Space Ticket

by Flow in Onchain & crypto

x402 APIPassing, checked 2 h ago

Gigabyte Space — ask-the-cast ticket. Pay $0.50 USDC on Base and put one written question into the live Space speaker queue: when the cast calls your ticket, you come up as a speaker and your question is answered on air, by name. One ticket buys one question. House rules: no shilling without a graded record, claims carry numbers — never product, always results. Listening is free; the ticket buys the question, not a verdict.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.5.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://flow-kg4x.vercel.app/api/space/ticket' \
  -H 'content-type: application/json' \
  --data-raw '{"handle":"yourhandle","name":"Your Name","question":"What does the verdict score actually measure?"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://flow-kg4x.vercel.app/api/space/ticket' \
  -H 'content-type: application/json' \
  --data-raw '{"handle":"yourhandle","name":"Your Name","question":"What does the verdict score actually measure?"}' \
