## How to call it through Zero

```sh
zero fetch --capability onvexia-blockchain-analytics-signals-3c121f5d
```

Example prompt: Pull the latest Onvexia analytics signals for Bitcoin — I want the fused on-chain reading including supply-age history and any labelled address context.

## When to prefer this

Choose this endpoint when you need a fused, multi-source analytical signal for a crypto asset that combines on-chain data (labelled addresses, supply-age history back to 2008) with document-level research across half a million analysed documents — especially when you want a single authoritative reading rather than raw on-chain data you must interpret yourself. Prefer it over generic on-chain data providers when document-backed context and cross-chain breadth (ten chains) matter.

## Known failure modes

- Empty data array returned if the asset or chain is not covered by Onvexia's ten supported chains
- Payment of 0.002 USDC not received or x402 handshake fails, resulting in 402 Payment Required
- Invalid or unrecognised properties filter parameter yields empty or error response
- Rate limiting if too many calls are made in quick succession
- Stale data if the asset has not been recently indexed

## 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 per-asset analytics signals — including labelled address metadata, supply-age history derived from data reaching back to 2008, and scores fused from on-chain data and half a million analysed documents — plus a `meta` object pointing to full OpenAPI documentation.
