Barter Deliver

x402 APIPassing, checked 3 min ago

x402 Barter — deposit your half of an accepted trade into escrow. Send deal_id, side ('give' or 'want') and the payload itself; the payload is hashed so either party can prove later what was delivered. Returns the deal status, whether both sides have now delivered, and the release state of the escrow. Nothing but the flat call fee is charged — the goods, not USDC, are what trade here.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://x402-agent-pay.com/x402/barter/deliver' \
  -H 'content-type: application/json' \
  --data-raw '{}'

# 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://x402-agent-pay.com/x402/barter/deliver' \
  -H 'content-type: application/json' \
  --data-raw '{}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
