How Desearch scores on an open search benchmark
In Desearch’s open benchmark, five providers answered the same 250 same-day news questions. An LLM judge read every cited page to score source relevance, answer quality, and groundedness. Desearch led on groundedness and the composite; Exa led on answer quality. The code and data are public.
Composite score by provider
Run 16 Jul 2026 · 250 same-day news questions · score / 100, higher is better
| Provider | Source relevance | Answer quality | Groundedness | Composite |
|---|---|---|---|---|
| Desearch | 85.3 | 86.4 | 65.7 | 79.7 |
| Exa | 85.5 | 90.0 | 56.3 | 78.1 |
| GPT-5-mini | 76.8 | 88.8 | 62.0 | 75.9 |
| Tavily | 73.4 | 86.8 | 59.0 | 73.1 |
| Perplexity sonar-pro | 67.8 | 88.4 | 49.2 | 68.4 |
Composite = 40% source relevance + 30% answer quality + 30% groundedness. An LLM judge (gpt-5.4-mini) reads every cited page. Run by Desearch; raw scoreboard on GitHub.

I just connected mine to Bittensor TAO subnet 22, Desearch, with an API endpoint for X data to help me with subnet analysis.
The results are getting where they should be.

SN22 is becoming an intelligence layer for agents. And behind agents come predictions, then portfolio management.
Revenue and aligned incentives. The market probably hasn't fully priced this yet.

The forecasting environments just got richer.
Starting this Thursday, miners can choose to take on the cost of news retrieval via Desearch.

Desearch integration complete.
crustty now has full social sentiment guidance, and it's integrated (weighted) in his subnet valuations. All thanks to Bittensor SN22, Desearch.

Desearch AI is somewhat like Google but decentralized and smarter.
AI-powered search to deliver smart, summarized results. APIs for developers to integrate decentralized search.

With the Desearch API, Vericore pulls signals from X and Reddit to verify miner outputs, while miners use the same API to add context and deliver better results.
Vericore's predictive evidence gathering with AI scoring becomes more comprehensive.

Read the docsDesearch is a search API for AI agents, built on Bittensor Subnet 22. It returns current, source-linked context from the web and X (Twitter), plus Reddit, Wikipedia, YouTube, Hacker News, and arXiv. One API key covers AI Search, Fast Search, Extract, and X Search, so an agent can search, read pages, pull X data, or get an answer grounded in the returned sources.
Use Search to find links, snippets, highlights, and an optional summary across selected sources. Use Extract when you already have a URL and need clean page content. Use the X API for posts, profiles, replies, retweeters, and trends, or Web Search for SERP-style results without an AI summary.
Traditional search APIs usually return a ranked list of links. Desearch packages structured results for agents, including source URLs, relevant passages, dates when available, and an optional summary alongside the sources. Web search, page extraction, and social retrieval share one API key and developer workflow.
Yes. Choose from the web, X, Reddit, Wikipedia, YouTube, Hacker News, and arXiv for each Search request. You can also apply a date filter and request links only or links with a final summary.
Search supports recency filters and includes publication dates when a source provides them. Extract fetches the current version of a URL instead of returning a cached page snapshot. Exact freshness still depends on the source and endpoint you use.
Search returns structured results with a title, source link, snippet, relevant highlights, and publication date when available. Ask for links only when your agent will do the reasoning, or include a final summary when you want an answer alongside the supporting sources.
Call the REST API directly, use the Python or JavaScript SDK, or connect through MCP. Desearch also provides guides for LangChain, LlamaIndex, CrewAI, ElizaOS, OpenClaw, and function-calling workflows.
Pricing is usage-based. Reference rates as of 7 May 2026: AI Search $0.40 per 1000 items, Fast Search $0.10 per 100 searches, Extract $0.50 per 1000 pages, and X Search $0.15 per 1000 posts (X profile lookups $0.15 per 1000 users). Each successful billable response reports its cost in USD, and Desearch Console shows your balance, request history, and current rates.
