI.io at https://www.searchapi.io/api/v1/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/kagi-search-vs-searchapi-io.json, and with the fewest tokens: https://www.anchorterminal.com/compare/kagi-search-vs-searchapi-io.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"kagi-search\", \"b\": \"searchapi-io\"}`.
