Before Microsoft retired it on August 11, 2025, Bing Web Search cost $15 per 1,000 calls for web results only (the S2 tier) or $25 per 1,000 with image, news, video and entity answers included (S1), after 1,000 free calls a month. Those prices applied from May 1, 2023.
It cannot be bought today at any price. Searlo's web search returns the same kind of ranked result list for $0.30 per 1,000 at the Scale pack rate.

Is the Bing Search API still available, and what replaced it?
No. Microsoft retired the Bing Search APIs on August 11, 2025 — existing instances were decommissioned and new signups closed, so there is no price at which you can buy it today. Microsoft's own migration path is Grounding with Bing Search inside Azure AI Agents.
That replacement is an agent feature, not a search endpoint: you get web-grounded model answers through Azure AI Agents rather than a ranked result set you can parse. If what you actually needed was the JSON — results, positions, links — you need a search API, and Searlo is a drop-in of that shape at $0.30 per 1,000 queries against live Google results.

What should replace the Bing Search API for AI agents?
It depends on how your agent used Bing. If it ran inside Azure AI Agents and only needed grounded answers, Microsoft's own successor is Grounding with Bing Search: the agent gets web-grounded model answers inside Azure.
If your agent called Bing as a tool and read the results itself, it needs a search API that returns that list: titles, links and snippets it can quote and cite. Searlo's GET /search/web returns it for 1 credit. Its MCP server gives Claude, Cursor and other MCP clients a web search tool with no code to write, and POST /search-and-scrape adds the text of each page for agents that read before they answer.

FAQ
Frequently Asked Questions
Is the Bing Search API still available, and what replaced it?
No. Microsoft retired the Bing Search APIs on August 11, 2025 — existing instances were decommissioned and new signups closed, so there is no price at which you can buy it today. Microsoft's own migration path is Grounding with Bing Search inside Azure AI Agents. That replacement is an agent feature, not a search endpoint: you get web-grounded model answers through Azure AI Agents rather than a ranked result set you can parse. If what you actually needed was the JSON — results, positions, links — you need a search API, and Searlo is a drop-in of that shape at $0.30 per 1,000 queries against live Google results.
Is Bing Search API really deprecated?
It is fully retired, not just deprecated. Microsoft's lifecycle announcement set the retirement date at August 11, 2025: existing instances were decommissioned and the product is no longer available for use or new customer signup. Microsoft directs customers to Grounding with Bing Search as part of Azure AI Agents, which returns web-grounded model answers rather than a parseable result set.
How long does it take to migrate from Bing API to Searlo?
Most developers complete the migration in under an hour. The main changes are: (1) swap the base URL, (2) update your API key header, and (3) map a few response field names. The REST pattern is very similar.
Does Searlo return Google results instead of Bing?
Yes. Searlo returns real-time Google search results, which account for ~90% of global search traffic — a different, generally richer result set than Bing's index.
How does Searlo pricing compare to the old Bing API?
Until it was retired on August 11, 2025, Bing Web Search cost $15 per 1,000 calls for web results only (S2) or $25 per 1,000 with images, news, video and entities (S1), after 1,000 free calls a month; those prices applied from May 1, 2023. Bing billed per call through an Azure subscription. Searlo sells one-time credit packs, $0.30 per 1,000 searches at the Scale pack rate, with no recurring fee, 1-year validity for new users and unlimited credits on legacy accounts.
What should replace the Bing Search API for AI agents?
If your agent ran inside Azure AI Agents and only needs grounded answers, Microsoft's successor is Grounding with Bing Search. If your agent called Bing as a tool and read the results itself, use a search API that returns the result list: Searlo's GET /search/web (1 credit), its MCP server for Claude, Cursor and other MCP clients, or POST /search-and-scrape when the agent should read the pages too.
Does Searlo support MCP protocol?
Yes. Searlo supports the Model Context Protocol (MCP), which Bing API did not. This lets AI tools like Claude, Cursor, and VS Code connect to Searlo for web search without any code.
