CatchAll vs Perplexity Sonar API: overview

CatchAll

CatchAll is the web search API from NewsCatcher (Y Combinator–backed), built around complete dataset retrieval rather than top-ranked results. 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).

Perplexity Sonar API

Perplexity Sonar is a family of online language models that combine real-time web retrieval with LLM reasoning, accessible via an OpenAI-compatible REST API. Unlike traditional search APIs that return URL lists or raw SERP data, Sonar collapses retrieval and synthesis into one call and returns a cited, grounded answer. The model family includes sonar (fast/cheap), sonar-pro (higher accuracy), sonar-reasoning (chain-of-thought with citations), and sonar-deep-research (autonomous multi-step investigation). Pricing is token-based: sonar costs $1/M input tokens and $5/M output tokens plus a $5/1K request fee for online search. Perplexity AI was founded in 2022 and has raised over $500M in venture funding. The API is widely used in developer projects, LangChain integrations, and enterprise AI applications.

CatchAll vs Perplexity Sonar API: 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
Perplexity Sonar API
+ Collapses retrieval + reasoning into one OpenAI-compatible call — drop-in replacement for GPT-4o with live web access
+ sonar-deep-research performs autonomous multi-step web research across many sources, not just top-ranked results
+ Cited responses with source URLs enable downstream citation auditing without additional extraction
+ Four model tiers from fast/cheap (sonar) to chain-of-thought (sonar-reasoning) to deep research — match cost to task complexity
+ Over $500M raised — well-capitalised for a sustained roadmap vs. smaller bootstrapped SERP API providers
- Token-based pricing creates unpredictable costs for high-throughput pipelines — no fixed-rate-per-query option
- Returns synthesised answers, not raw SERP results — unsuitable for SEO rank tracking, SERP structure research, or raw URL enumeration
- No published recall or coverage benchmarks — web coverage completeness cannot be independently verified
- sonar-deep-research latency (multi-step, minutes) is unsuitable for user-facing real-time features
