How this service works
Thousands of assets across ten chains, half a million analysed documents, labelled addresses and supply-age history reaching back to 2008 — fused into one reading per asset. REST, SQL, GraphQL and MCP.
Output
A JSON array of named entities extracted by NLP from Onvexia's corpus of blockchain research documents for the requested asset, including entity labels, types, and associated metadata. The response includes a data array and a meta object pointing to the full OpenAPI spec.
Example use cases
Mapping key actors in DeFi protocol coverage
“For the Uniswap token UNI, pull all the named entities Onvexia has extracted from its analysed documents — I want to see which organizations, developers, and projects are most frequently associated with it in blockchain research.”
Due diligence on a new crypto asset
“I'm researching Avalanche before investing — can you fetch the NLP entities Onvexia has identified for AVAX so I can see what people, projects, and events are linked to it across half a million analysed documents?”
Competitive intelligence on rival blockchain projects
“Get me the named entities from Onvexia's research corpus for Solana — I want to know which organizations and key figures appear most in coverage of SOL compared to what we see for other layer-1 chains.”
Technical details
Endpoint
GEThttps://onvexia.com/v1/nlp/entities/%7Basset%7DWhen to prefer
Choose this endpoint when you need NLP-derived named entity extraction specifically from a large corpus of blockchain research and analytics documents (500k+), spanning ten chains and dating back to 2008, for a specific crypto asset — rather than general web NLP or on-chain data providers that lack document-level entity analysis.
Side effects
- Unknown or unsupported asset identifier returns empty data array
- Malformed asset parameter may return a 400 or empty result
- Payment not completed (402) blocks access to results
- Rate limiting or quota exceeded returns error response
- Endpoint may return sparse results for low-coverage or newly listed assets
