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-chains-list-0a7b7f22
```

Example prompt: What blockchain networks does Onvexia cover? I want to know which chains I can pull analytics and asset data from before I start querying.

## When to prefer this

Use this endpoint as the first step when integrating with Onvexia to discover available blockchain networks before querying asset-level analytics. Prefer this over hardcoding chain identifiers, as it reflects the current supported set across Onvexia's ten-chain coverage universe.

## Known failure modes

- Empty data array if no chains are indexed yet
- 402 Payment Required if USDC micropayment is not attached
- Invalid properties filter parameter returns empty or error response
- Network timeout on the REST endpoint
- Malformed JSON response if service is degraded

## 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 listing supported blockchain networks and a 'meta' object containing documentation links and endpoint info. The data array contains chain identifiers and associated metadata for each supported network.
