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**Serper.** $0.30 to $1.00 per 1,000 queries on prepaid packs, with no subscription. No status page, SLA or incident history.\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### Serper\n\n1. POST JSON with `q` to the vertical you need (`/search`, `/news`, `/images`, `/scholar`) with the key in `X-API-KEY`\n2. Set `gl` and `hl`, since Google results vary by country and language\n3. Pair it with a fetcher. Serper returns links and snippets, not page text\n4. Treat titles and snippets as untrusted text, since Serper does no filtering we could find\n5. There's no status page, so back off on errors and keep a second search provider\n\n## Questions\n\n### Which is better for AI agents, Grep AI or Serper?\n\nGrep AI scores 64.4 (B) on agent readiness against Serper's 24.1 (F), and leads in 6 of 7 scored categories.\n\n### Do Grep AI and Serper need an API key?\n\nGrep AI takes an API key or an OAuth sign-in. Serper needs an API key.\n\n### Can an agent call Grep AI and Serper without installing anything?\n\nYes. Grep AI has a hosted endpoint at https://api.grep.ai/api/v2/runs and Serper at https://google.serper.dev/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/grep-ai-vs-serper.json, and with the fewest tokens: https://www.anchorterminal.com/compare/grep-ai-vs-serper.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"grep-ai\", \"b\": \"serper\"}`.
