## 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-asset-scores-8de50008
```

Example prompt: Pull the Onvexia analytics score for ETH — I want the full fused reading including supply-age history and labelled address signals.

## When to prefer this

Choose this endpoint when you need a single, pre-computed, multi-dimensional analytics score for a specific crypto asset that fuses on-chain data, document-level research, labelled address analysis, and supply-age history — especially when you need breadth across ten chains without building your own analytics pipeline. Prefer it over raw blockchain node queries or single-signal analytics when you want a fused 'one reading per asset' output ready for downstream decision-making.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Payment not included or insufficient (402 Payment Required)
- Symbol path parameter malformed or missing
- Rate limiting if too many calls in short period
- Endpoint may return partial data if coverage for the asset is limited

## 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

Returns a JSON object with a 'data' array containing the composite analytics score(s) for the requested asset symbol, and a 'meta' object pointing to the full OpenAPI documentation. The score fuses on-chain signals, labelled address data, supply-age history back to 2008, and analysis across half a million documents covering thousands of assets on ten chains.
