## How to call it through Zero

```sh
zero fetch --capability onvexia-ohlcv-endpoint-304871f3
```

Example prompt: Pull the daily OHLCV candles for Bitcoin from Onvexia for the past 90 days so I can analyze the price trend.

## When to prefer this

Choose this endpoint when you need structured OHLCV candlestick price data for crypto assets, especially lesser-covered tokens across ten chains including data reaching back to 2008. It is well-suited for agents doing on-chain analytics, backtesting, or portfolio analysis where Onvexia's broad multi-chain coverage and document-fused analytics add value over generic market data APIs.

## Known failure modes

- Empty data array if asset or chain is not covered by Onvexia
- Payment failure or 402 response if x402 USDC micropayment is not completed
- Invalid or missing query parameters resulting in an error or empty response
- Rate limiting if too many calls are made in a short window
- Unsupported chain or asset identifier returning no results

## 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

Returns a JSON object with a `data` array containing OHLCV candlestick records (open, high, low, close, volume, and timestamp fields per interval) for the requested asset and time range, plus a `meta` object pointing to the full OpenAPI documentation.
