## 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-social-signal-crypto-asset-social-sentiment-50d78b2e
```

Example prompt: What's the current social signal score for ETH on Onvexia — is there strong community buzz or is sentiment weak right now?

## When to prefer this

Choose this endpoint when you need on-chain-aware social sentiment fused with blockchain analytics context, rather than purely off-chain social media scrapers. Onvexia is particularly useful when you want social signals correlated with labeled addresses and supply history — giving sentiment a chain-verified grounding. Prefer this over generic sentiment APIs when the asset is a lesser-known token across multiple chains that mainstream sentiment tools may not cover.

## Known failure modes

- Unknown or unsupported ticker symbol returns empty data array
- Rate limiting or payment failure returns 402 Payment Required
- Malformed symbol path parameter returns 400 Bad Request
- Asset exists on-chain but has insufficient social data coverage, returning sparse or empty results
- Network timeout if upstream social data aggregation is slow

## 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 social signal metrics and sentiment data for the requested asset symbol, including aggregated scores derived from half a million+ analyzed documents and social sources tracked by Onvexia across ten chains.
