## 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-blockchain-analytics-graphql-api-9e32f92e
```

Example prompt: Pull Onvexia's on-chain analytics for Ethereum — I want labelled address data, supply-age history, and any analysed document coverage they have for ETH.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
