> Onvexia GraphQL Blockchain Analytics is a paid API for AI agents from onvexia.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-19).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability onvexia-graphql-blockchain-analytics-3bdf7b0c
```

Example prompt: Pull the on-chain analytics for ETH from Onvexia — I want labelled address data, supply-age history, and any analyzed documents about it across all the chains they cover.

## When to prefer this

Choose this endpoint when you need rich, fused blockchain analytics — including labelled addresses, historical supply-age data, and analyzed document intelligence — across up to ten chains via a flexible GraphQL interface. Prefer it over REST alternatives when your query structure is complex or relational, and over generic block explorers when you need pre-analyzed, labelled, and cross-chain aggregated data rather than raw transaction records.

## Known failure modes

- Empty data array if the queried asset or address is not in the coverage universe
- Payment failure (402) if USDC payment of $0.001 is not included or insufficient
- Malformed GraphQL query returns a parse or validation error
- Unsupported chain or asset identifier returns no results
- Rate limiting or timeout on complex queries spanning many chains

## 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 history, document analysis results) and a `meta` object with documentation links and the endpoint path. The structure and depth depend on the GraphQL query supplied.
