Each service also exposes a /sample endpoint that returns a sample request body and expected response shape — no payment required. Use these to understand the API contract before making a paid call:
curl -s https://power-pack-x402.fly.dev/api/score-email/sample | jq
curl -s https://suprapack-x402.fly.dev/api/find-skill/sample | jq
x402 servers require a signed payment header. Easiest with a wallet-equipped client like x402-proxy:
npx x402-proxy https://suprapack-x402.fly.dev/api/find-skill \
--body '{"query":"stripe webhook","limit":3}'
Or the official Python SDK:
from x402 import x402Client
from x402.mechanisms.evm.exact import ExactEvmScheme
client = x402Client()
client.register("eip155:*", ExactEvmScheme(signer=my_signer))
resp = client.post(
"https://power-pack-x402.fly.dev/api/score-email",
json={"subject": "Quick question about your API rollout", "body": "Hey , ..."},
)
