## How to call it through Zero

```sh
zero fetch --capability onvexia-asset-prediction-history-b809cde7
```

Example prompt: Pull the full prediction history for BTC from Onvexia so I can see how their blockchain analytics score has evolved over time.

## When to prefer this

Choose this endpoint when you need a longitudinal view of Onvexia's proprietary blockchain analytics scores for a specific asset — particularly when backtesting signals, monitoring score drift, or conducting due diligence using fused on-chain, document, and labelled-address data across multiple chains. Prefer it over point-in-time prediction endpoints when trend analysis or historical context is required.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Symbol not covered across the ten supported chains returns no results
- Payment of $0.01 USDC not confirmed via x402 results in 402 Payment Required
- Malformed symbol in URL path returns 400 or empty response
- Rate limiting or quota exceeded may return 429
- Historical data may be sparse for newly listed or obscure assets

## 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 containing an array of historical prediction data points for the requested asset symbol, each entry likely including a timestamp, prediction score or rating, and supporting metadata. The meta field includes a link to the full OpenAPI documentation.
