How this service works
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.
Output
A structured brand/product mention brief including theme clusters derived from aggregated public mentions, overall and per-source sentiment scores, and short licensed mention samples sourced from channels such as Reddit, web pages, and review sites.
Example use cases
Competitor sentiment analysis for product launch
“Before we launch, can you pull a mention brief for our competitor 'NovaPods' from Reddit and web sources over the past 60 days — English, up to 80 results — and summarize the main themes people are complaining or excited about?”
Brand health check for a regional market
“I need a brand mention brief for 'Zelta Skincare' targeting Germany in German, pulling from web and reviews over the last 14 days, with at least 40 results — what are people saying and what's the overall sentiment?”
Market research brief for investor deck
“Can you gather a structured mention brief for 'FlowDesk' from Reddit, web, and reviews over the last 90 days — up to 100 results in English — so I can see the top themes and sentiment clusters to put in our investor presentation?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/mentions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a ready-made, structured brand or product mention brief that aggregates theme clusters, sentiment, and licensed samples from multiple public sources in one call. Prefer the unpaid sandbox endpoint POST /v1/sandbox/mentions first for testing. This endpoint is ideal for market research, competitive intelligence, or reputation monitoring workflows where a pre-structured brief — not raw search results — is required. At $0.02 USDC per call it is cost-effective for per-query workflows; use it when you need multi-source aggregation across Reddit, web, reviews, and X with configurable geo, language, and time window filters.
