POST /api/run/linkup/deep-search
unprobed
Linkup — DEEP agentic search: iterative multi-query retrieval for hard or multi-hop questions where one-pass search misses. Same params as linkup/search (`q` + outputType/dates/domain filters). Slower (tens of seconds) and 5× the price — escalate here only after linkup/search or exa/search come back thin. For full multi-step research reports, parallel/task (10-30¢) is the bigger rung.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
