Rates are the cheapest directly comparable web search call — roughly ten results, no extraction and no summarisation — because that is the only way a table across credit systems, token pricing and per-request pricing means anything. Where a vendor does not publish a flat per-1,000 rate they are omitted from this table and covered in full on the landscape page. Figures read from each vendor’s own pricing page on 5 August 2026.

When Grounding with Bing Search is the better choice

A comparison page that cannot name a scenario where the competitor wins is an advertisement. Here are the real ones.

Choose Grounding with Bing Search

  • You are already on Azure AI Foundry, where it requires essentially no integration.
  • Enterprise agreements and compliance posture that already run through Microsoft.
  • Bing’s index quality.

Choose unlob

  • You want a standalone API rather than a platform.
  • Model independence.
  • Predictable, published per-query pricing.
  • Graph traversal and coverage auditing.

Frequently asked questions

Is Grounding with Bing the same as the old Bing Search API?

No. The Bing Search API was a standalone REST endpoint you could call from anywhere. Grounding with Bing Search is a tool inside Azure AI Foundry agents. Migrating means adopting the platform, not changing a base URL — which is precisely why the retirement forced so many rewrites.

Check the claims yourself

The free tier is 10,000 requests a month with no card. That is enough to test coverage, latency and result quality against your own queries — which is a better comparison than this page.
