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 object with a `data` array containing the requested blockchain analytics records (asset metrics, labelled addresses, supply-age data, or document-derived insights) and a `meta` object pointing to the full OpenAPI documentation at onvexia.com/openapi.json
Example use cases
Token supply age research
“Can you use Onvexia to show me the supply-age history for Bitcoin going back as far as their data allows? I want to see how old the coins in circulation are.”
Cross-chain asset comparison
“Query Onvexia's GraphQL for on-chain metrics on Solana and Avalanche assets — I need a side-by-side read on their token activity and any labelled addresses.”
DeFi project address labelling
“Look up labelled blockchain addresses for Uniswap on Onvexia — I want to know which wallets they've categorised and what their document analysis says about the project.”
Technical details
Endpoint
GEThttps://onvexia.com/graphqlWhen to prefer
Choose this endpoint when you need rich, fused blockchain analytics combining on-chain data, document analysis, and labelled addresses across ten chains in a single GraphQL query. Prefer it over REST alternatives when you want flexible field selection across assets. Ideal when historical supply-age data going back to 2008 or large-scale document coverage (500k+ docs) is required for research or enrichment.
Side effects
- Payment not provided or insufficient USDC — returns 402 Payment Required
- Malformed GraphQL query — returns error with query parse details
- Unsupported chain or asset identifier — returns empty data array
- Rate limiting if too many calls in rapid succession
- GraphQL schema mismatch if querying fields not covered by the current schema
