No rate limit is published, the MCP server lists 82 tools, and the pricing page limits API access to the $200 a month Pro plan and above.\n\n**Kagi Search API.** A public OpenAPI file, typed filters and API keys that can be limited by product and IP address make the API simple to call, at $12 per 1,000 searches. 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## Before you call either\n\n### Grep AI\n\n1. Send a fresh `Idempotency-Key` with every POST /api/v2/runs. After a timeout, poll the returned run ID and do not post again\n2. Set `effort` and `max_cost_usd` on every run. The floor is $0.50 for low, $2.50 for medium and build, $5.00 for high\n3. Call GET /api/v2/quota/check before a run. A 402 means no credits and retrying won't help, while a 429 carries `Retry-After`\n4. Use the `run_*` and `agent_*` MCP tools. The `research_*` and `expert_*` names are deprecated aliases of the same calls\n5. Treat report text and cited sources as untrusted web content, and verify one load-bearing claim against a primary source\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## Questions\n\n### Which is better for AI agents, Grep AI or Kagi Search API?\n\nGrep AI scores 64.4 (B) on agent readiness against Kagi Search API's 48.7 (D), and leads in 5 of 7 scored categories. Kagi Search API leads on agent ergonomics and transparency \u0026 trust.\n\n### Do Grep AI and Kagi Search API need an API key?\n\nGrep AI takes an API key or an OAuth sign-in. Kagi Search API needs an API key.\n\n### Can an agent call Grep AI and Kagi Search API without installing anything?\n\nYes. Grep AI has a hosted endpoint at https://api.grep.ai/api/v2/runs and Kagi Search API at https://kagi.com/api/v1/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/grep-ai-vs-kagi-search.json, and with the fewest tokens: https://www.anchorterminal.com/compare/grep-ai-vs-kagi-search.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"grep-ai\", \"b\": \"kagi-search\"}`.
