Vercel has made DeepSeek Search and DeepSeek Fetch available through AI Gateway. DeepSeek Search finds relevant pages with titles, URLs and summaries; DeepSeek Fetch retrieves page content as Markdown for a model to read.
One key, any tool-calling model
Both tools work with any model that supports tool calling, using one AI Gateway API key. No separate DeepSeek account is required, and the same tools can be kept when switching model providers.
Versions and setup
The helpers are available in AI SDK 6.0.321 and later on v6, or 7.0.160 and later on v7. Vercel’s instructions use pnpm add ai@latest and say to set AI_GATEWAY_API_KEY; both helpers can be passed in the tools configuration to combine search with page retrieval. Alternative search tools can be used with DeepSeek Fetch if DeepSeek Search fails. Vercel says search fallback is model-directed, so provider order and retry limits are best effort.
Pricing
DeepSeek Search and DeepSeek Fetch each cost $0.75 per 1,000 billable requests. Failed requests, timeouts and empty results have no tool charge, and model tokens are billed separately. AI Gateway provides one API for calling models, tracking usage and cost, and configuring routing, retries and failover.
