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.
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.
Bing Web Search API
For a decade the default independent web search API. Retired on 11 August 2025, taking Web, Image, News, Video, Entity and Custom Search with it.
Retired 11 August 2025
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.

Frequently asked questions
What is the best alternative to Grounding with Google Search?

$14 per 1,000 search queries on Gemini 3.x after 5,000 free prompts per month. Gemini 2.5 models use the older scheme at $35 per 1,000. One prompt can trigger several billed queries.
