Exa vs Zenserp: pros and cons
| Exa | |
|---|---|
| + | 20,000 free searches/month — most generous free tier of any neural search API in this category |

| - | $7/1K searches is expensive for bulk SERP volume use cases — DataForSEO is ~11,600× cheaper per query |
| - | Deep Search ($12/1K) and Deep Reasoning ($15/1K) costs accumulate quickly for multi-step research workflows |
| - | Optimised for semantic relevance, not exact keyword SERP matching — not a drop-in replacement for rank-tracking tools |
