Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/trend-detectWhen to prefer
Use this endpoint when you need a real-time, multi-source trend signal specifically from developer and knowledge communities (Wikipedia, GitHub, Hacker News). Prefer it over social media trend APIs when the target audience is technical users or researchers, and when you want velocity/momentum rather than raw popularity.
Side effects
- Missing or empty ?topic= parameter — likely returns error or empty result
- Topic not found on any of the three sources — may return zero velocity or null scores
- Rate limiting or payment failure — 402 payment required if x402 header not provided
- Network timeout if upstream Wikipedia/GitHub/HN APIs are slow
