How this service works
Topic ranking — Ranked social topics for a window. Returns topics + window_hours.
Output
An array of ranked topic entries (or empty array if no rows in the specified window), plus a meta object containing coverage and provenance details including a link to the full OpenAPI spec. Empty data array means no topics found in range, not that the feature is unsupported.
Example use cases
Daily crypto narrative briefing
“Give me a ranked list of the most discussed blockchain topics in the last 24 hours — I want to see what narratives are dominating crypto discourse today.”
Weekly trend comparison for research
“What were the top trending on-chain topics over the past 72 hours? I'm writing a weekly market summary and need to know which themes got the most traction.”
Real-time topic monitoring for trading signals
“Check what blockchain topics are trending right now with a 6-hour window — I want to catch any emerging narratives early before they hit mainstream coverage.”

Endpoint
GEThttps://onvexia.com/v1/topics/rankWhen to prefer
Choose this endpoint when you need a ranked, aggregated view of trending blockchain/crypto topics derived from a large corpus of analyzed documents (500k+) spanning ten chains. Prefer it over raw on-chain data feeds when you want narrative intelligence — what people and analysts are discussing — rather than raw price or transaction data. Especially useful for detecting emerging themes before they reach mainstream coverage.
Side effects
- Empty data array returned when no documents fall within the specified window_hours range
- Invalid window_hours value may result in a 400 or default behavior falling back to 24h
- Payment not processed (x402 flow failure) results in 402 response before data is returned
- Stale or incomplete coverage for niche chains may reduce ranking accuracy
