How this service works
Buy a gift card from ~550 US brands (Amazon, Target, DoorDash, Uber ...) and more countries; the card is issued to the agent's owner (registered STB agent key with gift cards turned on required). This call prices one card for a $0.02 USDC fee on Base and returns the exact USDC total, a pay_url and a claim token. Find product ids and amounts with GET /x402/giftcards/catalog/?country=USA.
Output
Returns the exact USDC total required (including the $0.02 service fee on Base), a pay_url to complete payment, and a claim token that will be used to retrieve the issued gift card after payment is confirmed.
Example use cases
Agent-purchased DoorDash gift card
“Quote me a $25 DoorDash gift card for the USA — give me the USDC amount and the payment link so I can buy it right now.”
Corporate gifting with referral credit
“I want to send a $100 Target gift card to someone in the USA; use my referral handle @mystore and give me the quoted USDC price and claim token.”
International gift card pricing
“How much would a £20 gift card from a UK brand cost in USDC? Use product ID GBP-AMAZON-20 for country UK and give me the pay URL.”
Technical details
Endpoint
POSThttps://x402.spendthebits.com/x402/giftcards/quote/?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically price and initiate a gift card purchase for ~550 US or international brands using USDC on Base, especially when operating as an AI agent with a registered SpendTheBits agent key. Prefer this over generic gift card APIs when payment is crypto-native (USDC/Base) and you need a claim token workflow.
Side effects
- Invalid or unrecognized product_id returns an error suggesting to check the catalog endpoint
- Amount not matching fixed denominations for the selected card results in a validation error
- Unregistered or gift-card-disabled STB agent key returns an authorization error
- Unsupported country name returns a catalog error
- Network issues or Base chain congestion may delay response
