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**SerpApi.** Over 100 engines behind one GET URL, with `json_restrictor` field selection and `output=md`. 25 incidents on the status feed from July to 1 October 2026, including an outage across all APIs on 10 September.\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### SerpApi\n\n1. Use the MCP with `Authorization: Bearer`, not the key-in-path URL the README leads with\n2. Read `serpapi://engines/\u003cengine\u003e` before calling a new engine, since `params` isn't typed\n3. Add `json_restrictor` or `output=md` to cut tokens, and `mode: compact` on the MCP\n4. A 429 means either the hourly limit or an empty balance. Check the account before retrying\n5. Repeat a search within the hour and the cached copy is free. Set `no_cache=true` only when freshness matters\n\n## Questions\n\n### Which is better for AI agents, Grep AI or SerpApi?\n\nGrep AI scores 64.4 (B) on agent readiness against SerpApi's 62.5 (B), and leads in 3 of 7 scored categories. SerpApi leads on agent ergonomics, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Grep AI and SerpApi need an API key?\n\nGrep AI takes an API key or an OAuth sign-in. SerpApi needs an API key.\n\n### Can an agent call Grep AI and SerpApi without installing anything?\n\nYes. Grep AI has a hosted endpoint at https://api.grep.ai/api/v2/runs and SerpApi at https://serpapi.com/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/grep-ai-vs-serpapi.json, and with the fewest tokens: https://www.anchorterminal.com/compare/grep-ai-vs-serpapi.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"grep-ai\", \"b\": \"serpapi\"}`.
