Linkup

Agentic web search that returns ranked sources, a cited answer, or JSON in a shape you define — plus clean markdown for any single page.

About

Linkup answers its own 402 on Base and publishes an OpenAPI covering exactly the two routes sold here, which is where these field names, types and enums come from. No Linkup account or key is involved: the treasury settles the provider's own x402 in USDC and the buyer pays the list price plus the Apiosk fee. The deep search mode costs Linkup five times the standard one and is not offered here; fast and standard are.
