CatchAll vs Bing Web Search API: overview

CatchAll

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).

As an Azure service it inherits Microsoft's compliance framework including SOC 2, ISO 27001, GDPR, and FedRAMP certifications. Bing serves 900M+ searches per month and its index is one of the world's three largest web indexes alongside Google and Baidu. Pricing starts at $3/1K transactions; a free tier of 250 calls/month is available on the F0 tier. The Bing Search API has been available since approximately 2012.

CatchAll vs Bing Web Search 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
Bing Web Search API
+ FedRAMP certified — the only major web search API formally approved for US federal government production workloads
+ Second-largest independent web index globally after Google — covers content not available via Google-only SERP APIs
+ Full Azure compliance stack: SOC 2, ISO 27001, GDPR, HIPAA-eligible — covers regulated industry procurement requirements
+ 10+ result types (entities, computational answers, spelling corrections, news) from a single endpoint
+ $3/1K queries with no minimum commitment — competitive pricing for an enterprise-grade, compliance-certified index
- Free tier capped at 250 calls/month — insufficient to test a production pipeline before billing begins
- Bing returns ranked results only — no coverage-first enumeration, LLM validation, or event deduplication for AI pipelines
- Microsoft has been consolidating Bing API features into broader Azure AI products — long-term standalone API availability is uncertain
- Bing's market share (~3%) means its index query distribution differs from Google — some verticals have thinner coverage for non-US audiences
