## 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-score-history-f9b56661
```

Example prompt: Pull the full score history for BTC from Onvexia — I want to see how its composite blockchain analytics rating has trended over time.

## When to prefer this

Choose this endpoint when you need the temporal evolution of a crypto asset's composite analytics score — not just its current state — enabling trend analysis, backtesting, compliance auditing, or risk monitoring over time. Prefer it over current-score endpoints when historical context matters. Particularly valuable when the depth of coverage (labelled addresses, half a million analysed documents, data back to 2008) is needed for research-grade analysis.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Symbol for an asset not tracked across Onvexia's ten chains may return no results
- Malformed symbol parameter may result in a 400 error
- Payment not completed via x402 protocol results in a 402 Payment Required response
- Rate limiting or quota exhaustion may return a 429 error
- Very new assets without historical data will return minimal or empty time-series

## 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 time-series entries of historical composite analytics scores for the requested asset symbol, plus a `meta` object with documentation links and the endpoint path.
