Pricing detail. The Turbo search processor is $1 per 1,000; Basic and Advanced are both $5 per 1,000. The Task API, which is what most agent workloads actually use, runs $5 to $2,400 per 1,000 depending on processor.
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.
Exa
$7/1kNeural, embeddings-first search over a proprietary index, sold alongside content extraction, answers and agentic research products.
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
Mojeek
A UK independent crawler and index, running since 2004. Small by comparison, but genuinely its own — and the oldest independent index still standing.
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.
Serper
$1/1kThe cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.
Google Custom Search JSON API
$5/1kGoogle's own programmable search endpoint. Real Google results, a hard 10,000/day ceiling, and terms written for site search rather than agents.
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.

Frequently asked questions
What is the best alternative to Parallel Search?
It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 queries against Parallel Search's $1. If you need the largest possible index, Parallel Search may still be the right tool — we say so on our comparison page rather than pretending otherwise.
Does Parallel Search own its own web index?
Yes — Proprietary web index and retrieval infrastructure. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.
How much does Parallel Search cost?
The Turbo search processor is $1 per 1,000; Basic and Advanced are both $5 per 1,000. The Task API, which is what most agent workloads actually use, runs $5 to $2,400 per 1,000 depending on processor.
