# Onvexia Asset Predictions

> Onvexia Asset Predictions is a paid API for AI agents from onvexia.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-19).

Returns a fused blockchain analytics prediction for a single crypto asset, combining on-chain data, labelled addresses, supply-age history, and half a million analysed documents across ten chains.

## 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-predictions-4eb3e62b
```

Example prompt: Pull the Onvexia prediction for ETH — I want the fused on-chain reading including labelled address signals and supply-age history.

## When to prefer this

Choose this endpoint when you need a single, fused on-chain prediction for a specific crypto asset that synthesises document analysis, labelled address data, and supply-age history across ten chains — particularly when you want a pre-packaged analytical signal rather than raw on-chain data you must interpret yourself. Prefer this over generic blockchain explorers when you need an opinionated analytical score rather than raw transaction data.

## Known failure modes

- Unknown or unsupported asset symbol returns an empty data array
- Payment failure (402) if USDC payment is not correctly attached via x402 protocol
- Symbol format mismatch (e.g. lowercase vs uppercase) may return no results
- Asset not covered across the ten supported chains returns empty results
- Rate limiting or network errors return standard HTTP error codes

## 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 a fused prediction reading for the requested asset symbol, including on-chain analytics signals, labelled address data, supply-age history derived from data going back to 2008, and metadata pointing to the full OpenAPI documentation. The data array holds the prediction results and the meta object includes endpoint and docs references.
