Scraping services emulate browsing and can be brittle (layout changes, blocks, inconsistent outputs). Yandex Search API is a managed cloud API with predictable latency on high workload, and controls that make it easier to build agent workflows (source constraints, locale, safety filtering, etc.).

Yes — you can build “controlled web search” where your agent operates only on allowed sources (e.g., documentation, knowledge bases, partners). You can limit search by 20 domain parameters simultaneously using url: host: rhost: or domain: parameters in the query.

• Web search: results returned in XML or HTML (including Base64 rawData)
• Web search + Extract: currently supports plain text format
• Image search: XML or JSON
• Smart search: JSON

Smart Snippets return original, query-relevant excerpts from webpages found by Yandex Search API. They provide more context than standard search snippets while using significantly fewer tokens than the full page.

The excerpts are taken directly from the source pages and are not generated, summarized, or rewritten by AI. This allows developers to preserve the original wording of a source and use it in RAG pipelines, AI agents, research applications, citation-based answers, and other source-grounded scenarios.

Instead of downloading and processing every full webpage, an application receives the parts most relevant to the user’s query. This reduces unnecessary context, token consumption, processing time, and model costs.

Smart Snippets can return excerpts from up to 20 documents per request, with a maximum of 2,048 tokens per document. Content availability may vary depending on whether a webpage is accessible and how its content is structured.

Search API has quotas (organizational limits that support can raise on request) and hard limits (architectural constraints e.g. 400 characters maximum search query length). Per-feature limits are listed in the docs; enterprise customers can request quota increases.

Yes. Commercial usage is governed by the Yandex Search API Terms of Use plus the Yandex Cloud platform terms. For privacy/data processing, refer to Yandex Cloud’s privacy/compliance materials (including SCCs where applicable).

The search database is built by Yandex’s crawler: it discovers and refreshes pages using internal/external links, Sitemaps, signals like Yandex Metrica, and it respects robots.txt directives. It also considers things like page availability/status codes and size limits for indexing.

Create a Yandex Cloud account, grant the required roles, generate credentials, and run your first request. Our docs walk through the setup end-to-end.
