The API supports 40+ languages and markets, configurable freshness filters, and SafeSearch. 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.

Bing Web Search API vs Webz.io: pros and cons

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
Webz.io
+ Dark web and paste site coverage via Cyber API — unique in this category for threat intelligence and OSINT workflows
+ 500M+ indexed web sources at publication time — covers regional and niche sources not in mainstream search engine indexes
+ 240+ language filtering enables global monitoring across non-English sources that SERP APIs do not cover
+ Entity-level pre-filtering reduces downstream NLP processing needed to extract structured signals from raw text
+ Government and intelligence agency clients — proven in high-security and regulated environments (per company website; independently unverifiable)
- Pricing not publicly disclosed — requires enterprise sales contact before technical evaluation
- Not a SERP API — does not return search engine result pages; unsuitable for SEO rank tracking or Google result retrieval
- Dark web data may trigger additional procurement and legal review before production use in some organisations
- Smaller developer community and fewer third-party integrations than SERP API providers like SerpAPI or Exa
