What Is a Decentralized Search Engine? How Desearch Builds a Web Index on Bittensor
A primer on how Subnet 22 builds Desearch's web index with miners and validators.
Read articleOne search API for AI agents: web, social, people and company search, plus page extraction.
In brief
Desearch is one search API for AI agents: Web and AI Search, Social Search for public data from X, TikTok, Instagram and Facebook, People Search and Company Search, with Extract for clean content from any URL. Search results come with source links you can open and check.
Bittensor is the decentralized network Desearch runs on. Subnet 22 builds Desearch's web index, and Desearch runs the search API on top of it.
AI Search $0.40 per 1,000 items · Web Search $1.00 per 1,000 searches · Extract $0.50 per 1,000 pages · X Search $0.15 per 1,000 posts
Pay as you go. New accounts get $5 in API credits after attaching a card in Console.
People Search and Company Search are billed per person or company delivered, see Pricing.
Search the live web and get answers that link to sources you can open.
Search public posts and profiles on X, TikTok and Instagram, and Facebook Ad Library.
Find people on X, YouTube, LinkedIn and TikTok who match a description.
Find companies from a description, or enrich domains you already have.
Turn any page into clean text, markdown or HTML your agent can use.
Use it through the API, playground, SDKs and MCP.

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 one search API for AI agents: Web and AI Search, Social Search for public data from X, TikTok, Instagram and Facebook, People Search and Company Search, with Extract for clean content from any URL. Desearch runs on Bittensor: Subnet 22 builds Desearch's web index, and Desearch runs the search API on top of it. One API key covers all of it, so an agent can search the web, pull public social data, find people and companies, read pages, or get an answer grounded in the returned sources.
Use Search to find links, snippets, highlights, and an optional summary across the web and X. Use Web Search for SERP-style results without an AI summary. Use Extract when you already have a URL and need clean page content. Use Social Search for X posts, profiles, replies, retweeters, and trends, and for public TikTok, Instagram and Facebook data. Use People Search to find people from a description, and Company Search to find companies from a description or enrich the domains you already have.
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, social retrieval, and people and company search share one API key and developer workflow.
Yes. For AI Search, supported tools: web, twitter. Other values are unsupported and may be rejected (for example, youtube returns 422). To focus web results on specific sites, keep web and add include_domains, for example example.com. TikTok, Instagram and Facebook are not AI Search tools: search them through their own Social Search endpoints. You can also request links only or links with a final summary.
date_filter is optional. When you leave it out, no time window is applied. Search 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 1,000 items, Web Search $1.00 per 1,000 searches, Extract $0.50 per 1,000 pages, and X Search $0.15 per 1,000 posts (X profile lookups $0.15 per 1,000 users). New accounts get $5 in API credits after attaching a card in Console, then pay as they go. People Search and Company Search are billed per person or company delivered, with rates on the pricing page. Each successful billable response reports its cost in USD, and Desearch Console shows your balance, request history, and current rates.
Desearch covers public data on X, TikTok, Instagram and Facebook. X: posts, profiles, replies, retweeters and trends. TikTok: public post search, profiles, comments, hashtags and trending posts. Instagram: public profile search, media, comments and hashtag media. Facebook: public Meta Ad Library search, plus public profile and page posts, post lookup and comments. Private, login, posting and messaging surfaces are not exposed.
People Search finds X profiles, YouTube creators, LinkedIn members and TikTok creators that match a plain-language description, and shows why each one matched. Company Search finds companies from a description, and Company Enrich starts from domains you already have. Both return public contact info and leaders, run as background tasks, and can be exported.
New accounts get $5 in API credits after attaching a card in Console, then pay as they go.
Your agent can set Desearch up itself. Copy one line, paste it into Claude Code, Codex, Cursor or VS Code, and it installs the MCP server and verifies the key.
