Buying and delivery
Send a valid unsigned request first and inspect the HTTP 402 PAYMENT-REQUIRED challenge. Only sign payment terms within your own approved budget. PennyBot executes automatically, returns structured JSON, and uses durable order/result handling for supported replay and recovery. Keep the original request and payment authorization if delivery is uncertain.
The detailed Markdown contract is authoritative for product-specific inputs, limits, chargeability, non-claims, replay behavior and failure handling. This landing page is a concise discovery surface, not a replacement for the contract.
