Best for

AI agents that need fast web search results with page content

Pricing

Pay as you go, with no monthly fee listed. Search costs $0.005 to $0.006 per request by mode. Fetch costs $0.001 to $0.006 per request. Research costs $0.25 to $2.50 per request. The pricing page lists 4,000 free queries, and startups can apply for $5,000 in credits. Enterprise pricing is custom. The page does not state a price per 1,000 calls; the per-request range implies $5 to $6 per 1,000 for Search (estimate).

What it covers

Open web. The pages read did not list individual search engines. Search modes are Fast, Standard and Deep. Fetch returns page content in Standard or Pro modes. Research runs asynchronously and takes 1 to 10 minutes.

Citations and verification

The pages read did not describe claim-level citation checking. Confirm before relying on source attribution.

API
