## When to prefer this

Choose this endpoint when you need structured OHLCV candlestick price history for a crypto asset, especially when you want data enriched with Onvexia's deep on-chain analytics context (labelled addresses, supply-age history, document analysis across ten chains). Prefer this over generic market data APIs when you need historical depth back to 2008, or when your use case benefits from the same platform also offering labelled address data and on-chain analytics in a unified data environment.

## Known failure modes

- Unknown or unsupported symbol returns empty data array
- Malformed symbol parameter may return 400 error
- Rate limiting or payment failure (x402 protocol) may return 402 Payment Required
- Symbol disambiguation failure if ticker exists on multiple chains without chain qualifier
- Response may return empty data array for very new or obscure tokens with insufficient coverage

## 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 fields per time period) for the requested symbol, plus a `meta` object with documentation link and endpoint path. Data coverage may extend back to 2008 for major assets across up to ten supported blockchains.
