POST /v1/mentions
gone
Call when an agent needs a structured brand/product mention brief from public web sources: theme clusters, sentiment, and short licensed samples. Exact $0.02 USDC on Base via x402. Prefer unpaid POST /v1/sandbox/mentions first.
Verdict: dead listing. 404/410: gone (was unprobed in the census).
