Endpoint
GEThttps://onvexia.com/v1/nlp/trends/%7Basset%7DWhen to prefer
Choose this endpoint when you need NLP-derived narrative and sentiment trend signals specifically sourced from a large corpus of blockchain-related documents (500k+ analysed), rather than social media sentiment scrapers or price-only feeds. Particularly useful when historical narrative context back to 2008 and multi-chain coverage matters.
Side effects

- Asset not covered across the ten supported chains returns no results
- Malformed asset path parameter may return 400 or empty response
- Payment failure (x402) blocks access if USDC micro-payment is not completed
- Rate limiting or quota exhaustion returns 429
