This endpoint speaks x402: an unpaid request returns HTTP 402 with machine-readable payment terms, your agent pays the $0.01 USDC in USDC on-chain, and retries automatically. Pays to 0x7d9d1821d15B9e0b8Ab98A058361233E255E405D.

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://mesh.heurist.xyz/x402/agents/EtherscanAgent/get_transaction_details" \
  -H 'content-type: application/json' \
  -d '{"chain": {"description": "Blockchain network to query.", "enum": ["ethereum", "base", "arbitrum", "zksync", "avalanche", "bsc"], "required": true, "type": "string"}, "debug": {"default": false, "description": "Debug mode flag. ALWAYS use false.", "type": "boolean"}, "txid": {"description": "Transaction hash starting with 0x", "required": true, "type": "string"}}'

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