Example prompt: I need to buy the Receipt Ledger Deduper offline tool from Speedbot to check for duplicate Base USDC transfer claims before I finalize my bookkeeping export — please use my email orders@myco.io, generate the required checkout key and request ID, and confirm digital delivery consent.

## When to prefer this

Choose this endpoint when you need an offline, dependency-free Node.js tool specifically for deduplicating Base USDC receipt entries and resolving conflicting transfer claims before producing a bookkeeping export, and you want a one-time purchasable download rather than a hosted API call.

## Known failure modes

- Invalid or missing email format causes rejection
- checkout_key not exactly 64 hex characters causes validation failure
- request_id shorter than 16 characters or absent causes rejection
- digital_delivery_consent not set to true blocks purchase
- Payment of 1.5 USDC not included or declined causes failed transaction
- Retry with a different request_id may create a duplicate order — must reuse same request_id on retry
