CatchAll scans 50,000+ pages per job at ~10,000 pages/minute, applies LLM-based validation via Leiden algorithm clustering, and returns structured JSON records with source citations. In an independent March 2026 benchmark across 6,025 observable events, CatchAll achieved 79.8% recall and F1 score of 0.705 — compared to 0.317 for the next closest competitor. NewsCatcher is ISO-certified, SOC2 Type II–certified, and GDPR-ready, with 99.95% platform uptime and a 5-minute source-to-signal latency. Notable enterprise clients include the US Department of State, Samsung, UC Berkeley, HCOB, and Transparency International (per company website; independently unverifiable).
Exa
Exa (formerly Metaphor, rebranded 2024) is an AI-native search API that uses neural retrieval rather than SERP scraping. Its search index is optimised for semantic relevance rather than keyword ranking, with an Instant mode delivering results in under 180ms and a highlights feature that reduces LLM token usage by up to 90%. In independent FRAMES benchmark testing Exa achieved 54.4% accuracy versus competitors at 44.5% and 21.6%. Exa is SOC 2 Type II certified with a Zero Data Retention option. Notable clients include Cursor, AWS, Databricks, Groq, HubSpot, Cognition (Devin AI), and Monday.com (per company website; independently unverifiable).

CatchAll vs Exa: pros and cons
| CatchAll | |
|---|---|
| + | Highest recall in independent benchmarks: 79.8% vs competitors' 26–32% across 6,025 observable events (March 2026) |
| + | Pay-per-validated-result pricing eliminates token waste — you only pay for records that pass LLM quality checks |
| + | Scans 50,000+ pages per job covering regional press, trade publications, and non-English sources most SERP APIs miss |
| + | Real-time event index with <5-minute source-to-signal latency and 2M+ events indexed daily |
| + | Enterprise-grade compliance: ISO-certified, SOC2 Type II, GDPR-ready, with 99.95% uptime SLA |
| + | Automated Monitors allow scheduled re-runs with built-in deduplication — no custom polling infrastructure needed |
| - | Base mode jobs take ~15 minutes to complete — not suited for sub-second real-time query patterns |
| - | Lite mode is capped at 100 results and lacks the full coverage depth of Base mode |
| - | Smaller ecosystem and community compared to established providers like SerpAPI or Bing Search API |
| Exa | |
|---|---|
| + | 20,000 free searches/month — most generous free tier of any neural search API in this category |
| + | Highlights feature reduces downstream LLM token usage by up to 90%, materially cutting inference costs |
| + | <180ms latency with Exa Instant mode — suitable for user-facing real-time agent applications |
| + | 54.4% accuracy on FRAMES benchmark vs 44.5% and 21.6% for next competitors in independent testing |
| + | SOC 2 Type II certified with Zero Data Retention option for compliance-sensitive pipelines |
| + | Native MCP server and OpenAI-compatible SDK — integrates into existing agent frameworks without glue code |
| - | $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 |
