SlidingBox One-Shot Encrypted Blob Hydrate

Use this endpoint when you need to consume a pre-stored, one-shot encrypted secret that was shared via a SlidingBox pointer. Ideal for burn-after-reading secrets, single-use credential delivery, or any scenario where the sender intentionally wants the payload to be irrecoverably destroyed after one access. Not suitable for repeated reads, durable secret storage, or scenarios where the caller may need to retry — the pointer is gone after one successful call.

• Pointer already consumed (404): the blob was already retrieved; it is permanently gone and cannot be recovered
• Invalid or malformed pointer: the pointer string does not correspond to any stored blob, returns 404
• Payment failure: the x402 micropayment of $0.02 USDC was not successfully processed, retrieval not attempted
• Network or server error: transient 5xx error; caller should NOT retry blindly as a partially processed request may have consumed the pointer
• Pointer never existed: pointer was fabricated or mis-copied, returns 404
