# Onvexia Asset Fundamentals

> Onvexia Asset Fundamentals is a paid API for AI agents from onvexia.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-19).

## 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-fundamentals-dd3a5f03
```

Example prompt: Pull the full on-chain fundamentals for ETH from Onvexia — I want supply history, labelled addresses, and any document-derived insights going back as far as the data allows.

## When to prefer this

Choose this endpoint when you need comprehensive, fused fundamental data for a crypto asset in a single call — especially when you need multi-chain coverage, labelled address data, supply/age history, or document-derived research insights. Prefer it over generic on-chain data APIs when depth and historical reach (back to 2008) matter, or when you need cross-chain fundamentals in one response rather than aggregating multiple sources.

## Known failure modes

- Unknown or unsupported asset symbol returns empty data array
- Symbol format mismatch (e.g. wrong casing or alias) may yield no results
- Payment failure or insufficient USDC balance returns 402 status
- Rate limiting may occur on repeated rapid calls
- Data may be sparse or empty for very new or obscure tokens not yet covered

## 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 with a `data` array containing fused fundamental metrics for the requested asset — expected to include on-chain analytics, labelled address information, supply and age history, and insights derived from analysed documents across up to ten chains. A `meta` field points to the full OpenAPI schema for detailed field definitions.
