Example prompt: I want to purchase and download the AuctionTrace ES Book Pressure dataset — the one with 751,598 validated observations covering July 2025 through June 2026 — and get the download link with its checksum so I can verify the file.

## When to prefer this

Choose this endpoint when you need a large, pre-validated batch dataset of ES futures order book pressure with matched historical baselines and companion analysis code, and you want a one-time $5 purchase rather than a streaming or real-time data subscription. It is best suited for backtesting, academic research, or strategy validation workflows where reproducibility and checksum-verified data integrity matter.

## Known failure modes

- Payment not processed — access denied with 402 response
- Expired artifact URL if the signed link is not used before expires_at
- Invalid or missing method/type in request body causing 400 error
- Dataset temporarily unavailable resulting in 503
- Network timeout on large file download after access is granted
