## 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-leading-indicators-3332bf03
```

Example prompt: Pull Onvexia's leading indicators for BTC — I want the full fused on-chain reading including supply-age history and labelled address signals.

## When to prefer this

Choose this endpoint when you need a fused, multi-signal on-chain leading indicator reading for a specific crypto asset — especially when you want supply-age history, labelled address data, and document-derived analytics combined into a single response. Prefer it over generic price APIs when predictive or early-warning on-chain signals are needed, and over single-chain analytics when cross-chain coverage (ten chains) is required.

## Known failure modes

- Unknown or unsupported symbol returns an empty data array
- Malformed symbol parameter returns a 400 error
- Payment not included or insufficient USDC results in a 402 Payment Required response
- Rate limiting or quota exceeded returns a 429 error
- Backend analytics pipeline delay may return stale or partial 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 containing an array of leading indicator data points for the requested asset symbol, along with metadata including a link to the full OpenAPI specification. The data array may include fused on-chain metrics such as supply-age distributions, labelled address activity, document-derived signals, and composite scores derived from analysis across ten blockchain networks.
