# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://mesh.heurist.xyz/x402/agents/EtherscanAgent/get_erc20_token_transfers" \
  -H 'content-type: application/json' \
  -d '{"address": {"description": "Token contract address", "required": true, "type": "string"}, "chain": {"description": "Blockchain network where the token is deployed", "enum": ["ethereum", "base", "arbitrum", "zksync", "avalanche", "bsc"], "required": true, "type": "string"}, "debug": {"default": false, "description": "Debug mode flag. ALWAYS use false.", "type": "boolean"}}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
