# Onvexia Universe Search

> Onvexia Universe Search 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).

Search and discover blockchain assets across ten chains using a text query, returning matched assets from Onvexia's fused analytics universe

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-universe-search-735852d1
```

Example prompt: Search Onvexia's blockchain universe for assets matching 'Uniswap' and return up to 10 results — I want to see which tokens across their ten chains match that name.

## When to prefer this

Use this endpoint when you need to discover or identify which blockchain assets exist within Onvexia's coverage universe before querying deeper analytics endpoints, or when you want to search assets by name/symbol across multiple chains simultaneously. Prefer this over chain-specific explorers when cross-chain coverage and fused analytics provenance matter.

## Known failure modes

- Empty data array returned when query matches no assets in the universe
- Limit parameter exceeding 200 may be rejected or clamped
- Malformed query string may return empty results without an explicit error
- Payment not processed (x402 protocol failure) blocks the call
- Rate limiting if too many calls are made in rapid succession

## 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 of matched asset records from Onvexia's universe (thousands of assets across ten chains), and a `meta` object containing coverage and provenance information including a link to the full OpenAPI spec. An empty data array means no assets matched the query, not that the metric is unsupported.
