## 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 bykaranteli-options-flow-tape-2e4e91c5
```

Example prompt: Pull the full Deribit options flow tape for BTC — I want to see the historical daily premium-flow and the complete big-print list, not just the last 24 hours.

## When to prefer this

Choose this endpoint when you need historical depth in Deribit options flow beyond the free 24-hour window — specifically for daily premium-flow trends and large block (big-print) trade lists for BTC or ETH. Prefer this over the free /api/public/options-flow endpoint when multi-day historical context or complete big-print coverage is required for research, backtesting, or institutional flow analysis.

## Known failure modes

- Missing or invalid currency parameter defaults to BTC
- Payment not fulfilled results in 402 error
- Unsupported currency value returns error
- Rate limiting or quota exceeded returns 429
- Service unavailability or Deribit data pipeline issues may return 503

## How this service works

BTC or ETH options tape depth from our own recorded Deribit + OKX flow: the daily premium-flow history plus the full big-print list with strike, expiry, direction, premium, implied volatility and venue.

## Output

A structured dataset containing the daily premium-flow history recorded from Deribit options trading activity, plus a full list of big-print (large block) options trades — extending well beyond the free 24-hour summary window. Data is specific to the requested currency (BTC or ETH).
