I was just looking into these as DeepSeek Harness w/ Qwen3.8-27B relies heavily on search. I was going to go with Serper.dev[0] $1 per 1000 (or lower in quantity).

The providers[1] behind this Web Search API have very different rates:

    Ceramic.ai: $0.25 per 1,000 requests
    Linkup:     $5.00 per 1,000 requests
    Exa:        $7.00 per 1,000 requests
