// Performs a web search and returns relevant results with snippets
Performs a web search and returns relevant results with snippets. Agents can request it by capability ID web.search, or by plain intent — EntRoute resolves phrases like “web search”, “search the web” and “google search” to this capability.
EntRoute currently lists 50+ endpoints from 22 providers for web.search, priced from $0.001 to $0.5 per call, settled in USDC on Base. The quickest responds in about 12ms at the 95th percentile. Every endpoint below is re-probed every 10 minutes for a valid 402 payment challenge; the ordering blends measured success rate, latency and price rather than provider claims.
These phrases resolve to this capability with intent-based discovery.

Frequently asked questions about Web search
How much does a web search API call cost?
Endpoints listed for web.search on EntRoute are priced from $0.001 to $0.5 per call. Payment is per request — there is no subscription, account or API key. Prices shown are read from each endpoint's live 402 response, not from a provider-supplied catalogue.
How do AI agents pay for web search endpoints?
Via the x402 protocol. The agent calls the endpoint, receives an HTTP 402 Payment Required response describing the price and recipient, signs a stablecoin payment (USDC on Base), and retries the request with proof of payment. The whole exchange takes seconds and needs no human approval.
How many providers offer web search?
50+ endpoints are currently listed for web.search across 22 providers. That number moves as endpoints are added and as failing ones are demoted.
Are these web search endpoints verified?
Each one is probed every 10 minutes to confirm it still returns a well-formed 402 challenge on a payable network. Endpoints whose 7-day success rate drops below 50% are moved out of the ranked list into fallbacks with an explicit exclusion reason, so an agent can decide whether to retry them.
