• get_price_quote

  CDK Bot: lock the current price for a digital product and get USDC payment instructions. Returns a quote_id valid for 5 minutes. After paying, use confirm_purchase with the tx_hash and quote_id.

  Parameters:

  • game_id (required) — string — Game ID to get a price quote for
  • chain — string — Payment chain. Use "base-sepolia" for sandbox testing with mock keys.

• confirm_purchase

  CDK Bot: receive the product key after paying. Two ways to pay: (1) one-shot — pass x_payment, a signed EIP-3009 "exact" X-PAYMENT header (from accepts[] in get_price_quote); the facilitator settles it gaslessly, no tx_hash needed. (2) two-step — send USDC yourself, then pass tx_hash + quote_id.

  Parameters:

  • game_id (required) — string — Game ID being purchased
  • chain — string — Payment chain (default: "base")
  • tx_hash — string — Two-step flow: the USDC payment transaction hash on Base. Provide this OR x_payment.
  • quote_id — string — Required WITH tx_hash — locks the quoted price and prevents front-running. Not needed with x_payment.
  • x_payment — string — One-shot flow: a base64-encoded EIP-3009 "exact" X-PAYMENT payload signed by the buyer wallet for accepts[0] from get_price_quote. Settles gaslessly via the facilitator — no tx_hash/quote_id needed.
