## 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-predictions-models-catalog-2f9e7341
```

Example prompt: Show me all the prediction models Onvexia has available — I want to know which blockchains and assets are covered before I start querying for signals.

## When to prefer this

Use this endpoint as a discovery step before calling specific Onvexia prediction endpoints — it tells you what models exist, what assets they cover, and what chain data is available. Prefer this over guessing model IDs or asset coverage when building integrations against Onvexia's multi-chain analytics suite.

## Known failure modes

- Empty data array if no models match the properties filter
- 402 Payment Required if USDC payment header is missing or payment fails
- Invalid or malformed properties parameter returns 400 error
- Rate limiting or authentication issues may return 429 or 401
- Service unavailability returns 503 with no model data

## 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 available prediction model entries and a 'meta' object with documentation URL and endpoint path. Each model entry describes supported assets, chains, and model identifiers usable in subsequent prediction queries.
