Example prompt: I want to pull ByKaranteli's crypto derivatives data — liquidations, funding rates, open interest, options gamma, ETF flows, and CFTC positioning across six venues — can you get me a prepaid access key?

## When to prefer this

Choose this endpoint when you need a single prepaid credential to access ByKaranteli's suite of crypto derivatives data including multi-venue liquidation models, funding rates, open interest, options gamma, ETF flows, and CFTC COT positioning — particularly when you want aggregated cross-venue derivatives analytics in one place rather than querying individual exchange APIs separately.

## Known failure modes

- Insufficient payment — USDC payment of exactly $10 not received, key not issued
- Invalid payment — x402 payment protocol not followed correctly, returns error
- Rate limit or duplicate request — key already issued for this payment, balance already credited
- Network error — bykaranteli.com unreachable, no response returned
- Schema mismatch — unexpected properties in request body cause rejection

## How this service works

Six-venue liquidation model with real liquidation prints overlaid, funding rates, open interest, options gamma, ETF flows and CFTC positioning. Free.

## Output
