The alternatives
unlob
$0.40/1kOur own index, admitted rather than ranked. Metadata-only passage hits, six coverage-graph traversal tools, an MCP server, and an endpoint that tells you why any URL is or is not in the index. Smaller than the well-funded incumbents, and considerably cheaper than all of them.
Grounding with Google Search
$14/1kGoogle's first-party grounding for Gemini. The best index in the world, billed per search query on top of tokens, and only usable from Gemini.
Perplexity Sonar
$14/1kSearch and synthesis in one call. You get an answer rather than results, which is convenient until you need to control retrieval yourself.
Grounding with Bing Search
Microsoft's designated successor to the retired Bing Search API, available only inside Azure AI Foundry. A platform commitment, not an API swap.
OpenAI web search tool
The built-in search tool in the Responses API. Zero integration work if you are already on OpenAI, and no control over retrieval whatsoever.
DataForSEO
$0.60/1kIndustrial SERP infrastructure built for SEO tooling rather than agents. The cheapest per query in the field, with the lowest-level API to match.
Parallel Search
$1/1kA suite of web search, extraction and research APIs on a proprietary index, from the former Twitter CEO. The closest competitor to unlob by thesis.
Serper
$1/1kThe cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.
Brave Search API
$5/1kA genuinely independent index of 40B+ pages, sold as a conventional search API with an LLM-context option. Long the default independent choice.
Free developer tier removed February 2026

Frequently asked questions
What is the best alternative to Bing Web Search API?
It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 queries. If you need the largest possible index, Bing Web Search API may still be the right tool — we say so on our comparison page rather than pretending otherwise.
Is Bing Web Search API still available?
No. Retired 11 August 2025. Anything built on it needed migrating, which is why this category saw so much movement in 2025 and 2026.
Does Bing Web Search API own its own web index?
Yes — Bing index. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.
How much does Bing Web Search API cost?
No longer sold. API creation was disabled in March 2025 and the service retired that August.
