## 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-galaxy-top-scores-ac59c7fd
```

Example prompt: Pull the top-ranked crypto assets from Onvexia's Galaxy score leaderboard — I want to see which tokens are leading based on their fused on-chain analytics, labelled address data, and document coverage.

## When to prefer this

Choose this endpoint when you need a ranked leaderboard of top blockchain assets by a holistic, fused analytics score rather than a single metric. It is especially useful when you want multi-chain coverage (ten chains), historical depth back to 2008, and a score that blends on-chain signals with document-level research — as opposed to endpoints that offer raw price data, simple market cap rankings, or single-chain analytics.

## Known failure modes

- Empty data array returned if no assets match filter criteria
- 402 Payment Required if x402 micropayment of $0.003 USDC is not included
- Invalid properties filter parameter returns schema validation error
- Rate limiting or quota exhaustion if called too frequently
- Service unavailable if Onvexia's analytics pipeline is refreshing data

## 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 top-ranked blockchain assets scored by Onvexia's Galaxy composite metric, which fuses on-chain analytics, labelled address data, half a million analysed documents, and supply-age history going back to 2008 — returned with metadata pointing to the full OpenAPI schema.
