Exa - Pros & Cons
Pros
- ✓Neural search returns genuinely different results than keyword APIs — worth the switch for research agents
- ✓Content-return collapses search + fetch + parse into one call, cutting agent latency
- ✓'Similar to URL' is unique among search APIs and drives real product wins for sales/discovery tools
- ✓First-party MCP server means zero glue code for Claude Desktop and Cursor users
Cons
- ✗Pricing gets confusing fast when you mix search + content + Websets on one bill
- ✗Websets can burn hours before returning results; not a fit for interactive UX
- ✗Neural search index is smaller than Google's — misses very-long-tail queries
- ✗Structured extraction is powerful but requires prompt tuning to be reliable
Serper - Pros & Cons
Pros
- ✓Cheapest mainstream Google Search API — roughly one-third the cost of SerpAPI at scale
- ✓Very fast (typical 1–2s) and returns clean JSON, no HTML parsing needed
- ✓Free tier of 2,500 credits is enough to prototype an entire agent before committing
- ✓Wide endpoint coverage: Search, News, Scholar, Places, Maps, Images, Shopping, Autocomplete
- ✓First-class or community-maintained integrations in every major agent framework and MCP client
Cons
- ✗Google-only — no Bing, Yahoo, or DuckDuckGo endpoints (SerpAPI wins here)
- ✗No built-in LLM-friendly summarization; you get raw results and do the ranking yourself
- ✗Credits expire on paid plans if unused — over-provisioning wastes money
- ✗Small team compared to SerpAPI, so support and SLA coverage is thinner
- ✗Regional result variability requires passing `gl` and `hl` params correctly for non-US markets
