How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
Returns a JSON object with: a boolean 'viral' flag indicating whether the topic has crossed a virality threshold, 'hn_hits' (integer count of relevant Hacker News mentions), 'reddit_hits' (integer count of relevant Reddit mentions), and 'momentum_score' (float combining recency and volume of attention across both platforms).
Example use cases
Startup launch timing intelligence
“Before we publish our launch post, can you score the current attention momentum for 'open source LLM' to see if the topic is viral and how many HN and Reddit hits it's getting?”
Investor trend signal monitoring
“I'm researching whether 'nuclear fusion' is picking up mainstream tech community momentum — can you pull the momentum score, viral status, and hit counts from Hacker News and Reddit?”
Content strategy virality check
“We're about to post an article on 'supply chain automation' — can you check if that topic has any viral momentum right now, including the HN hits, Reddit hits, and overall momentum score?”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/osint/attention-momentumWhen to prefer
Choose this endpoint when you need a fast, quantified signal of real-time attention momentum for a specific topic across Hacker News and Reddit — the two highest-signal communities for tech and startup trends. Prefer it over generic social listening tools when you need a single numeric momentum score suitable for programmatic decision-making (e.g. timing a launch, routing research effort, or triggering alerts). It is particularly useful for OSINT pipelines, content scheduling agents, and investor signal workflows where $0.02/call economics make high-frequency polling viable.
Side effects
- Topic or keyword not provided — request returns an error or empty result
- Upstream Hacker News or Reddit APIs unavailable — may return zero counts or an error
- Very niche or obscure topics may return zero hits and a momentum_score of 0 with viral=false
- Rate limiting or payment failure via x402 protocol blocks the call
- Ambiguous multi-word keywords may yield low-quality signal due to loose matching
