## Kagi Search

Kagi takes the familiar search box and rebuilds the incentives around it. Rather than showing ads or sponsored placements, it is funded entirely by subscriptions, which means results are ranked on relevance instead of who paid. Technically it aggregates several leading search engines, then re-ranks the combined pool and filters out spam and low-quality pages, so you get broad coverage without the clutter.

The control layer is what makes Kagi distinct. You can boost, lower, pin, or block any domain so results reflect your own judgment about trustworthy sources. Search Lenses focus a query on a category like forums, news, or academic material, bangs and snaps jump into or restrict to a specific site, and the interface itself is highly customizable, from which result sections appear to full CSS restyling.

Kagi has also grown into an ecosystem. Quick Answer and the Kagi Assistant generate responses grounded in search results, Kagi Translate handles translation, and Summarize condenses long pages. Beyond the browser, the company ships Orion Browser and related tools such as Kagi News, Maps, and Mail. Query privacy is a core promise: searches are not logged or retained after results are returned.

**Pricing & Plans:** Kagi is paid rather than ad-supported. You can run a limited number of free searches anonymously and get additional searches during a trial, after which subscription plans for individuals, families, teams, and libraries apply. Plans start at a low monthly rate, with API access and some tools billed separately. Check the pricing page for current figures.

- **Ad-free, user-funded results:** Subscriptions replace advertising, so there are no sponsored results, affiliate links, or data sales influencing what you see.
- **Boost, lower, block:** Rank any website up or down, pin favorites, or block domains entirely so your results match your own standards.
- **Quick Answer and Assistant:** Append a question mark to get an AI answer above the results, or chat with the Assistant for deeper tasks with sources included.
- **Search Lenses and bangs:** Restrict searches to categories like forums or news, or jump straight into a specific site's own search with shortcuts.
- **Privacy-first ecosystem:** Translate, Summarize, News, Maps, and the Orion Browser extend the same no-tracking, no-selling approach beyond search.

**Strengths:** Zero advertising and no tracking-based monetization of your searches; Unusually fine-grained control over ranking, sources, and interface; AI answers and summaries grounded in the search results with visible sources; A widening suite of privacy-first tools beyond the search box

**Limitations:** Requires a paid subscription for full use, unlike free ad-supported engines; Search coverage depends on the upstream engines it aggregates rather than its own index; Some ecosystem tools are newer or still rolling out compared with the core search

## Serpex

Serpex provides two core endpoints behind a single API key: a Search endpoint that returns live web results as structured JSON, and an Extract endpoint that converts any URL into clean, readable markdown for AI ingestion. A standard search consumes one credit, and pulling page content along with results lets teams go from discovery to ingestion without juggling a second scraping vendor.

The service is positioned around affordability and throughput. Its published tiers scale from roughly $0.80 per 1,000 requests on small top-ups down to around $0.50 per 1,000 on the $500 tier, with custom pricing for very high volume. Serpex advertises automatic fallback across multiple underlying search sources, so if one source returns nothing the request fails over to another, along with retries and per-source health monitoring.

For developers, there are SDKs and integrations for Python, JavaScript, MCP and LangChain, plus a REST API. New accounts receive free trial credits without a card, and credits are described as non-expiring with a short money-back window on purchases.

**Pricing & Plans:** Pay-as-you-go credit model with a free trial (200 free credits, no card). Published tiers: Starter ~$0.80 per 1,000 requests ($5 top-up), Standard ~$0.65 per 1,000 ($50 top-up) and Scale ~$0.50 per 1,000 ($500 top-up); enterprise volume from ~$0.20 per 1,000. Credits are non-expiring and only successful requests are billed.

- **Search API returning structured JSON:** Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.
- **Built-in content extraction:** Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.
- **Automatic source fallback:** Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.
- **Developer SDKs and integrations:** Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
- **Pay-as-you-go credits:** Only successful requests consume credits, credits do not expire, and volume discounts scale from small top-ups up to high-throughput plans.

**Strengths:** Search and extraction in one API key, reducing vendor sprawl; Competitive pay-as-you-go pricing with volume discounts; Credits never expire and failed requests are not billed; Automatic fallback and retries reduce pipeline fragility

**Limitations:** No ability to pin a specific search engine source; engine selection is handled automatically; Free tier is a credit-based trial rather than an unlimited free plan
