# NetIntel Crypto OHLC Candles

> NetIntel Crypto OHLC Candles is a paid API for AI agents from netintel.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns historical OHLC candlestick data for major crypto assets — hourly or daily, up to 300 candles — with period stats, and supports a price-at-date lookup mode.

## 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 netintel-crypto-ohlc-candles-7f7c52e9
```

Example prompt: Can you pull the daily OHLC candles for Bitcoin in USD for the last 60 days, including the period high, low, and change percentage?

## When to prefer this

Choose this endpoint when you need no-API-key OHLC candlestick history for major crypto assets with automatic Coinbase/Kraken fallback, especially for price-at-date lookups or period stats (change %, high, low) without building your own exchange integration. Best for agents needing quick historical crypto price data in USD, EUR, or GBP with a simple GET request.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty candles
- Requesting more than 300 daily candles or 12 hourly candles (300 candles max) may be capped
- Invalid date format for date= parameter causes a parsing error
- Unavailable asset on Coinbase with Kraken also lacking data results in no candles returned
- stale=true flag indicates cached data may be older than 5 minutes due to upstream issues

## How this service works

Historical OHLC candles for any major crypto asset — hourly or daily, up to 300 candles, with period stats (change %, high, low) — from Coinbase Exchange with Kraken fallback, no API key. Also a price-at-date mode: pass date=YYYY-MM-DD for that day's candle and close. USD, EUR, or GBP quotes; 5min cache.

## Output

Returns a JSON object containing an array of OHLC candles (time, open, high, low, close, volume), period statistics (open, close, average volume, change %, period high and low), the data source (coinbase or kraken), quote currency, start/end timestamps, candle count, cache age in seconds, and optionally a single-day close price when using date mode.
