Path address: The address, `0x`-prefixed, any case. Query: limit, cursor, issuerContract, action (see docs). Docs: https://docs.tracefast.xyz/api/risk-blacklist-events.md

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.
curl: see the payment challenge
