Try one (paid call)

x402 servers require a signed payment header. The easiest way to call them is 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 use the official Python SDK:

from x402 import x402Client
from x402.mechanisms.evm.exact import ExactEvmScheme

client = x402Client()
client.register("eip155:*", ExactEvmScheme(signer=my_signer))

# Hit the endpoint — client auto-handles the 402 challenge
resp = client.post(
    "https://power-pack-x402.fly.dev/api/score-email",
    json={"subject": "Quick question about your API rollout",
          "body": "Hey , ..."},
)

Discovery

Each endpoint emits a full Bazaar discovery extension in its 402 response, including:

This means agents browsing the x402 Bazaar (or any vector-indexed registry like x402scan) auto-discover these endpoints by capability — no manual onboarding required.

To see a 402 challenge yourself:

curl -i -X POST https://tradingagents-x402.fly.dev/api/analyze-ticker \
  -H 'content-type: application/json' \
  -d '{"ticker":"NVDA"}'

The payment-required header is base64-encoded JSON. Decode it:

curl -sI -X POST https://tradingagents-x402.fly.dev/api/analyze-ticker \
  -H 'content-type: application/json' \
  | awk '/^payment-required:/ {print $2}' | tr -d '\r' | base64 -d | jq

Reliability

A daily GitHub Actions cron (x402 daily Bazaar self-ping) hits all seven /health endpoints + verifies every 402 challenge still reports eip155:8453, the expected price, and the correct payTo. Failure emails the operator.

Every successful paid call also emits one [LEDGER] JSON line to Fly logs (timestamp, app, endpoint, price, network, payTo, ok, latency) for per-call revenue and latency audit.

Architecture

All seven services share the same proven stack:
